Davey’s TotalFlo water pump range can be grouped into three main sub-models, each designed for a specific application. These include the jet pump variant, a multistage centrifugal pump suited for mid-sized residential use, and the sump pump, which is primarily intended for wastewater handling and flood management.
The compiled product codes represent the full lineup of TotalFlo water pumps available both in Malaysia and worldwide. As such, any official models are limited to these listed electropumps and their corresponding serial numbers—no additional variations exist outside this range.
Method of Identification
Davey Water Products uses a consistent identification system across its product range—a key part of how it has supported supply chains for over 90 years. This system ensures that every centrifugal pump and water treatment product can be easily identified and tracked.
For TotalFlo water pumps, each model is assigned a serial code based on a structured format:
- An abbreviation of the product name
- The pump’s flow rate (in litres per minute)
- A letter indicating the pump type or configuration
- The cut-in pressure, expressed in bar and multiplied by 10
For example, consider the model TF40J-18. In this code:
– “TF” represents the TotalFlo product line
– “40” indicates a flow rate of 40 litres per minute (L/min)
– “J” identifies the pump as a jet type
– “18” corresponds to a cut-in pressure of 1.8 bar (or 180 kPa)
This structured naming approach allows users and suppliers to quickly understand the key specifications of each pump at a glance.
In the alphabetical portion of the code, specific letters indicate the pump type. For example, “S” denotes a TotalFlo sump pump, while “MS” refers to a multistage configuration.
Each pump is assigned a unique code following this fixed format, making it easy to identify the exact model. This is especially useful during maintenance or repairs, as Davey Malaysia’s retailers can quickly reference the correct components needed for servicing.
Beyond identification, these serial codes also support tracking throughout the distribution and delivery network. Internally, they are used to ensure the correct centrifugal pump is selected and processed for purchase orders. This standardized system is applied across all Davey offices, where inventory is managed in-house and organized using these serial numbers to enable accurate and efficient product handling.
Attachment
Pressure Tank
You can add a pressure tank to the TotalFlo water pump as an accessory. To stop the pump from cycling all the time, you can install up to 8 litres (2.11 gallons) in the case of Davey.
Preventing Pump Cycling: The pressure tank is a place where aquatic rations are held and is very important to any water system because it stops the pump from starting and stopping again and again, which can break Davey’s TotalFlo pump. Also, the phenomenon of water hammer is stopped when the surge of hydration is released from reserve when the pipes are opened. This puts needless stress on the TotalFlo centrifugal pump and damages the water supply network as a whole.
The pressure tank has an inner diaphragm (also called a rubber sheet or a bladder) that separates the top layer of pure air from the bottom layer of water. As the water is stored, it pushes up against the artificial diaphragm, which compresses the air above it. This creates the tension of pressurised water as needed, instead of having to rely on the TotalFlo water pump all the time.
Regime For Environmentalism: By lowering the amount of time Davey’s TotalFlo water pump needs to be turned on and off, greenhouse gas emissions are reduced, which means less energy is used and less carbon is produced over a set period of time.
Certification
Davey has received a number of consumer and manufacturing-related accreditations for the TotalFlo water pump. These show that the safety of end users is a top priority and that the company has earned the trust of customers, which is a crucial element when choosing a booster pump.
In addition, Davey Water Products must get the right licenses from different regional laws. These are also acceptable icons that are needed to export the TotalFlo centrifugal pump to other continents and territories.
SGS Approved: The Société Générale de Surveillance’s strict test of electrical protection to find any problems with Davey’s TotalFlo water pump as a home appliance test, where the entryway is cleared to show that the pump motor cables are properly insulated to stop electrocution and other galvanic hazards while in use.
European Standards (ES): The technical uniformity that was first introduced and centralised among the European organisations for goods, services, and procedures in adherence to match the people’s welfare, the quality of production, eco-friendliness, and the necessary tabulation as well as data-backed findings of performance has been met by Davey’s TotalFlo water pump. European Standards (ES): The technical uniformity that was first introduced and centralised among the European organisations for goods, services, and procedures in adherence to match the people’s welfare, the quality of production, eco-friendliness, and the necessary tabulation as well as data-backed findings of performance has been met by Davey’s TotalFlo water pump. Getting this certification makes it possible for Davey’s electropumps and other water-related products to be sold and utilised in Europe.
One important reason for following European Standards is that they recognise the potential for innovations to function together. As the TotalFlo centrifugal pump receives this certification, it shows that it can work with inventions from other companies. For example, you can connect a pressure switch from another company to the TotalFlo pump to treat your water at home. There is also a “CE” label on the product to show that it meets all the important rules set by the European Union.
The International Electrotechnical Commission (IEC) is in charge of all voltaic causes, computer work, and related progress. Davey’s TotalFlo water pump is a part of that regulation. This is mostly the part of the pump’s engine that makes it work, and it needs to be powered by electricity, which is what the IEC is all about. Getting this accreditation means that Davey is accepted and follows the rules everywhere, which makes it easier for TotalFlo water pump distributors to find manufacturers of Mutual Recognition Arrangements (MRAs).
Standards Australia (AS): A voluntary standard created by a non-profit group in the home country of Davey Water Products. Australian law often refers to this independent institution as the only way for people in Australia to sell things, such the TotalFlo pump. The Australian Standard is the most important point of reference for a non-governmental organization, which is why Davey is glad to follow its plan.
AS4020:2005: Looking at all the details about any product or solution that comes into contact with water, it has been studied and found that Davey’s TotalFlo water pump does not pose any risk to human health, no matter how small the incident. There were no more changes to the reservoir’s status, and this electric pump was given the AS4020:2005 sub-clause acknowledgement. The formal inspection checks numerous aspects of the TotalFlo water pump, such as the pipes, fittings, coatings, seals, and even the pressure tank (if it is attached).
Standards New Zealand: Standards New Zealand is the official body in New Zealand that sets, reports on, and protects quality standards for all industrial use. This includes the working principle of centrifugal pumps in the mechanical engineering field. The name is similar to that of the Australian Standards. This is important for Davey to meet in order to move into another area of agriculture, such as deep wells, irrigation, swimming pool covering, fountain motors, and other speciality water pump uses.
ISO 9001: The most important framework that many manufacturers use, the 9001 clause of the International Standard of Organisation provides guidance for making Davey’s TotalFlo centrifugal pumps. It sets standards for how each step should be documented in the drawing of production blueprints, which helps ensure that the supply chain is as consistent as it should be. Also, the belief that constant advancements will lead to a distinct proposition level of pump products is stressed.
ISO 14001: The 14001 section of ISO is about how to run Davey’s TotalFlo pump construction in a way that is good for the environment. The honour came to the conclusion that the manufacturing procedures take into account energy use, the moral littering of byproducts during the making of the electropump, the necessary steps for pollution management, and the amount of resources that were used. The labelled accreditation is a big step toward a brighter future, as are the actions Davey Malaysia has made to use it.
Constant Pressure Motor Pump
Design experts have developed this edition of the Home Pressure System series to include a basic motor that travels at a constant pace. This is because they want to make a water pump that is worth the cost for tiny homes.
The engine of the TotalFlo water pump is made for small homes and generates the right amount of pressure with a low noise level.
Easy to Install: Just put the three-pin plug into the wall socket, and the TotalFlo electropump is always ready to run its cycle when the switch is flipped open.
Self-Priming: The priming motor can get rid of trapped air on its own, and its suction port will slowly but surely get completely wet to create a stable pressure state. This can only happen if Davey’s TotalFlo water pump is placed under the water tank so that it can suck in water all the time. In this setup, there is a greater likelihood that a net positive suction head (NPSHr) will happen.

Demonstrated Technology: Davey’s TotalFlo water pump has a motor that is backed by scientific proof to swirl water centrifugally. This means that you don’t need to spin the wheels because you can use what already works.
Infographic For Household Pump Selection Guide
The infographic below illustrates Davey’s complete home pressure system for its range of centrifugal pumps. It has been carefully developed by Davey Malaysia’s in-house engineers, taking into account typical piping layouts, as well as the number of taps and showerheads in a household. These factors are translated into a practical reference chart to help users select the most suitable pump for their home.
The system overview includes several key pump options, such as Davey’s DynaDrive, the horizontal multistage pump, and the TotalFlo range. Each model is matched to different household sizes and water usage needs, making it easier to choose the right configuration for consistent and reliable water pressure.
The TotalFlo range offers several models to suit different household sizes and water demands, including the TF40, TF50, and TF117.
For smaller homes—such as a single-storey dwelling with up to 2 showers and around 4 taps—the TF40 or TF50 is generally sufficient to provide consistent water pressure.
As water usage increases, such as in homes with up to 4 bathrooms and approximately 7 taps, the TF117 becomes a more suitable option. This typically applies to larger residences, including one-and-a-half or double-storey homes, where higher flow capacity is needed to maintain stable performance across multiple outlets.
Suction Inlet
The TF40J-18 water pump features an input port that is 1 inch (25.4mm) wide.
With its main job to draw and direct clean water, it would flow through the impeller within where it is then pressurised.
Davey’s TotalFlo of the sump pump sorting, on the other hand, is meant to pull in wastewater or even floods that have built up and stopped moving in a sump pit. This is then sent somewhere else to keep the pump from getting clogged.
The TotalFlo water pump is made of SUS304-grade stainless steel alloy, which is strong and looks nice after polishing. The pump’s body needs to be very resistant to corrosion because it gets splashed and soaked with water from Air Selangor (SYABAS), the Penang Water Supply Corporation, or other state-level ration providers. It can even get dirty water from debris and mud.
Under a Water Tank: The location of Davey’s TotalFlo water pump should stay the same. It should be close to and below the water tank. This is done to meet the Net Positive Suction Head (NPSHr), which means that a lot of filtered water flows into the suction intake to fill the air gap in the electropump. As the centrifugal pump works, it removes more and more air, exactly like the TotalFlo’s inner dampening keeps happening, which helps to stop cavitation. The whole hydraulic circuit makes it so that the water pressure with this pump stays almost the same.
One-Directional Flow: The motor of Davey’s TotalFlo water pump provides a suction force that pulls in water, and the fluid input only goes in one way.
When Davey’s TotalFlo water pump is delivered, a plastic cap is put on the inlet to keep the application safe. This is to stop fine dust or other outside sources from getting in and destroying the pump’s internal parts, which would stop it from working.
Volute
The volute covers protects and holds the internal parts in place. The combined metallic materials with carbon make Davey’s TotalFlo water pump resistant to rust.
The graded metal assignment SUS304 is used to improve the suction inlet and other internal parts of the electropump.
The spiral shape is extended out over a cylindrical container. When dilution gets pulled in, the water is sent in a whirling motion that presses against the walls from the inside before being directed to the discharge outlet of the centrifugal pump.
The volute and the rest of the housing work together to increase the flow rate to its best level, which lets a lot of pressure out.
The TotalFlo pump’s volute casing. It is also composed of 304 quality stainless steel, which makes it strong enough to keep things like trash, sand, and other things from getting inside and damaging the internal parts. Light is bouncing off the volute, showing that it’s shiny because it was polished for looks.
External Protection: The volute casing’s most important job is to keep outside forces and possible junk from getting into Davey’s TotalFlo pump. It only works with clean water, therefore any trash, sand, dirt, or other things that become stuck in the water system could break it.
Self-Priming Guidance: The volute can only store so much water at a time. Once it is full and all the air is released, the TotalFlo electric pump would keep an internal hoover that constantly pulls in water. This is the ideal primed state that all water pumps want to be in.
Closed Impeller Design And Diffuser
All of the TotalFlo water pumps for homes have a closed impeller, except for the sewage pump, which has a semi-open impeller. This design allows for better water movement efficiency, which means that the pump has stronger end pressure, a higher flow rate, and less energy loss when it is running.
A closed impeller can break into two parts: the vane, where liquids are whirled around in a circular motion, and the cover or shroud that surrounds the impeller and diffuser. These are sealed into a chamber or even several stages (if it’s a multi-stage variety) inside any TotalFlo water pump.
Less Damage: Davey’s TotalFlo water pumps are less likely to get damaged by things like rocks and dirt since they are protected by a closing cover. This is especially true when the sump pump is used to get rid of sludge.
Lessening Cavitation: The sealing mechanism helps keep cavitation from happening, which makes the TotalFlo electropump last even longer.
Smoothened: Since here is where most of the water flows through, every part of the closed impeller is polished to its smoothest surface to cut down on friction when it touches something. here improves the water flow and also cuts down on Davey’s TotalFlo pump’s unneeded power use.
Improved Thermodynamics Performance: The closed impeller makes the flow more organised. This is because entropy (the waste of energy that happens when things move randomly) is lower, which means higher performance.
Gasket, Backplate, And Mechanical Seal
There should be a barrier to keep Davey’s TotalFlo water pump (and the user) safe from any unnecessary water, spills, or other forms of dampness that could damage the machine. This is especially important in the back end where the motor is. The backplate is the last line of defence that protects the electrotechnology from damage and lets water flow out of the centrifugal pump’s discharge exit.
First, you need to screw a rubber gasket into place. This will hold all of the other parts of the pump (the volute, rotating shaft, backplate, and even the motor) firmly in place. The gasket does the following:
Vibration Absorption: One of its benefits is that it can absorb too much vibration, which reduces mechanical wear and stress that isn’t needed. This is one of the things that helps the TotalFlo water pump last longer.
Noise Reduction: This electropump stops sound from getting through by preventing contact between different alloys.
The central part of Davey’s TotalFlo water pump that was taken apart for the audit. There is a lengthy shaft where the impellers are attached. The mechanical seal and backplate on the back keep the parts in place and keep the engine from becoming wet from the water flow.
There is a mechanical seal in front of the backplate and on the shaft. Its main job is to keep water from leaking straight into the engine of the TotalFlo pump.
O-Ring, Spacers And Washer
The O-ring application in EPDM (ethylene propylene diene monomer) is airtight and watertight, and it fits into different portions of Davey’s TotalFlo water pump in different sizes.
EPDM is chosen over neoprene because it can handle high temperatures, which can happen when pumps are running for a long time and when they are removing viscous liquids (sticky slurry can make water pumps work less efficiently, which creates even more heat).
This is the last and most important layer of protection. The washer is finally employed and placed in front of the mechanical seal element to create another tight barrier that keeps water from getting in. The washer also shows how the load is spread out since it stops grinding and lets the activity of other bits run at the same time.
