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.
