The reliable operation of an irrigation pump station is a crucial element in turf grass management. While many golf courses have trained mechanics and comprehensive maintenance programs for mowers and other equipment, the irrigation pump station is often under-maintained. Pumping systems have become increasingly complex, and effective service requires specialized expertise from factory-trained technicians to assure optimum efficiency.

Routine preventative maintenance has several benefits:

o Extended equipment life
o Lower operating costs
o Minimize unscheduled emergency service calls
o Greater peak performance
o Smoother operation and reduced stress on the irrigation system
o Trending components to predict replacement

Our Checks Include:

o Voltage and current checks

o Pump performance analysis
o Electrical component inspections
o Control logic testing/calibration
o Motor winding insulation checks
o Control valve inspection & calibration
o Safety logic testing/calibration
o Mechanical component inspections

Preventative Maintenance Includes:

o Lubrication of motor bearings
o Changing oil in turbine motors
o Re-packing pumps
o Setting and Operation of electrical control components, including programmable logic controller and variable frequency drives.

Routine Control Valve Service Includes:

o Component disassembly for inspection and cleaning
o Replacement of stem O-rings
o Pilot valve calibration
o Repair kits are installed in pilots and main valve bodies at appropriate intervals to reduce the chance of control valve failure, which can create system over pressure and pipeline blowouts.

Calibrate, Update, and Review

The final step of the service procedure is to calibrate and test the station for overall smooth performance. Complete service data is kept on file and updated with every preventative maintenance service.


Test information is reviewed after every service to establish trends in equipment wear and deviation from original specifications. Major repairs can often be anticipated and overhauls scheduled for convenience rather than wasting time and money on emergency repairs during the peak watering season.

Preventative maintenance service visits are scheduled in advance with a confirmation call the day before the service. Cost of the service varies depending on system type, the number of pumps and optional equipment on the pump station.

 Neglected control valves may cause serious problems. To insure that your control valves and high pressure relief valves opererate properly the manufacturer reccommends rebuilding your valve every 3-5 years.

 With the bonnet removed we can expose the diaphragm and inspect the spring, stem, and upper disc. Usually these components are heavily corroded and covered in silt.

Further inspection often reveals that the control valve is harboring solid debris.

Removing the diaphragm exposes the body of the control valve, the lower disc, and guide disc,  allowing it to be inspected and cleaned. 

All of your valve's control pilots are rebuilt and outfitted with new diaphragms, o-rings and gaskets. The control valve is then reassembled and is ready to go back to work for you.
