|Process Pumps (Diaphragm Pumps)

What is the flow adjustment method for PA and PB series process pumps?

The process pumps themselves do not have a flow adjustment function.
Follow the procedure below to adjust the flow rate.
For the automatically operated type
Install a needle valve or other flow adjustment valve on the outlet side of the process pump to adjust the flow rate.

For the air operated/built-in solenoid valve type:
Install a needle valve or other flow adjustment valve on the outlet side of the process pump to adjust the flow rate.
The flow rate can then be adjusted by changing the switching frequency of the solenoid valve for driving the pump.
