Common Pump Issues

Experiencing pump problems? Our expert technicians diagnose and repair all types of pump failures quickly and efficiently.

Pump Leaking

Mechanical seal failures, worn packing, cracked housings, and gasket leaks. We identify the source and repair or replace components to stop leaks permanently.

Excessive Vibration

Unbalanced impellers, misalignment, worn bearings, or cavitation. Our diagnostics identify the root cause for targeted, effective repairs.

Loss of Pressure/Flow

Worn impellers, clogged passages, air leaks, or wear ring erosion reducing pump output. We restore pumps to original performance specifications.

Motor Won't Start

Electrical failures, seized bearings, or control issues preventing pump operation. We diagnose motor and control problems quickly.

Unusual Noises

Grinding, squealing, or cavitation sounds indicating bearing failure, impeller damage, or air entrainment issues requiring immediate attention.

Motor Overheating

Insulation breakdown, ventilation issues, overloading, or electrical problems causing motors to run hot and trip on thermal protection.

Cycling On/Off

Control system issues, pressure switch problems, or check valve failures causing pumps to cycle excessively and wear prematurely.

High Energy Bills

Inefficient operation from wear, misalignment, or improper sizing wasting energy. We optimize pumps for peak efficiency and lower operating costs.
