The HM60-08T is equipped with multiple stainless steel impellers in staged construction to generate more powerful pressure output with smooth and quiet operation, suitable for modern homes, garden watering systems and domestic pressure boosting.
The HM60-08T is part of Davey’s popular HM Series of horizontal multistage centrifugal pumps, designed for reliable everyday water supply applications. The pump has internally stainless steel hydraulic parts that ensures excellent resistance to corrosion and wear and increased operational life even in continuous use. The compact horizontal design also simplifies installation in constrained residential environments while providing efficient hydraulic performance.
The HM60-08T has a rugged TEFC motor and an efficient impeller profile that reduces power consumption and provides consistent pressure throughout household plumbing systems. The HM60-08T offers the perfect balance of space saving, energy efficiency and reliable water pressure performance and is often used for water supply applications such as domestic water boosting, irrigation systems and rainwater transfer.
Method of Identification
All product coding within Davey Water Products is based on a standard naming structure used across the product range globally. This coding method is used to simplify product identification, specification referencing, warehouse tracking and technical verification processes. The identification format of the HM Series Horizontal Multistage water pumps is generally organised as follows:
1. Short form of product series.
2. Nominal Durchflussrate.
3. Reference to power or stage.
4. Controller or configuration ID.
For example, the product code HM60-08T begins with “HM”, which signifies the Horizontal Multistage series. “60” refers to the nominal flow of 60 litres per minute (lpm), the flow the pump is designed to deliver during operation. The “08” indicates the pump configuration and stage of performance within the HM60 range. The suffix “T” indicates that the unit is supplied as part of Davey’s Torrium2 controller system for automatic pressure operation.
Davey uses this product identification system internally for inventory organization, technical support, specification tracking and order accuracy. It also enables authorised dealers, technicians and customers to quickly identify the different flow performance, pressure capability and operating configuration of various HM Series models.
Attachment

Pressure Controller
When installed on Davey’s HM centrifugal pump, the Torrium 2 might be an essential integrating component. It is an electrotechnology that is intended to function as a smart controller to control uniform water flow and provide stable pressure in homes and commercial buildings. The only way to do this is to start the pump on a pressure decrease and stop it when the flow rate is low, about 1 litre per minute (LPM).
Reducing the subsequent strain of turning on and off the horizontal multiple-stage electropump is one benefit of purchasing the Torrium2. Water hammer, which could otherwise cause impending damage, is prevented by this soft start-stop, which is only completed by its natural mechanism by very gradually rising and lowering the pace.
Strong Starting Pressure: The sensor that senses an intense water demand and only steps in when the pressure falls to 80% of the maximum output is a key component. This peak serves a versatile function that is determined by the performance of any pump since it is automatically set if the booster pump stops.
Start Adaptability: Water pump cycling is frequently caused by leaks, but the Torrium2 is intelligent enough to distinguish between users who need water and those who are leaking needlessly (such as droplets from the tap). This intelligent controller would adjust to 50% of its last used pressure in situations where an exceptionally low flow rate occurs in order to further prevent further revolution. In the meantime, the Torrium2 would switch back to its adaptive beginning mode in order to activate the Horizontal Multistage pump if the hydration ran above 0.5 LPM.
Dry-Running Protection: Water pumps are always designed to have a full volume of liquid flowing through them. Because of this, whenever the Torrium2 detects a prime loss in Davey’s horizontal multistage centrifugal pump, a fail-safe mechanism is activated to fully stop the pump from operating. The Torrium2 will also retry itself after intervals of 5 and 30 minutes, or even 1, 2, 4, 8, 16, and 32 hours, while the timedown is being reduced. However, it would also restart itself to enable the Horizontal Multistage pump to operate once the proper water pressure entered.

Mechanical Pressure Switch
A mechanical pressure switch, which is installed as an oversight to activate functionality dependent on the desired pressure level, may be attached to Davey’s Horizontal Multistage pump.
Trigger/Closure: Davey’s Horizontal Multistage electropump is turned on or off whenever watering levels climb or fall above the optimal pressure.
Adjustable: End users can adjust the cut-in and out points to suit the requirements of a water system, emphasising a balanced damping application rather than putting undue strain on Davey’s Horizontal Multistage water pump. This further prevents needless pressure drops or surges that could harm pipes.
Resource and energy conservation: By using the Horizontal Multistage water pump with the pressure switch variation, natural resources like our raw water source, which is provided by Air Selangor or a comparable ration-sourcing body, can be preserved as much as feasible. This happens only because the strength of h2o flow rate is welcome only when purposefully needed, ultimately reducing wear and tear of the electropump as well as maintaining a longer lifespan.

Pressure Tank
The pressure tank itself is the final component that may be added to Davey’s Horizontal Multistage water pump. Since water can be retained within to lessen the activation and deactivation arrangement, it is unquestionably crucial to the ongoing frequency of use for all kinds of booster pumps.
This flexible covering, which has a simulated diaphragm, helps keep air and water apart inside the pressure tank. This is crucial because if liquid and oxygen interact, cavitation may occur, which might result in immediate damage that could be lethal to the surrounding area.
This operates internally by storing water to force against the diaphragm, which compresses the atmosphere of air above it. The Horizontal Multistage water pump will automatically stop when the reservoir exceeds the threshold. And the limited air movement would simply force the water out through a running pipe, shower head, or toilet system. Davey’s Horizontal Multistage centrifugal pump would alternate between cut-out and cut-in pressure gradually and steadily until it reached its bare minimum pressure, at which point it would reset to resume refilling.
Certification
Davey has gathered the required accreditations required for a market-entry setup in order to continue expand into various territorial regimes and continents, such as Malaysia in Southeast Asia. As a result, the Horizontal Multistage centrifugal pump underwent testing and received top-notch certifications. These certifications are limited to the usage of home appliances, the assessment of the water pump’s suitability for rationing, and/or the observation and rigorous testing of the pump within the manufacturing production line to ascertain its consistent quality.
SGS Approved: Davey’s HM water pump bears a safe range of electricity safety standards within domestic application thanks to the inspection conducted by Société Générale de Surveillance. Testing for inadvertent shock, possible centrifugal pump shorting, potential fire generation, and even confirming if the horizontal multi-stage is appropriately enclosed and contained are instances of retorts to the definition of electrical protection.
The Horizontal Multistage pump complies with European Standards, which are the authoritative regulatory body for harmonising technical mandates throughout Europe. This ensures security, excellence in grading, interoperability, a greener conscience, and trade access to Western soil. Another way that this water pump helps to improve civilisation is through technological improvement.
In order to achieve mutual recognition agreements (MRAs) for broader trade access, Davey has adhered to the International Electrotechnical Commission (IEC), a global authority on voltage and electronic-based technology that was established in 1906.
Australian Standards: The main benefit of gaining Davey’s home ground’s trust is that an independent, non-profit regulation has concluded the recognition of the Horizontal Multistage pump and its diesel motor version for electric-powered safety clearance.
The Australian Standard AS4020:2005 states that all materials used or applied in the construction of water systems, including the Horizontal Multistage pump, must remain safe when they come into contact with drinking water. This certified byproduct is important for manufacturers and suppliers like Davey to establish a guarantee that liquids run by their water pumps are intrinsically safe to consume. This electropump is tested using a variety of points of reference and testing techniques on the pipes, attachments, coating, and any related materials.
New Zealand Standards: Another Oceania region consumer safety certification that Davey has achieved for its exporting reasonableness credentials.
ISO 9001: A quality management system that distinguishes between higher tier alignment and the typical pump manufacturer. As officials examined our routine in the ongoing pursuit of improvement, Davey’s Horizontal Multistage electropump was able to secure this. They also discovered that our products were consistent from batch to batch across the supply chain distribution.
ISO 14001: The environmentally conscious methodology used in the production of horizontal multistage pumps for a better world and a more sustainable future. The ISO 14001 stands for the introduction of recycling practices throughout Davey’s assembly, the shutting off of superfluous lights during specific periods of inactivity, the replacement of outdated bulbs with light-emitting diodes during the pump formation, and the appropriate route dividing for a quicker and farther-closing delivery of Davey Malaysia’s products.
Overall, obtaining these accreditations has increased Davey’s credibility and reputation while also increasing customer satisfaction with the Horizontal Multistage electropump’s frequent use.
TEFC Motor
For every period of daily use, Davey’s Horizontal Multistage pump runs at full strength and a consistent water pressure pace. Regardless of the current utility period, this is as simple as any centrifugal pump gets.
Easy Setup: This horizontal multistage electropump’s simplicity lies in the fact that it can be easily installed by placing it directly beneath the water tank, connecting it in, and then allowing it to run. People who desire a direct water pump arrangement in their homes or businesses don’t need to take any further procedures.
The rear end of the Davey’s Horizontal Multistage pump displays the branded yellow coating, which serves as a barrier against rust and external wear. The crucial motor that rotates the pump’s shaft to apply pressure within the house is housed inside. Davey Malaysia has a showcase model called the HM series that can be used for elaborate presentation.

More than 200 starts per hour: A stable and robust number of starts the engine can achieve without experiencing mechanical failure is one of the key features that lures Davey’s Horizontal Multistage pump to its fable. This hourly cycle significantly outperforms many of our rivals in the centrifugal pump market. However, only some Hotizontal Multistage pump versions are capable of more than 200 starts per hour.
Reliable and Proven: The fact that all horizontal multistage pumps have been on the market for a considerable amount of time indicates that the mechanical engineering concepts required to create this device are dependable and unquestionably proven. Therefore, if this centrifugal pump needs to be fixed at all, there is an abundance of readily available research and development, a supportive culture, and a large variety of conveniently accessible spare parts.
Cost-effective: With sufficient components and an electrical motor pump with a single direct-to-access force of gush needed for a good shower, irrigation, or cleaning, the already advanced engine electrotechnology requires no additional tuning, and Davey Malaysia has a strong supply chain that makes it simple to assemble the Horizontal Multistage water pump in bulk, resulting in a cost-effective product that is currently widely used worldwide.
Davey HM60-08T Domestic Horizontal Multistage Pump Installation
The Davey Water Products HM60-08T is designed to provide stable and reliable water pressure performance for residential homes, small garden irrigation systems and light domestic water transfer applications. The HM60-08T from Davey’s Horizontal Multistage (HM) Series is recommended for single and double-storey residential applications where multiple outlets need to be supplied with constant water pressure at the same time.
(A Davey Infographic For Housing Pump Selection. HM60-08T can be said to be similar with DD60 of DynaDrive without the inverter.)
A typical calculation of a household water system usually considers several factors, for example, the number of bathrooms, the number of water outlets, length of pipes, elevation and the simultaneous demand for water usage. With these requirements in mind, the HM60-08T is targeted at the practical medium household, where balanced water pressure and efficient water delivery are essential.
HM60-08T applications include:
- Shared bathroom usage
- Water supply, kitchen, laundry
- Irrigation of gardens
- Boost internal pressure
- Rainwater transfer systems
The HM60-08T uses a stainless steel multistage hydraulic assembly and Torrium2 controller system to automatically operate the pump, providing smooth and consistent water pressure throughout the home. Its compact horizontal design also facilitates installation in residential environments with limited space.
The HM60-08T is a perfect option for homes with moderate water usage needs, providing a good mix of water pressure performance, energy efficiency, compact size and long-term reliability.
Inlet Size

A suction port is visible in the front portion of Davey’s horizontal multistage pump. Because it is composed of 304 stainless steel, the alloy is further polished to produce a sheen that is resistant to rust. The suction port has a 1.25-inch (or even 1.5-inch) size that can still be linked with a connection, depending on the pump model used.
Any water pump’s suction inlet’s primary function is to let the right kind of fluid enter and be transferred into the system for further pressurisation. Depending on the centrifugal pump being used, this situation changes.
For instance, a sump pump’s input contains a grinder and a filter-strainer to remove trapped debris, allowing sewage to be fed into the water system’s engine. This helps reduce flooding and/or waste management for ethical and hygienic reasons. As a home pressure system, Davey’s Horizontal Multistage pump’s primary function is to draw in a clean water source exclusively.
Unidirectional Flow: The horizontal multistage water pump, which has a dynamic structure to maintain flow rate, aids in directing the aquatic fluids unidirectionally into the impeller section while the electrical motor pulls in water through a pressure differential.
This electropump comes in a variety of models with varying intake sizes. This is to make sure that the pump’s output is equal to the housing’s piping system because water overflows easily. However, a connector can be utilised to bridge and remedy the dimensional gap differences if the pipe’s diameter is discovered to be significantly less (or larger) than the Horizontal Multistage pump’s input itself.
The input port suction seen throughout Davey’s HM series is summarised in the table below:
| 230V ± 10% Single Phase Models | ||
| Product Code | Ports | |
| Suction BSP | Discharge BSP | |
| HM60-08T | 1¼” F | 1″ M |
This phenomenon manifests itself on its own as a necessary net positive suction head (NPSH) when any of Davey’s Horizontal Multistage water pumps reach full water suction and there are no air pockets in the water system.
Reduced Friction: This centrifugal pump’s larger input sizes result in a higher flow rate since the water flows through it much more readily. This is yet another instance in which self-priming accelerates significantly.
Volute
The volute, which seems to be cylindrical while maintaining the integrity of several staging bodies (diffuser and impellers), is actually spiral in shape on the inside and is constructed using a durable and polished composite metal combination. There are four reasons to apply this for the horizontal multistage water pump:
As water swirls and passes through each stage of the impeller before continuously exiting through the outlet, it helps the discharge fluids’ excessive strength. The electropump’s thoughtfully designed volute reduces turbulence and maximises flow rate overall.
Protective barrier: The durability of the otherworldly volute casing keeps out any exterior residue or even litter that would interfere with the Horizontal Multistage pump’s clean water supply or otherwise harm the current setup.

The volute enclosure is made of sturdy 304 stainless steel. This contains the interior components that are divided into chambers of staging bodies, such as the diffuser, impeller, and mechanical seal. This photo was taken at the Davey’s Horizontal Multistage pump showroom.
Interchanging Energy States: The water is gradually forced away from the center and centrifugally resisted to the outer alloy walls before being released onto the Horizontal Multistage pump’s outlet. This process starts with the motor developing a suction force and moves towards the interior area where fixed impellers impart its kinetic energy. As the volute chamber fills throughout this process, this change in energy transforms from kinetic to pressure, decreasing speed while simultaneously increasing water pressure. This phenomenon is consistent with the scientific law and observation of Bernoulli’s principle.
Self-Priming Affirmation: The Horizon Multistage water pump will eventually be devoid of any air gap that permits self-priming as the volute body gets internally moistened and hydrated. If not, destructive cavitation could be caused by trapped air surging into the impeller as it spins alongside water.
Impellers And Diffusers

A close-up of the staging body. This was captured before to being installed in a horizontal multistage pump on the assembly line. It was discovered to be made of sturdy 304 stainless steel, an essential alloy grade for use in damp environments. There is an open hole in the center that is intended to fit onto the mechanical shaft where the rotor would push to spin the impellers for the necessary water pressure while keeping the closed impeller and diffuser in place.
Impellers and diffusers are compartmentalised within the volute chambers, arranged in a systematic manner as staging bodies. These staging bodies, sometimes referred to as the protective bracket, play a crucial function in keeping these devices in place and preventing them from coming free inside the Horizontal Multistage water pump when operation and revolutions start.
Each staging body room would create an increase in pressure required for the best flowing tap use, showering or applying across other everyday necessities as water travels from the first phase to the next.
Closed Impeller Design
In order to reduce the thrust load, closed impellers are fitted on the shaft to optimise fluid handling while the rotor is being driven.
Improved Performance: Because its vane is double-walled (front and rear), the liquids inside are directed suitably to a smooth and dependable output as they exit in centrifugal force to the outlet, resulting in an electropump with exceptional hydraulic performance.
Cavitation-Apparatus Prevention: The impellor’s protective barriers make the Horizontal Multistage water pump much less vulnerable to the formation and collapse of air bubbles inside the water, thereby preventing additional damage to the pump.
Longer Service Life: When thrust load is reduced, bearing life, usage frequency, and shafting expenses are all reduced, making the horizontal multistage centrifugal pump more durable.
Because the impeller and diffuser are constantly dampened with large volumes of fluid, stainless steel material is employed to avoid deterioration while retaining strong endurance during the cycles of the horizontal multistage water pump’s operation.

Smooth Surface: This section is polished as smoothly as possible before the impeller is inserted into the electropump in order to minimise surface tension, which results in the least amount of friction and turbulence. In Davey’s Horizontal Multistage pump, this technique results in increased fluid movement efficiency while reducing needless energy loss through power usage (measured in kilowatts).
Thermodynamics Stability: In situations where the temperature of the gush supply varies, the impeller made of higher-grade stainless-steel material performs steadily, with its mechanical characteristics barely contracting or expanding. This makes it possible to suck hot and cold clean water into the horizontal multistage pump in a variety of ways.
Generator Protection With Mechanical Seal And Backplate

The backplate, the circlip, and a mechanical seal are visible in the rear sections. These are fitted onto the shaft as a last line of defence against water seeping into the motor portion of Davey’s Horizontal Multistage centrifugal pump since they are all equally protected by SUS304 metallic alloy.
The most important factor in determining whether Davey’s Horizontal Multistage pump would continue to function is the part when electrical engineering deviates from its mechanical field application. A backplate and a mechanical seal component are integrated into the engine to prevent any possible splash from entering the core motor, since the engine’s electrotechnology components must stay away from water contact to prevent short circuiting. This is done by sealing the remaining gaps with a gasket or washer.
In the same instance, water that spiralled outward would be distributed toward the discharge outlet, using the centrifugal pump to achieve the desired water supply. In order to prevent Davey’s Horizontal Multistage pump from tilting or going out of alignment once rotation starts, the backplate and mechanical seal are also installed to maintain the shaft in a stationary position.
To guarantee that the mechanical seal of the Horizontal Multistage water pump is continuously enclosed, a circlip can be found inside the mechanical seal and before the backplate, where spinning stress is passed onto it. However, this circlip—also referred to as a clip spring in the official Davey Water Products handbook—is entirely absent for the HM80 and HM150 series alone.
O-Ring With Vibration-Absorbing Spacers
In order to guarantee a tight fit and stop further latent leakage from emerging, the Horizontal Multistage electropump is coupled with an O-ring whenever feasible when each core piece joins from one segment to another inside. This hydrocarbon, which is moulded using EPDM (ethylene propylene diene monomer) rubber, outperforms neoprene in terms of increased warmth and is ideal because it works well with Davey’s Horizontal Multistage water pump for temperature stability. Usually, the volute case has a large number of these O-rings.
In order to prevent the revolving pieces in this horizontal multistage water pump from grinding against one another, spacers are inserted. Additionally, when the HM electropump starts operating, its placement helps the mechanical bearings stay precisely in place while preventing any particular parts from being excessively compressed.

Absorbing Vibrations: These spacers in the horizontal multistage centrifugal pump function as pseudo-vibration absorbents to reduce any needless machine stress and temper further rigidity.
An enlarged image of an O-ring being fitted into the joint compartments of Davey pumps. The rubber, which is composed of ethylene propylene diene monomer, was selected due to its adaptable resistance to water pumps operating at higher temperatures.
Similarly, every internal component of this water pump, including the impellers, mechanical seal, spacers, circlip, and even its volute casing, is built of sturdy stainless steel 304 (or SUS304) to ensure uniform hardness. Only the motor-connected shaft, which is constructed with the durable SUS316, is intended to convey rotating power severely.
