Common failures & inspection points

Inlet pressure exceeds maximum rated specification (MQ max 45 psi, CMBE max pressure rated)

Verify inlet pressure gauge reading does not exceed pump datasheet maximum inlet pressure specification

Pump cavitation due to inadequate inlet conditions or excessive suction lift

Check suction line for air leaks, ensure suction lift does not exceed 1 meter, verify intake filter is not clogged

Diaphragm tank pressure setting incorrect or tank bladder failure (CMB, MQ, SBA models)

Measure tank pressure with gauge when pump is off; pre-charge pressure typically 0.8-0.9x minimum operating pressure

Discharge pressure exceeds 10 bar (145 psi) design maximum causing component stress and leakage

Monitor outlet pressure gauge continuously; pressure relief valve should activate at maximum rated pressure

Water temperature exceeds +55°C causing seal damage and reduced pump life

Install thermometer on discharge line; verify liquid temperature stays within -20°C to +55°C operating range
