Booster Pumps under 3.7kW are water pumps with a capacity of less than 3.7kW, operating on 1-phase or 3-phase electricity. Booster pumps operate automatically and save energy, helping to increase water pressure in residential and small industrial systems. This is an effective solution to improve water pressure, especially in areas with uneven water demand or insufficient pressure. Water pumps under 3.7kW are favored for their energy-saving capabilities and suitability for small and medium-sized projects.

Applications of Booster Pumps under 3.7kW
Booster Pumps under 3.7kW feature a small to medium power range, suitable for residential systems and some small-scale technical applications. The equipment helps improve water pressure, maintain stable flow, and save energy during operation.
Boosting water pressure for daily life and offices: Used to boost pressure for houses, apartments, small offices, or business stores. The pump helps water flow stronger and more evenly at usage points such as showers, lavabos, and washing machines, ensuring a convenient living experience.
Supporting solar water heater systems: Installed in solar water heater systems or indirect water heaters to boost output pressure. The device helps stabilize the hot water flow, especially in areas with weak supply pressure.
Applications in light industry: Can be used for local cooling mist systems, supplementing pressure for internal pipelines, or supplying water for some small production equipment. The machine operates stably, suitable for continuous use without requiring large flow rates.

Booster Pump Prices under 3.7kW at Thanh Thai Motor
At Thanh Thai Motor, we provide high-quality booster pumps that meet the needs of residential and small industrial projects. Below is the latest price list for Booster Pumps under 3.7kW in 10/2026 for your reference and to choose the right water pump.
Why does the booster pump under 3.7kW make a continuous “click-click” noise even when no one is turning on the faucet to use water?
This phenomenon occurs due to water leaks in the piping system or equipment (showers, toilet floats, washing machines), or because the pump’s pressure tank is damaged (punctured rubber bladder/leaked air). When pressure compensation space is lost, just a small amount of water escaping causes the pressure to drop deeply, causing the relay to close, and then the pressure immediately spikes, causing the relay to open, forming a continuous switching loop.
How to adjust the pressure screw on the booster pump relay when the machine refuses to shut off or shuts off too late?
On the mechanical relay, there is always a spring force adjustment screw (usually marked with + and – signs). If the pump runs continuously without shutting off, use a screwdriver to turn it counterclockwise (toward the – sign) to reduce the relay’s shut-off pressure to suit the actual pushing force of the machine. Note that you should only turn it a little bit (about 1/4 turn) and open/close the faucet to test again until the pump switches smoothly.
What is the core difference between installing an inverter booster pump compared to a conventional mechanical booster pump in this power range?
Mechanical booster pumps only run at a fixed speed (100% capacity), leading to excessive pressure causing a harsh sound when turning on 1 faucet, while turning on multiple faucets makes it weak. Conversely, inverter booster pumps under 3.7kW will automatically increase/decrease the motor’s rotational speed based on the number of open faucets, keeping the water pressure at every location consistently stable, saving electricity and protecting pipelines from pressure overload.
