Davey’s TotalFlo water pump range is structured into three primary sub-models, each engineered for a distinct application. These comprise the jet pump variant, a multistage centrifugal pump optimized for mid-sized residential use, and the sump pump, specifically designed for wastewater handling and flood management.
The compiled product codes reflect the complete lineup of TotalFlo water pumps available in Malaysia at this moment. Accordingly, all official models are confined to these listed electropumps and their corresponding serial numbers—no additional variations exist beyond this range.
Method of Identification
Davey Water Products applies a standardized identification system across its product range—an essential element in supporting supply chains for over 90 years. This framework ensures that every centrifugal pump and water treatment product can be accurately identified and efficiently tracked.
For TotalFlo water pumps, each model is assigned a serial code following a structured format:
1) An abbreviation of the product name.
2) The pump’s flow rate (in litres per minute).
3) A letter denoting the pump type or configuration.
4) 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
– “50” indicates a flow rate of 50 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 convention enables users and suppliers to quickly interpret the key specifications of each pump at a glance.
Within the alphabetical component of the code, specific letters denote the pump type. For instance, “S” indicates a TotalFlo sump pump, while “MS” refers to a multistage configuration.
Each pump is assigned a unique code based on this fixed format, ensuring precise model identification. This is particularly valuable during maintenance or repairs, as Davey Malaysia’s retailers can efficiently reference the correct components required for servicing.
Beyond identification, these serial codes also facilitate tracking across the distribution and delivery network. Internally, they support accurate product selection and processing for purchase orders. This standardized system is implemented across all Davey offices, where inventory is managed in-house and organized using these serial numbers to ensure consistent, efficient product handling.

Tangki Tekanan
The TF50J-18 can work on its own, but putting it with a pressure tank has a number of benefits, especially for homes where water use changes a lot.
Less Pump Cycling: The pressure tank stores pressurised water, which means the pump does not have to start and stop as often. This helps the pump last longer by reducing wear and tear on it. It also stops water hammer, which is a sudden increase in pressure that can break plumbing and pump parts.
Keeps Water Pressure Steady: The tank has a diaphragm or bladder inside it that keeps the pressure steady, so consumers get smoother and more constant water flow even when demand is high. This is especially helpful for homes with more than one bathroom or outlet.
Makes Energy Use More Efficient: The system uses less electricity because it does not have to turn on the pump as often. This not only lowers energy costs, but it also lowers the carbon impact over time, making the household more eco-friendly.
Tank Capacity: The TF50J-18 can hold a pressure tank that is up to 8 litres (2.11 gallons) in capacity. The tank holds water and lets it out when needed without turning on the pump every time, which makes sure that everything runs smoothly and efficiently.

ISO 14001 shows that Davey cares about the environment. The accreditation proves that the pump’s manufacturing is environmentally friendly, with things like using resources wisely and cutting down on waste.
Electric Motor
The TEFC motor (totally-enclosed, fan-cooled engine) at the heart of the TF50J-18 is strong and dependable. It was made to keep the water pressure steady for home use.
Output of the motor: 0.6 kW (0.8 HP)
Power Supply: 220-240V single-phase
Built-in Safety: It has thermal overload protection to keep the motor from overheating, which extends its life and makes sure it can be used safely every day.
This motor works well all the time, therefore it’s good for medium to big homes that need consistent water flow to several outlets.
Easy to Set Up: All you have to do to set it up is plug it into a regular electrical socket with a 3-pin plug. Once you turn it on, the pump is ready to use right away, with no complicated wiring needed.
Self-Priming Capability: The motor is made to automatically get rid of air that gets stuck in the suction line. As it fills with water, it may slowly build up pressure. This feature works best when it is put below a water tank, which makes the suction work better and the machine run more smoothly.
The engine is made to work in homes and makes very little noise while still providing the pressure needed for home use. It’s a good choice for people who want good performance without too much noise.
The TotalFlo motor from Davey uses a well-known centrifugal principle to make water pressure work well. Instead of using experimental technologies that make the design too complicated, Davey concentrates on tried-and-true engineering that maximises reliability and output.
Infographic For Household Pump Selection Guide
The infographic below presents Davey’s complete home pressure system for its range of centrifugal pumps. It has been meticulously developed by Davey Malaysia’s in-house engineers, incorporating typical piping layouts alongside the number of taps and showerheads in a household. These variables are translated into a practical reference chart to guide users in selecting the most suitable pump for their home.
The system overview features several key pump options, including Davey’s DynaDrive, the horizontal multistage pump, and the TotalFlo range. Each model is aligned with varying household sizes and water usage requirements, simplifying the process of choosing the appropriate configuration for consistent and reliable water pressure.
The TotalFlo range comprises several models designed to accommodate varying household sizes and water usage demands, including the TF40, TF50, and TF117.
For smaller homes—such as single-storey residences with up to two showers and approximately four taps—the TF40 or TF50 is typically sufficient to deliver consistent water pressure.
As demand increases, particularly in homes with up to four bathrooms and around seven taps, the TF117 becomes a more appropriate choice. This generally applies to larger properties, including one-and-a-half or double-storey homes, where higher flow capacity is required to maintain stable performance across multiple outlets.
Suction Inlet
The TF50J-18 has a 1-inch (25.4 mm) BSP female suction input that was chosen for larger pumps to help them move more water and prime faster. It is made of SUS304 stainless steel, which is very resistant to rusting that happens when it is in contact with clean or slightly dirty water for a long time. The polished surface also makes it less likely to rust and makes it last longer.
The bigger inlet makes it easier to take in water from overhead tanks or mains. Its size makes it easier to self-prime, which cuts down on downtime during starting. A plastic cap is already on the item to keep dust and dirt out during delivery and installation. The entrance is made to pull in clean water easily and without leaving any air spaces.
The pump is located below the water tank, which gives it a naturally supported Net Positive Suction Head (NPSHr). This makes the suction more reliable and lowers the possibility of cavitation. To keep the impellers working at their best and make sure that water flows to them without interruption, the suction line must be installed correctly.
| Inlet and Outlet Information | |
| Inlet Size | 1-inch (25.4 mm) F |
| Outlet Size | For all home pressure systems: 1-inch BSP M |
| Max. Head | 41m (134.51 ft) |
Volute
The volute in the TF50J-18 is an important device that is designed to safeguard internal parts while efficiently directing water from the impellers to the output. The volute is made of SUS304 stainless steel, which is very strong and resistant to rust. This is vital for residences that get their water from multiple municipal sources, including SYABAS or Penang Water Supply, which may have small amounts of minerals in them.
The curvature of the interior spiral casing is designed to let water swirl about in a way that is best for it. The water moves along the volute’s curved route, where its speed turns into pressure with very little turbulence. The volute shell also protects the pump’s internal parts from damage from outside forces like sand, debris, or other things that could get inside. A clean, shiny finish looks good and is easy to keep clean.
This construction makes sure that the product will endure a long time and work well all the time, especially in places where it gets wet, dirty, or worn down.
Closed Impeller Design And Diffuser
The TF50J-18 pump has a four-stage pumping system with stainless steel impellers and diffusers that gradually increase the water pressure. This makes it great for people who want stable pressure and don’t want to have to do any maintenance.
Impellers: Closed-type stainless steel impellers are precision-machined to get the best centrifugal motion. These make the water move quickly with little energy loss, even when they are running all the time.
Diffusers: Located after each impeller, diffusers turn the speed of the water into pressure very well. Their staggered arrangement makes sure that each cycle builds on the one before it, which keeps the outlet pressure strong and steady.
Performance: The pump’s multi-impeller design lets it handle the needs of multi-story homes, garden irrigation, or using water from more than one outlet at the same time.
Durability and Flow: The stainless-steel construction doesn’t wear down from friction or water exposure, and the smooth surface finish lowers internal drag and helps the machine run quietly and use less energy.
Gasket, Backplate, and Mechanical Seal
To keep the TF50J-18’s motor and internal parts safe, high-quality sealing parts are built in to keep leaks from happening and the structure from falling apart.
Mechanical Seal: This seal is put in place along the shaft near the motor housing. It protects water from getting into the motor chamber, which makes sure that the electrical parts work safely and lowers the chance of failure due to moisture getting in.
Rubber Gasket: The gasket is located between the volute, backplate, and motor of the pump. It keeps the pump sealed tightly and absorbs vibration, which lowers the stress on the pump while it is running. Reduces noise by limiting direct contact between metals, which makes the pump quieter.
Backplate: This is the last line of defence against backflow or splashes getting to the motor. It holds up all the moving parts and helps keep the pump’s structure stable.
The picture below depicts some of the most important internal parts of the TF50J-18 centrifugal pump. These sections, like the suction intake, volute casing mechanical seals, and gasket, are all designed to work best for household water pressure.
O-Ring, Spacer, And Washer
The TotalFlo TF50J-18 water pump has carefully designed sealing parts that keep it airtight and strong. The O-rings are one of the most important parts. They are carefully placed at different connecting locations throughout the pump.
These O-rings are made of EPDM (ethylene propylene diene monomer), a synthetic rubber that works well and is very resistant to heat, wear, and chemicals. EPDM is better than other materials like neoprene because it can handle higher temperatures. This is crucial when pumps are running for a long time or while handling thick, slurry-like liquids. These kinds of conditions can cause a lot of heat to build up inside, yet EPDM stays flexible and strong enough to seal even in those tough situations.
These O-rings help keep the system running smoothly by making airtight and watertight seals that stop leaks from happening inside the system. To keep the pump working well and reliably for a long time, you need to check the O-rings regularly and replace them as they wear out.
Spacer: A spacer is used to maintain a fixed distance between two parts inside the pump, such as the impeller, shaft, or housing. This ensures the rotating parts do not rub against stationary parts, where proper spacing helps reduce friction, prevents wear, and maintains efficient water flow and pressure.
Washer: A washer is a thin disc placed under a bolt or nut. In a water pump, washers help distribute load evenly when parts are tightened, preventing damage to surfaces. They also help reduce vibration, maintain tight sealing, and in some cases act as a barrier to prevent loosening due to constant pump movement.
In short, spacers control position and alignment, while washers improve stability, sealing, and durability.
