Daily Maintenance Checklist
□
Inspect the pump to ensure that all the exposed threads are coated with rust inhibitor.
□
Check the oil in the power end, lubricator and chain case. If the oil is contaminated,
replace. If not, ensure that the oil temperature is within range and add oil as needed.
Always allow the pump to stand idle for approximately five minutes before checking oil
level.
□
Check the extension rod packing for proper alignment and lubrication. Adjust as needed.
□
Ensure that the liner wash and charging pumps are properly lubricated.
□
Lubricate the shaft and packing of the liner wash pump as instructed by manufacturer.
□
Check the pressure gauges on the external lube oil filter (if utilized). If the differential
between the gauges is greater than 15 psi when the pump is at operating temperature,
clean the strainer and strainer magnets.
□
During operation, examine the belt drive (if utilized). If slipping or squealing is noticed,
disengage and turn off belt drive and adjust tension as necessary. Be sure to check the
sheave alignment before returning to service.
□
Observe the condition of the pistons and liners, and look for uneven wear or corrosion, or
excessive bypass on each stroke (smooth wear and minor leakage is to be expected). If
this occurs, replace pistons and/or liners as necessary.
□
Check the pressure in the suction system, ensuring it is within range.
□
Check the pressure in the discharge system, ensuring it is within range.
□
Check that the pulsation dampener & suction stabilizer are set to the correct pressure.
□
Check the entire pump for oil or fluid leaks, including the diaphragm and the oil seals in
the power end.
□
Check to ensure the pump is clean and ready for work.
□
Check to ensure the work area around the pump is clean and free from hazards.
□
Drain any piston leakage from the pump.
