1l Introduction

Description
Conair Positive Displacement Vacuum Pumps are designed for long distance, high-volume material
conveying applications.
Each model has 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 protec-
tion. 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.
Optional sound enclosures
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 person-
nel. Sound Enclosures are available for all pump models and provide maximum noise control with
minimal space and allows easy access to pump maintenance areas.
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.

Installing the pump
1Set or mount the vacuum pump in any convenient location.
2Connect power. Refer to the accompanying wiring diagram for connection of the main power
supply and the conveying control circuit. IMPORTANT: You must provide a wall-mounted
disconnect for three-phase electrical connection. Incoming voltage and current must match
the electrical specifications on the pump data plate and serial tag.
WARNING: This equipment should be installed, adjusted, and serviced by qualified tech-
nical personnel who are familiar with the construction, operation and potential hazards of
this type of machine. All wiring, disconnects and fuses should be installed by qualified
electrical technicians in accordance with electrical codes in your region. Always maintain
a safe ground. Do not operate the equipment at power levels other than what is specified
on the the machine serial tag and data plate.
3Check for proper rotation of the pump after power has been connected and before
operation.
4Install vacuum lines to loader stations and the dust collector.
5Connect the dust collector vacuum outlet to the pump inlet.

Preventative Maintenance Schedule
To maintain the best performance, you should follow the maintenance recommendations outlined here
and in any included manuals from component manufacturers.
●Weekly, or as often as needed
❒ Visually inspect the oil level.
A sign glass window on the pump makes visual inspection simple. Regularly check to make
sure that the pump has the appropriate oil level.
❒ 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
slippage 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 (if using SAE oil)
❒ Change the SAE oil. Conair recommends the use of Synthetic oil.
The vacuum pump has been filled with the proper oil and tested by Conair before shipment.
This oil should be changed periodically. Use SAE 40 regular or a synthetic oil.
●Every 6000 hours of operation (if using Synthetic oil)
❒ Change the Synthetic oil. Conair recommends the use of Synthetic oil, which extends the
oil change regularity.
Extended oil change periods are accomplished by using the Conair recommended synthetic oils.
●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.
●Every six months
❒ 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.
5l Maintenance
Note: The PD Pump ships
from the factory with SAE
oil. Conair recommends
switching to a synthetic oil
after the first oil change.
✐

Inspect the vacuum relief valve
The vacuum relief valve is designed to protect the pump from damage if the conveying line
becomes clogged or obstructed. To check the valve:
1Remove the inlet hose on the inlet filter housing.
2Partially obstruct the inlet by using a rigid flat plate and slide it across the opening until 12
inches Hg registers on the gauge. Do NOT completely block the inlet. The relief valve should
open at approximately 12 inches Hg. Do not exceed 15 inches Hg. If the valve does not
release at or below 15 inches Hg, replace the valve.
3Reconnect the hose to the inlet of the pump.
Clean the vacuum relief valve
1Stop the vacuum pump, disconnect and lockout the main power to the pump.
WARNING: High voltage. Always stop the Positive Displacement Pump,
disconnect and lock out the main power source before troubleshooting
or performing repairs.
2Thoroughly inspect the vacuum relief valve. Check inside and out for any signs of contami-
nation, residue or other foreign substances that may potentially block the motion of the internal,
spring loaded diaphragm.
3Clean the inner components of the valve. Use a cleaning agent that will dissolve any plasti-
cizer or oily build-up on the surfaces of the vacuum relief valve. Be sure to clean between the
vacuum relief diaphragm and its seat. Spray the cleaning agent into the valve opening and then
flush out. The valve may require disassembly to reach critical areas.
IMPORTANT: If a valve can not be cleaned adequately it should be replaced to prevent malfunction or a
potentially hazardous condition due to inadequate vacuum relief.
4Reassemble the valve and re-adjust to the proper vacuum setting (see instructions for
adjusting the vacuum relief valve on the next page. )
Note: Gauges should be checked/calibrated every 12 months (if applicable).
✐
CAUTION: Wear eye protection. If you use compressed air to clean the equipment, you
must wear eye protection and observe all OSHA and other safety regulations pertaining
to the use of compressed air.
Maintenance l 6

Readjusting the vacuum relief valve
1Prior to checking the vacuum relief valve operation, confirm the operation of the vacuum
gauge on the pump. With the pump off, the gauge should read "0" inches of mercury (Hg).
The gauge should rise to a range between 5 and 15 inches of Hg as the pump runs. If it does not
operate accordingly, replace the gauge. Vacuum gauges are not repairable.
2Disconnect the flex hose from the inlet of pump protection filter.
3Access the vacuum adjustment screw. Remove the threaded cap from the vacuum relief valve
to allow to access the vacuum adjustment screw.
4Start the vacuum pump.
5Open the relief valve. Position a rigid flat plate partially over the pump's air inlet with the pump
running until the relief valve opens as indicated by an inrush of air into the valve. Note the read-
ing on the vacuum gauge. The exact point at which the valve opens to allow air to be sucked
into the pump should be 12 inches Hg.
6Establish the proper vacuum relief point. With a screw driver, turn the adjustment screw to
establish the proper vacuum relief point while restricting the opening at the vacuum inlet of the
pump. Repeat the procedure until you feel air entering the relief valve and vacuum reading is 12-
inch Hg on the vacuum gauge - max vacuum limit is 15 inch Hg.
7Replace the adjustment screw cap and reconnect the flex hose to the inlet of pump.
