Preventive Maintenance


It pays to have a preventive maintenance program with Pacific Electro-Mechanical, Inc. Our program has evolved over 40 years of designing, selling, fabricating, installing and servicing pumping systems. We have established a thorough system of checks and performance tests to minimize unforeseen outages while maximizing system performance.

Our preventive maintenance program provides customers with benefits including:

  • Extended equipment life

  • Lower operating costs

  • Greater peak performance

  • Smoother operation

  • Reduced system stress




Pacific Electro-Mechanical, Inc.’s comprehensive preventive maintenance program includes the following during each preventive maintenance visit:

  • Preliminary discussions with operators and observance of pump station operation

  • Inspect critical structure components for corrosion, wear and fatigue

  • Lubricate pump motors in accordance with motor manufacturer’s recommendations

  • Adjust packing glands and clean packing box drains

  • Check of each pump and motor for unusual vibration

  • Test each pump performance under varying flow conditions, if possible

  • Check system pressure, voltage and motor amperage at shut-off condition

  • Check all electrical connections for tightness, test all electrical components for proper operation and make adjustments, if necessary

  • Check condition and operation of all manual and check valves

  • Clean flow sensor and wye strainers in system controls

  • Test for operational correctness and make necessary adjustments to hydraulic control and relief valves, if applicable

  • Clean filters as required (certain filtration systems will require a dedicated trip which is in addition to the basic PM inspection)

  • Instruct on-site personnel in proper operation and maintenance of pumping equipment and controls
