5 MAINTENANCE
Simplex Pump Sets should be visually inspected for maintenance
purposes every six months during light duty cycles. Pumps sets used
daily for long hours should be inspected every month.
• Prior to performing the maintenance procedure ensure that the
optional main disconnect switch illustrated above is operating
properly, the user supplied circuit breaker is in the
OFF
position,
and that all sources of power are isolated from the Pump Set.
Proceed only after this is verified.
• Check main disconnect switch, door and hinge operation.
• Check cabinet mounting hardware at feet and wall mounting
flange. Tighten as necessary.
• Test pumps in duplex pump sets. Ensure both pumps are
operating normally, test each pump individually, test simultaneous
operation, test alternating operation.
• Check pump/motor hardware for tightness. Pump/motor
hardware for tightness. Pump/motor hardware will loosen after
normal operation due to vibration. This hardware is double nutted,
check all bolts for double nuts.
• Rotate shaft by hand and check for smooth operation. Check
pump/motor coupler shown at left for proper alignment and
spacing. The Lovejoy coupler should have approximately 1/8"
clearance between coupler halves. If this clearance is reduced or the
pump and motor are not properly aligned excessive noise and
pump/motor wear will occur. Loosen pump motor mounting
hardware to realign motor/coupler. Loosen one end of pump
coupler to adjust for necessary coupler clearance.
• Check all electrical terminals and connections for
tightness.
• All motors are permanently lubricated and do not
require any lubrication
• All pumps are self-lubricating and do not require
any maintenance.
• Check all plumbing joints for leaks. Tighten fittings
and joints as necessary. Drain accumulated fuel in
catch basin as necessary by removing catch basin plug.
• Inspect all fuel strainers. Disassemble strainer and clean strainer
element, replace as necessary. Re-assemble unit and check for leaks.
• Test hand pump operation, check for fuel leaks, tighten as
necessary
