Service & Repair

Common Centrifugal Pump problems stem from mechanical seal failures, resulting in leaks. Other issues include wear plate damage, clogged impellers, signs of ingress, and more.

• Mechanical seal failure
• Leakages
• Scoring to front wear plate & neck ring
• Clogged impeller
• Clogged suction line
• Missing nuts/bolts on the impeller
• Signs of ingress

Diaphragm Pumps commonly face issues such as breached diaphragms, valve blockages, and worn components, leading to leakages and inefficiencies. Regular maintenance and worn-part replacement are vital.

• Air pressure too low
• Blocked suction/discharge
• Damage to diaphragms & valve balls
• Improper sealing caused by loose diaphragms
• Leaks caused by loose side housing
• Distortion of diaphragms and ball valves
• Entrapment of solids in the pump chamber

Lobe Pumps encounter issues such as leaking mechanical seals, snapped bolts on shafts, and wear to the casing and lobes. Wear from age and use requires seal and component replacements for continued operation.

• Leaking mechanical seals
• Snapped bolts in shaft
• Wear to casing and lobes
• Scoring/grinding on pump components
• Casing and lobe clearance tolerances out of specification
• Wear on shafts
• Inefficient measures to prevent ingress

Peristaltic Pumps commonly experience reduced performance and flow rates caused by issues such as hose deformation, loose components, and wear in the hub assembly. Proper maintenance and replacement of key components is essential.

• Hose rupture
• Misshaped hose
• Loss of elasticity in hose
• Loose hub screws causing wheel stalling
• Wear and shaving of hub taper lock
• Metal debris from hub shaving in shaft keyway
• Wear on seals, seal sleeves and O-rings
