Horizontal Multistage Booster Pump with An Anti-Vibrator Helps to Reduce Vibration & Noise

Horizontal multistage booster pumps are used to sequentially increase the pressure of liquids through the action of multiple impellers to achieve the delivery of high-pressure and high-flow liquids. The motor shaft is reinforced, and the pump has a compact structure and a small size, occupying minimal space. The liquid flows in from the axial inlet and out from the radial outlet. They operate stably and are suitable for conveying liquids that are cold, hot, clean, non-flammable, non-explosive, and free of solid particles or fibers. They are commonly used in air conditioning systems, cooling systems, flushing and cleaning systems, water treatment systems, aquaculture, and other applications.

The motor frequency of horizontal multistage booster pumps is available in both 50Hz and 60Hz. When the motor frequency increases, the motor speed also increases. With the same period of time, the 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 horizontal 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.
