What is the HPD Pump?
Conair HPD Pumps are designed for long distance, high-volume material convey-
ing 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 protection. An integrated pump protection filter is
included and all components are mounted on a rugged frame, housing an integrat-
ed exhaust muffler.

Typical Accessories and Options
Vacuum pumps traditionally work directly with dust collectors, cyclones or other filters that are
designed to remove plastic dust from the incoming air line to prevent contaminants from circulating
through the vacuum pump. In some cases, operation of the pump without a dust collection system
can create pump damage or a hazardous condition resulting from flammable or low melt-point plas-
tic material being exposed to the elevated operating temperatures of the pump.
Each HPD model includes a combination vacuum relief/idle mode valve. The valve allows the vacu-
um pump to remain operating for a period of time after the run signal from the loading control is
interrupted. This can greatly lengthen pump life by eliminating rapid start/stop cycles common to
many vacuum loading systems. Instead of shutting down, the pump continues to run for a minimum
of five minutes while vacuum pressure is relieved through a compressed air-operated valve that
bleeds ambient air into the vacuum inlet line of the pump. A clean compressed air source must be
provided to the valve solenoid for it to operate.
An optional air cooler option may be easily integrated into the assembly to reduce the temperature of
conveying air entering the pump for conveying applications that move heated materials.

3-2 l Installation
Unpacking the Boxes
HPD Pumps are typically shipped bolted to a pallet and either enclosed by a box or
simply wrapped in protective plastic sheeting.
1Carefully remove the box or wrap and unbolt the unit from the shipping
pallet. When unpacking, make sure that all packing material is completely
removed from the pump, paying special attention to the inlet and outlet tubes
and crevice areas, to prevent potential damage caused by the packing materials
during the heat and suction of the pump’s operation.
2Once the pump is unbolted from the pallet, carefully move the pump using
a fork truck, crane or other lifting device. Use caution as the pump is trans-
ferred off the pallet and into the desired location for installation.
Preparing for Installation
The pump should be located in a protected, indoor location. Three phase power
will be required and a fused disconnect switch (not included) is required near the
pump. For use of the idle mode valve, compressed air will also be required near
the pump. Tubing connections to the pump are typically made with a flex hose to
allow easy connections.
Securing the pump to the floor with bolts is not strictly required, but is recom-
mended to prevent the minimal motion that could occur as the pump ages or in the
event of malfunction caused by contamination of the air stream.
The pump will only require minimal maintenance, but should still be located
where it is accessible and where its vacuum gauge is easily read by set-up and
operation personnel.
WARNING: You are
responsible for the
structural integrity of
this installation.

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 or installation above
1500 ft elevation, consult
Conair service.

Installing the pump
1Use a fork truck to carefully move the pump into its operating location.
2Use care in orienting the pump for easy access to its pump starter and clearance
for the opening of its lid and allowing easy visibility of its vacuum gauge.
3Note the inlet and outlet of the pump. Generally, the outlet will simply exhaust
conveying air out of the muffler, but it may also be plumbed outside if desired, as
long as the exhaust line expands the size of the tube as it follows its path to
exhaust. The inlet stub will be connected to the dust collector or cyclone of the
system.
4The use of flex hose for pump connections is recommended, to allow easy
movement or service, if needed. Line up and coordinate all connections to allow
for easy connections, but wait until pump rotation has been established (and cor-
rected, if need be) before completing installation.
5Connect the dust collector or cyclone vacuum outlet to the pump inlet.
6Tighten all coupling bolts evenly. Tubing must not put a strain on the inlet or
outlet of the pump connections or eventual leaks will occur.
7Maintain an air space all around the pump for ventilation. Do not block or
cover any portion of the cooling fins that would prevent free air movement or
reduce cooling effectiveness.
8Connect 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.

Installation

3-4 l Installation
Checking Rotation
Upon initial start-up, but before normal operation, the HPD Pump must be checked
for proper rotation.
1 Set the loading controls to a minimal operating cycle (very low load time
setting of a single receiver, see separate loading control manual) and check the
pump with no vacuum or exhaust tubing or flex hose installed.
2Double-check air flow to confirm actual flow direction. If air is exiting from
the filter inlet, see step 3. If direction is OK, proceed.
3If direction is backwards, disconnect power and change any two of the three
phase leads coming into the pump starter. Upon confirming proper rotation,
reconnect power and complete the tubing installation for operation.
The HPD Pumps operate in response to signals provided from a loading control,
located elsewhere, and wired to the pump starter or the Transformer/Idle Mode
Control. Once properly installed, the pump should respond to signals from the
loading system and run according to the Idle Mode timer (if used) and the loading
control. Operation (on-time, etc) is determined solely by the loading and Idle
Mode Control Systems. The only change to operation that can occur within the
pump assembly itself is a motor overload within the pump starter or a malfunction.
If this occurs, see Troubleshooting section.
WARNING: This equipment should be installed, adjusted, and serviced by qualified
technical 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.
CAUTION: Never place your
hand directly over the inlet or
the exhaust.

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
❒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 receiver filter is improp-
erly 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 manufac-
turer 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 synthectic viscosity 220 or 320 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 corro-
sive atmospheres, you should add 1/4 oz. of grease per bearing every three months. Use a
quality, rust-inhibiting, polyure-based grease such as a NLGI #2 premium grade microgel
grease with 250°F {121°C}service temperature and moisture resistance and good mechani-
cal stability. Shell Darina EP NLGI Grade 2 is an example of this. Refer to the motor man-
ual for additional instructions.
●Every six months
❒ Check the idle mode/relief valve for proper operation.
The idle mode/relief valve is designed to protect the pump from damage if the conveying
line becomes clogged or obstructed.
4-2 l Maintenance

Inspect the idle mode/relief valve
The idle mode/relief valve is designed to protect
the pump from damage if the conveying line
becomes clogged or obstructed. To check the
valve:
1Partially 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
or adjust the valve.
Note: Gauges should be
checked/calibrated every
12 months.
✐
Maintenance l 4-3
CAUTION: Hot sur-
faces. Always protect
yourself from hot sur-
faces inside and outside
the pump.
Cleaning the Pump Inlet Filter
WARNING: High voltage. Always stop the pump, disconnect and lock out the
main power source before troubleshooting or performing repairs.
Clogged filters reduce air flow and pump efficiency. Cleaning frequency
depends on how much material you process
and how dusty or full of fines it is.
1Remove the hand knob and pull the filter
lid off.
2Remove the filter hand knob, then
remove the filter.
3Clean the filter by laying it on its side and
gently tapping it on the floor. Replace
damaged, worn, or clogged filters.
4Remove any dust which may have accu-
mulated in the pump inlet filter housing.
5Reverse the procedure to reinstall the
dust collector filter. Ensure that the lid gas-
ket is in place and in good condition.
CAUTION: Wear eye
protection. If you use
compressed air to clean
equipment, you must
wear eye protection and
observe all OSHA and
other safety regulations
pertaining to the use of
compressed air.
CAUTION: Hot sur-
faces. Always protect
yourself from hot sur-
faces inside and outside
the pump.

Maintenance

4-4 l Maintenance
Cleaning the Idle Mode/Relief valve
1Stop the vacuum pump, disconnect and lockout the main power to the pump.
WARNING: High voltage. Always stop the pump, disconnect and lock out the main power
source before troubleshooting or performing repairs.
2Thoroughly inspect the idle
mode/relief valve. Check inside
and out for any signs of contamina-
tion, residue or other foreign sub-
stances that may potentially block
the motion of the internal, spring
loaded valve plate.
3Clean the inner components of
the valve. Use a cleaning agent
that will dissolve any plasticizer or
oily build-up on the surfaces of the
idle mode/relief valve. Be sure to
clean between the valve plate and the valve seal. 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 idle mode/relief valve.)
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.
