Davey Water Products has implemented a distinct and systematic product identification method across its entire range, including centrifugal pumps and water treatment systems, refined over more than 90 years of operational excellence. This structured approach not only streamlines the supply chain but also simplifies product tracking, servicing, and part replacement for distributors, retailers, and end-users alike.
Every TotalFlo water pump, including the TF117MS-18, carries a unique model number constructed using a consistent format that encapsulates key product specifications:
- Product Series Abbreviation – The code begins with “TF”, denoting the TotalFlo series.
- Flow Rate Indicator – The following number (e.g., 117) represents the pump’s maximum flow rate in litres per minute (L/min).
- Pump Type Code – Next is a letter or group of letters that identifies the pump type. In this case, “MS” indicates a multistage configuration, while “J” is used for jet pumps and “S” for sump pump variants.
- Cut-in Pressure Value – The final digits refer to the cut-in pressure, expressed as bar multiplied by 10. For example, “18” denotes a cut-in pressure of 1.8 bar (180 kPa).
Therefore, for model TF117MS-18:
- TF = TotalFlo series
- 117 = Delivers up to 117 litres per minute
- MS = Multistage pump design
- 18 = Cut-in pressure of 180 kPa (1.8 bar)
This fixed sequencing not only distinguishes each pump within the TotalFlo lineup but also ensures rapid identification when performing maintenance or ordering replacement parts. Davey Malaysia’s service technicians and retail partners rely on this nomenclature to retrieve the exact specifications or internal components required for each unit.
Beyond servicing, the identification system is also critical for inventory control and supply chain logistics. Each model’s unique SKU enables seamless tracking from the factory floor to retail shelves and customer installations. Internally, it also supports efficient inventory sorting and allocation across Davey’s regional warehouses, all of which maintain extensive in-house records tied to the serialised model numbers.
By adhering to this comprehensive product coding structure, Davey ensures that every pump, whether it’s a compact jet model or a high-performance multistage system like the TF117MS-18, can be quickly and accurately identified for any operational, maintenance, or logistical requirement.
Pressure tank as an attachment
While the TF117MS-18 is fully capable of operating on its own, pairing it with a pressure tank offers several practical advantages, especially for households with varying water usage patterns.
Reduces Pump Cycling: The pressure tank acts as a water reserve, storing pressurised water and reducing how often the pump needs to start and stop. This helps minimise wear and tear on the pump, extending its operational life while also preventing water hammer, a surge of pressure that can damage plumbing and pump components.
Maintains Consistent Water Pressure: By using a diaphragm or bladder inside the tank to maintain pressure, users experience smoother and more consistent water flow even during peak demand. This is particularly useful for multi-outlet homes or properties with multiple bathrooms.
Improves Energy Efficiency: With fewer pump activations, the system consumes less electricity. This not only saves energy bills but also reduces the carbon footprint over time, supporting a more environmentally friendly household operation.
Tank Capacity: Davey allows a pressure tank size of up to 8 litres (2.11 gallons) to be integrated with the TF117MS-18. The tank stores water and releases it as needed without activating the pump each time, ensuring smooth and efficient operation.

Volute construction
The volute in the TF117MS-18 is a critical component, engineered to guide water efficiently from the impellers to the outlet while protecting internal parts. Built using SUS304 stainless steel, the volute offers excellent corrosion resistance and strength. This is important for homes that draw water from different municipal sources, such as SYABAS or Penang Water Supply, which may contain mineral traces.
The internal spiral casing shape is optimised to allow water to swirl centrifugally. As water travels along the volute’s curved path, its velocity is converted into pressure with minimal turbulence. The volute casing also acts as a shield against external impact, sand, or debris that could compromise the pump’s internal mechanics. A clean, reflective finish offers both visual appeal and easy maintenance.
This construction ensures long-lasting use and consistent performance, even in environments exposed to moisture, grit, or physical wear.
Impellers and diffusers
The TF117MS-18 pump is equipped with a four-stage pumping system, each featuring stainless steel impellers and diffusers designed to multiply water pressure progressively, making it ideal for users seeking stable pressure with low maintenance.
Impellers: Enclosed (closed-type) stainless steel impellers are precision-machined for optimal centrifugal action. These create high water velocity with minimal energy loss, even during continuous operation.
Diffusers: Positioned after each impeller, diffusers efficiently convert water velocity into pressure. Their staged placement ensures that each cycle builds on the previous one, resulting in a strong, steady outlet pressure.
Performance: The multi-impeller design enables the pump to meet the demands of multi-storey homes, garden irrigation, or simultaneous water usage across multiple outlets.
Durability & Flow: Stainless steel construction resists wear from friction and water exposure, while the smooth surface finish reduces internal drag and supports a quiet, energy-efficient operation.
Gasket, backplate and mechanical seal uses
To protect the motor and internal workings of the TF117MS-18, high-quality sealing components are built in to prevent leaks and maintain structural integrity.
Mechanical Seal: Installed along the shaft near the motor housing, this seal keeps water from entering the motor chamber, ensuring safe electrical operation and reducing the risk of failure due to moisture intrusion.
Rubber Gasket: Positioned between major pump components such as the volute, backplate, and motor, the gasket maintains a tight seal and absorbs vibration, by reducing mechanical stress on the pump during operation. Minimises noise by limiting direct metal-to-metal contact, making the pump quieter.
Backplate: Acts as the final defence against backflow or splashes reaching the motor. It supports all mechanical parts and contributes to the pump’s structural stability.
The diagram below shows several key internal parts of the TF117MS-18 centrifugal pump, including the suction inlet, volute casing mechanical seals and gasket, designed for optimal household water pressure performance.
O-ring uses
The TotalFlo TF117MS-18 water pump is engineered with precision sealing components to maintain watertight integrity and mechanical durability. Among the most critical of these are the O-rings, which are strategically fitted at various connection points throughout the pump.
These O-rings are crafted from EPDM (ethylene propylene diene monomer), a high-performance synthetic rubber known for its excellent resistance to heat, wear, and chemical exposure. EPDM is preferred over other materials like neoprene due to its superior temperature tolerance, an important factor in scenarios involving prolonged pump operation or the handling of viscous, slurry-like liquids. Such conditions can generate significant internal heat, and EPDM maintains its elasticity and sealing strength even under those demanding circumstances.
By forming airtight and watertight seals, these O-rings help prevent internal leaks, reduce pressure loss, and maintain overall system efficiency. Regular inspection and timely replacement of worn O-rings are essential to preserving the pump’s long-term performance and reliability.
