Conair positive displacement vacuum pumps are designed for
long distance, high-volume material conveying applications.
DESCRIPTION
Each model employs a powerful, rotating lobe-type blower,
protected by a vacuum relief valve (factory-set to 12 in. Hg)
and belt driven by a three-phase motor with magnetic starter
and overload protection. An integrated pump protection filter
is included and all components are mounted on a rugged
frame, housing an integrated exhaust muffler.
An optional sound enclosure may be added to reduce noise
when installed near plant personnel.
Positive Displacement Pumps provide the strongest vacuum
power available, but when operated for long periods at high
performance levels, noise should be abated if the pump is
located near personnel. Sound Enclosures are available for all
pump models and provide maximum noise control with mini-
mal space and easy access to pump maintenance areas.
OPTIONAL
SOUND
ENCLOSURES
Super Quiet Sound Enclosures include externally mounted
protection filter, vacuum gauge and filter gauge; 8 ft exhaust
stack (for noise); and easy access, tool-free front door.

Set or mount the vacuum pump in any convenient location.
INSTALLING
THE PUMP
Refer to the accompanying wiring diagram for connection of
the main power supply and the conveying control circuit.You
must provide a wall-mounted disconnect for three-phase elec-
trical connection. Incoming voltage and current must match
the electrical specifications on the pump data plate and serial
tag. Check for proper rotation of the pump after power has
been connected and before operation.
Install vacuum lines to loader stations and the dust collector.
Connect the dust collector vacuum outlet to the pump inlet.

INSTALLATION AND OPERATION NOTE:
The pump inlet is equipped with a vacuum relief
valve to prevent the vacuum from exceeding 12 in.
Hg. Excessive vacuum will reduce the life of the
pump and can destroy it.
For special applications requiring a higher vacuum
level, consult Conair service. If the vacuum relief
valve is adjusted by any person other than a facto-
ry service representative, the warranty is voided.

To maintain the best performance, you should follow the
maintenance recommendations outlined here and in any
included manuals from component manufacturers.
PREVENTATIVE
MAINTENANCE
SCHEDULE
● Weekly, or as often as needed
❒ 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 if has a hole in it.
Replace the pump inlet filter if it is torn or worn.
❒ Check all V/belts.
The V/belts have a tendency to stretch, so an adjustable
motor base is provided. Keep belts tight to prevent slip-
page and wear. Do not use belt dressings.
● Every 500 hours of operation
❒ Grease the pump.
Use No. 2 bearing grease or the equivalent. Refer to
manuals from the component manufacturer for
additional information and instructions.
● Every 1500 hours of operation
❒ 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
❒ 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
constantly 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 instructions.
