The installed electric diaphragm pump experiences excessive vibration; does anyone have any solutions? Note: The outlet pressure of this pump is required to be less than 0.3 Mpa.

First, it is necessary to figure out where the vibration is coming from Is it the motor or resonance? Based on the photos, if resonance is occurring, it is recommended to adjust the installation angle of the valve, or use other methods to disrupt the resonance frequency and eliminate it. If the motor vibrates heavily, then service the motor.

The pulse of the diaphragm pump is quite large. It’s my first time seeing a vertical electric diaphragm pump; the outlet side has been modified in this way

What were the original parameters of the pump, namely flow rate and head?
