The Non-reversing Bulk Pump Assembly contains three components that should be veri-
fied for proper operation every six months.
Routine maintenance will ensure optimum operation and performance of the Non-revers-
ing Bulk Pump Assembly. We recommend the following maintenance schedule and tasks.
Weekly or as often as necessary
•
r Check and clean the pump inlet filter.
An inlet filter has been provided to protect the pump from solid material that
can enter and damage the pump impellers. Material can enter the vacuum line if
a loader filter is improperly installed or if it has a hole in it. Replace the pump
inlet filter if it is torn or worn.
r Check all V/belts.
The V/belts have a tendency to stretch, so an adjustable motor base is provided.
Keep belts tight to prevent slippage and wear. Do not use belt dressings.
• Every 500 hours of operation
r Grease the pump.
Use No. 2 bearing grease or the equivalent. Refer to manuals from the compo-
nent manufacturer for additional information and instructions.
Every 1500 hours of operation
•
r Change the oil.
The vacuum pump has been filled with the proper oil and tested by Conair
before shipment. Even so, this oil should be changed periodically. Use SAE 40
regular or an equivalent oil.
• Every three months
r Check motor bearings and grease, if necessary.
The motor is equipped with double-shielded ball bearings having sufficient
grease to last indefinitely under normal service. But if the motor is used con-
stantly in dirty, wet, or corrosive atmospheres, you should add 1/4 oz. of grease
per bearing every three months. Use a quality, rust-inhibiting, polyure-based
grease such as Chevron SRI. Refer to the motor manual for additional instruc-
tions.
• Every six months
r Check the vacuum relief valve for proper operation.
The vacuum relief valve is designed to protect the pump from damage if the
conveying line becomes clogged or obstructed.
