|Process Pumps (Diaphragm Pumps)

What are the possible causes of a PB series process pump with a built-in solenoid valve (PB1011A) not operating even when compressed air is supplied and the product is energized?

PB series process pumps with a built-in solenoid valve (PB1011A) are equipped with a solenoid valve inside. Simply energizing this solenoid valve does not drive the pump.
When the solenoid valve is turned ON/OFF, the diaphragm operates, and the fluid is sucked in and discharged alternately.
