A set of vertical multistage booster pump

Vertical Multistage Booster Pump for Applications Requiring High Pressure Delivery

Vertical multistage booster pump is a multifunctional stainless steel lightweight pump driven by a standard electric motor. It can convey a wide range of different media from tap water to industrial liquids, and is applicable to different temperature ranges, flow ranges, and pressure ranges. It has two or more impellers on the pump shaft to meet the needs of high-pressure delivery. The pump is equipped with an intelligent protector to effectively prevent dry running, phase loss, and overload.

The motor frequency of vertical multistage booster pumps is available in both 50 Hz and 60 Hz. When the motor frequency increases, the motor speed will also increase. With the same period of time, the booster pump operating at a frequency of 60 Hz below will handle more fluid, so the flow rate will also increase. Our customers can choose the motor frequency according to their specific needs.

General Data
  • Liquid temperature: room temperature type: -15 °C to 70 °C; hot water type: +70 °C to 120 °C
  • Viscosity: If the density or kinematic viscosity of the output liquid is greater than that of water, the pump pressure and hydraulic performance significantly change, power consumption rises, in this case, the pump must be equipped with a larger power motor.
  • Operating environment: The maximum ambient temperature of the pump is +40 °C. If the pumps are used at a temperature above +40 °C, or their motors are installed at an altitude higher than 1,000 m, the output power of the motors is reduced, as shown below. In this case, motors with a higher output power are needed.

For example, according to the figure above, the motor power P2 will drop to 84% when the pump is installed at an altitude higher than 3500 m, or to76% when the ambient temperature is 70 °C.

Working Principle

The vertical multistage booster pump is connected to the water source through an inlet pipe.

Each impeller connected to the motor shaft has its own blades, and the number of blades gradually increases. This design makes the water subject to higher pressure as it passes through each impeller. The water enters the pump through the inlet, and as the impellers rotate with the motor, the centrifugal force generated by the rotating impellers pushes the water towards the edges of the impeller. The pressure gradually increases, and each impeller adds pressure to the water, allowing the water to flow at a higher pressure. The high-pressure water is discharged through the outlet pipe connected to the pump. It can be directed to the desired location or connected to other systems for further distribution and use.
