BHP 80 High Pressure Pump

How to extend the service life of the pump, maintain its pumping stability, and avoid particle wear on the pump?

In order to prolong the service life of the pump and maintain its pumping stability, please make sure that the working conditions of the medium are consistent with the required working conditions. In order to avoid particle wear to the pump, we strongly recommend that you install an appropriate filter in front of the pump (the main filter must have a filtration efficiency of 99.98% for particles above 10μm).

How to avoid cavitation and dry rotation?

To avoid cavitation and dry running, it is recommended that you install a low-pressure protection switch before the pump inlet. Please refer to the parameter table in the technical specifications of the high-pressure pump for the minimum inlet pressure of different types of pumps. Please go to BHP 50~100.

What are the requirements for the frequency converter?

Frequency converter requirements: If the pump needs to be equipped with a frequency converter, the frequency converter must be a heavy-duty constant torque, and the starting mode is constant torque starting. (Please pay attention to the selection of the frequency converter. The frequency converter for water pump fan is not constant torque, and may not be able to drive the positive displacement water pump. For example, the AC510 of ABB frequency converter cannot drive the BHP high pressure pump. The same is true for other brands of frequency converters. Please pay attention to the inverter manufacturer communicates and selects).

What do we need to pay attention to in the use of high-pressure pumps?

Please pay attention to the continuous inlet pressure, maximum peak inlet pressure, maximum continuous outlet pressure, and minimum outlet pressure operating ranges of different types of pumps; please ensure that the pressure during operation of the pump does not exceed the range required by the specification.

What to pay attention to when installing this series of high-pressure pumps?

"I" represents the inlet of the high-pressure pump, and "O" represents the outlet of the high-pressure pump.

During installation, the coupling installation clearance between the high-pressure pump and the motor must be at least 3-5mm.

The figure below shows how to connect the motor to the high-pressure pump

What should be paid attention to when starting and debugging the high-pressure pump?

Before starting the pump, it is recommended that you thoroughly flush the pipeline and system to remove any residues or foreign objects that may exist;

Before starting the pump, it is strongly recommended that you exhaust the air in the pump and the system;

Test whether the direction of the high-pressure pump is consistent with the arrow mark on the pump.

Which operating environment BHP series axial piston pump is not suitable?

The BHP series axial piston pump must not be used in sewage or other water containing particles.

Under what circumstances does this series of pumps need to be stopped or overhauled?

If abnormal noise and vibration occur when the pump is running, please stop the piston pump immediately and perform maintenance on the piston pump.

How to use the high-pressure pump correctly?

It is forbidden to start the piston pump with the back-end valve closed, otherwise it may cause the safety valve to work, or even the pipeline burst.

Which connection method is used to connect the high-pressure hose?

It is recommended that the outlet of the BHP series axial piston pump adopt a flexible connection method of high-pressure hose.
