INTENDED USE
Masport Vacuum / Pressure Pumps are intended to be used for loading and unloading of
liquid material. These pumps are commonly used for liquid waste transport, septic tank
cleaning, oil field service work, car wash or grease trap cleaning and many other
industrial applications. WARNING!
Masport pumps must not be used to move flammable or highly
caustic material. Use of this pump for moving hazardous material
may result in machinery failure, bodily injury or even death.
SETUP
The 4-way valve on the pump is used to change the pump operation from vacuum to
pressure or pressure to vacuum by rotating the handle 90 degrees. Either side of the
valve can be plumbed as the intake or exhaust port. Depending on how it is plumbed,
the vacuum or pressure indicators on the top of the valve may be reversed.
When designing the system in which this Masport pump will be installed it is important to
make sure all of the components and plumbing are of adequate size.
NOTE!
Using components or plumbing with a smaller I.D. than
recommended for a particular pump will result in poor system
performance and may damage the pump.
The HXL75 model pumps are designed with 2 1/2" NPT ports. Any components, hose or
fittings with a smaller I.D. will restrict air flow and may damage the pump.
The HXL15 and HXL400 model pumps are designed with 3" NPT ports. Any
components, hose or fittings with a smaller I.D. will restrict air flow and may damage the
pump.
NOTE!
Before assembling the system, make sure the inside surfaces of all
pipes, hose and fittings are clean and free of any kind of dirt or
debris. Any solid particles ingested by the pump may result in
higher operating noise, loss of performance or irreparable pump
damage.
Some form of pipe sealant should be used on all thread connections to prevent leaks.
HOSE
Any hose used in your system should be rated for at least 28" hg vacuum and 25 PSIG
pressure. It will also need to withstand an oil/air mixture at temperatures up to 300° F.
"Hot Tar and Asphalt" hose is designed for use in this type of environment.

RECOMMENDED SYSTEM COMPONENTS
PRIMARY SHUT-OFF:Prevents liquid in the tank from overflowing into the system
and entering the pump. Liquid entering the pump can damage or destroy the pump.
SECONDARY MOISTURE TRAP (SCRUBBER): Removes liquid still in the air
stream after passing through the primary shut-off. The Scrubber should be drained after
every load.
VACUUM/PRESSURE GAUGE: Required to properly monitor the performance of
the system. It should be located between the Scrubber and the Pump (the clean side of
the pump) to prevent gauge failure due to foreign material.
VACUUM RELIEF VALVE: Governs the operating vacuum level. It should be
installed at the pump so that if a liquid level trap is activated or a hose collapses the
pump is not allowed to deadhead which can result in overheating and pump failure.
PRESSURE RELIEF VALVE: Regulates the amount of pressure in the system. It
should be located between the Scrubber and the Pump (the clean side of the pump).
CAUTION!
Operating your system without a properly installed pressure relief
valve in good working order could lead to equipment damage or
catastrophic failure resulting in severe injury.
INLET FILTER: Prevents small particulate matter from entering the pump. This filter
should be checked and cleaned or replaced regularly.

5
OIL SEPARATOR (OIL CATCH MUFFLER):Removes oil from the pump exhaust.
It is equipped with a ball valve at the bottom and should be drained at least once a day.
OPTIONAL ODOR CONTROL (MASPORT PUMPER SCENT):Reduces
objectionable odor from the exhaust air.
PUMP DRIVE
The pump can be driven from either of the two shafts to accommodate a clockwise or a
counterclockwise drive system. There is an arrow cast into the pump housing and/or the
valve housing indicating proper pump rotation. The pump must always rotate in the
direction of the arrow.
NOTE!
The pump should never be run backwards. Operating the pump in
the opposite direction will cause damage.
RECOMMENDED PUMP SPEED
The recommended pump speed for best operation and pump life is 1100 RPM.

LIQUID COOLED MODELS
Liquid cooled models have a water jacket built into the cylinder to cool the pump. The
coolant inlet is in the cylinder housing near the base and there are two coolant return
ports, one on either side of the valve housing above the cylinder.
A temperature gauge kit is supplied with liquid cooled pumps and should be installed at
or near the coolant return port to accurately register pump temperature. If the pump is
connected to the cooling system of a truck engine, the gauges of the truck and the pump
should show similar temperatures. NOTE!
If the two temperature gauges show significantly different
temperatures, coolant is not flowing properly to the pump. Check
for proper installation and possible obstruction of the coolant
hoses.
PUMP LUBRICATION
Rotary Vane Vacuum Pumps require a high quality non-detergent Rotary Compressor
Oil or Rotary Turbine Oil. Oil specifically formulated for Masport pumps is available from
your local Masport representative or by contacting Masport Inc. It can be ordered in one
gallon jugs or six gallon cases and is available in both summer and winter grades.
NOTE!
NEVER use automotive motor oil, it can break down and leave
deposits in the pump that will affect pump life or performance.
Other oils and fluids that should never be used in Masport vacuum pumps are:
USED OIL
TRANSMISSION FLUID
POWER STEERING FLUID
BRAKE FLUID
HYDRAULIC FLUID
GEAR OIL
VEGETABLE OIL

7
All Masport HXL pumps are equipped with automatic gear-driven oil pumps that are
preset at the factory and require no adjustment or maintenance.
OIL RESERVOIR MOUNTING
The oil reservoir tank must be mounted
higher than the oil feed connection on the
oil pump so that oil will be fed by gravity to
the oil pump.
PRIOR TO START-UP
Before running the pump for the first time (and any time after pump teardown or if it has
been out of service for some time) bleed the oil feed line from the reservoir and prime
the oil pump.
Pour 1 to 2 oz. (30 to 60 ml) of pump oil into the vacuum pump inlet and rotate the pump
BY HAND several times to coat the cylinder with a fresh film of oil. After start-up,
observe the transparent oil lines coming from the oil pump to confirm that oil is flowing
from the oil pump to the cylinder ports.
BLEED THE OIL PUMP
Make sure there is adequate pump oil in the
reservoir. Loosen but do not remove the bleed
screw on the oil pump. When oil starts to drip
from the bleed screw, retighten it.
VACUUM RELIEF VALVE
NOTE!
The Vacuum Relief Valve is not set at the factory.
A working vacuum of 22" Hg at sea level is recommended for optimum pump life and
performance. Working vacuum level should be decreased by 1" Hg for every 1000 ft of
elevation. The vacuum relief valve setting should be verified using a quality liquid filled
vacuum gauge.

8
To adjust the vacuum relief valve
Loosen the Jam Nut and adjust vacuum level by
increasing or decreasing spring tension with the
Adjusting Nut. When vacuum level is set
retighten the Jam Nut.
PUMP OPERATING TIPS
•Frequently check the oil level in the oil pump reservoir. NEVER run the pump
without oil.
•Maintain pump speed within the acceptable range (optimal is 1100 ±100 RPM).
Running the pump too fast or too slow may cause damage.
•Engage the pump drive at engine idle. NEVER engage at high RPM.
•Always bleed the tank to atmosphere before switching from vacuum to pressure
or from pressure to vacuum.
•Always disengage the pump when driving to or between job sites.
•Monitor vacuum and temperature gauges to detect any irregularities or problems.
•When using pressure to offload, a pressure relief valve and gauge must be
installed. Avoid over pressurizing the system.
•Drain the scrubber after each load. DO NOT open the ball valve while the tank
still holds vacuum, this may allow debris to enter the pump. If nothing comes out
of the scrubber, never assume it is empty, check for blockage in the valve.
•Drain the oil separator daily. Do not reuse the oil, take it to an appropriate
recycling site.
•Check and clean the pre-filter element regularly.
•Flush the pump daily - refer to the Pump Maintenance section in this manual.
•Never run a liquid cooled pump without circulating coolant.

9
PUMP MAINTENANCE
Masport vacuum pumps require little regular maintenance except for flushing the pump
daily or any time liquid or solids have been allowed to enter the pump.
FLUSHING PROCEDURE
Masport flushing fluid is available from you local Masport dealer or from Masport Inc.
1. Start the vacuum pump and bring it to 15" Hg.
2. Open the ball valve on the reservoir to begin
flushing fluid flow.
3. Run the pump until the fluid level in the tank drops
one gradation on the tank label (7 fluid oz. or
approximately 200 ml).
4. Close the ball valve but continue to run the pump
for one additional minute to ensure that all of the
fluid is purged from the pump.
5. Stop the pump.
6. Drain the oil separator. Do not reuse the flushing
fluid, take it to an appropriate recycling site.
FLUSHING KIT
STORAGE
If the pump is likely to remain idle for an extended period make sure to flush the pump
as described in the Flushing Procedure and run for a minute or two to make sure the
pump is sufficiently lubricated. The pump should be run for a few minutes once a month
to distribute fresh oil to the bearings, seals, and cylinder.
PUMP SERVICE
NOTE!
Any service or repair work on your pump should be performed by a
qualified mechanic with the proper tools and experience working
with vacuum pumps. Contact Masport Inc. if you have questions or
for help finding a certified Masport service facility.
CAUTION!
Disconnect the pump drive to ensure the pump cannot be
accidentally started during service and to allow the shaft to be
rotated by hand.

END COVER REMOVAL
Before removing the cylinder end covers, clean the outside of the pump to prevent dirt
and debris from getting into the cylinder.
Remove the shaft guard and support the end of the shaft so that the rotor will not drop
when the end cover is pulled from the bearing. A notched piece of wood can be used to
support it from below, or a long nipple can be screwed into the valve above the shaft and
a strap can be hung from the nipple to support the shaft.
If you are working from the oil pump end of the
cylinder, start by removing the oil pump guard. The
guard bolts are longer than the other end cover bolts
so their location should be noted.
Disconnect the oil line to the fitting in the end cover and
remove the oil pump. The oil pump mounting screws
are different lengths, so note their locations as they are
being removed.

11
Remove the oil pump drive assembly.
Remove all of the end cover bolts.
Thread two M10 x 50mm bolts into the jacking screw
holes in the end cover. Turn the bolts one or two turns
at a time alternating between the two to back the end
cover away from the cylinder.
Extra M10 X 100mm bolts can be used in the other end
cover holes for guidance and support.
Move the rotor support to the inside so that the end
cover can be removed.

12
NOTE!
There may be Mylar shims between the end cover and the cylinder.
They must be replaced with shims of the same quantity and
thickness. Blue color marking indicates .002 thick shim, Green
marking indicates .003 thickness.
CYLINDER INSPECTION
With the end cover removed inspect the cylinder for damage or corrugation.
Gouges or scoring around the circumference of the cylinder indicates dirt or debris
contamination. If the scoring is less than .005" deep the cylinder can still be used as is.
Corrugation across the length of the cylinder indicates that either the vanes are sticking
in the rotor slots or improper operation of the pump and should be investigated before
re-assembling the pump. If the corrugation can be seen but not felt, the cylinder can still
be used as is.
NOTE!
If cylinder scoring is deeper than .005" or if corrugation can be felt
the cylinder should be bored, honed and the seal gap reset.
VANES
Remove the vane at the bottom of the rotor. Insert the new one by sliding the vane
along the cylinder wall. Rotate each vane to the bottom of the rotor to replace them.
NOTE!
Inspect the vanes being removed (especially the ends) for scratches
or gouges that would indicate foreign material caught alongside the
vane. If there is evidence of inadequate filtration or other improper
operation, correct the condition before putting the pump back into
service.
Install the new vanes in the proper orientation:
Vanes for the 15 and 75 model pumps have a radiused edge. Install them with the
radius in contact the cylinder wall.

13
HXL400 vanes have an offset bevel. Install these vanes with the beveled edge in
contact with the cylinder wall and the leading edge facing in the direction of rotation.
Be sure the vanes slide freely in the Rotor
NOTE!
Make sure the vane is oriented correctly. The chamfered edges of the vane
must be inserted into the rotor. On the HXL400 pump the leading edge of
the beveled side must face toward the rotation.
BEARING INSPECTION
It is difficult to visually determine the condition of a bearing. If there is obvious damage
such as discoloration (bluing) of the bearing or the race, there is definite damage and the
bearing and spacer should be replaced. If there is no discoloration and minimal amounts
of carbon or oil sludge build-up on the bearing cage, it can probably be cleaned in
solvent, blown out with an air hose, oiled and reused.
NOTE!
There is no guarantee that the bearings are not damaged and with
the pump disassembled to this point, it is advisable to replace them.
BEARING SPACER INSPECTION
(HXL400 pumps do not have bearing spacers)
The outer circumference of the bearing spacer should be inspected for signs of contact
with the bore of the endcover bearing housing. If there has been contact, it could be a
sign that the bearing is worn and is allowing contact. The spacer and bearing should be
replaced.
BEARING AND BEARING SPACER REMOVAL
Check the shaft for burrs caused by pulley set screws or any other damage from the
pump drive. Remove the burrs with a flat file or smooth the shaft with 400 grit wet/dry
sandpaper.
Loosen the set screw in the worm gear for the oil pump drive and remove the worm gear
from the shaft.

14
Models with bearing spacers:
Remove the bearing and spacer with a bearing puller.
NOTE!
The bearing spacers are not reusable and must be replaced when
removed.
HXL400 Pumps:
Use the jacking screws in the rotor shaft
flange to lift the bearing away from the flange.
Turn the screws counterclockwise one half
turn at a time to evenly lift the bearing. If the
jacking screws do not loosen the bearing
entirely, use a bearing puller to remove it from
the shaft. Screw the jacking screws all the
way back in after bearings have been
removed.
DO NOT loosen the socket head screws that secure the flange to the rotor.
BEARING AND BEARING SPACER INSTALLATION
NOTE!
The bearing spacers MUST be installed in the correct orientation.
Look carefully at the spacer, note that the hole bored for the shaft is
larger in diameter on one side than the other. The spacer must be
installed on the rotor shaft with the larger bore diameter toward the
rotor. Incorrect installation of the spacer will cause bearing failure
and damage to the pump.
Press the bearing and bearing spacer onto the shaft at the same time or separately.
Apply pressure only to the inner race of the bearing. Pressure on the outer race will
cause damage to the bearing. If a bearing press is not available, a 6” long pipe nipple
just big enough to fit over the shaft and cap can be used to drive the bearing onto the

15
shaft by placing the pipe over the shaft and against the inner race of the bearing. If this
method is used, make sure any dirt or pipe scale is removed from the nipple before use
to prevent contaminating the bearing.
RE-ASSEMBLY
Replace any shims that were present when the end cover was removed. Align the
shim(s) with the pins on the cylinder. Two or three small dabs of grease around the
cylinder face will help hold the shim in position.
Check the endcover o-ring and grease seal for damage and replace them if necessary.
Install the o-ring in the end cover groove.
Small dabs of grease will help retain the o-
ring in the groove.
Apply a small amount of grease to the lip of
the oil seal and fit the end cover over the end
of the shaft. Use caution when installing the
end cover to ensure the seal is not damaged
by the shaft keyway.
Move the rotor shaft support back to the end
of the shaft.
Slide the end cover onto the shaft bearing
and the locator pins. Tap the end cover into
position with a rubber mallet.
Reinstall the end cover bolts and tighten
progressively in a crisscross pattern until all
bolts are torqued to 28 ft-lbs.
Rotate the shaft by hand to confirm the vanes
don't jam and the rotor turns smoothly.

16
If the oil pump was removed, reinstall the
drive assembly. Align the hole in the drive
assembly with the oil inlet elbow and push
the assembly in until it bottoms out.
Engage the drive tang of the oil pump with the slot in the drive assembly and reinstall the
oil pump.
Reconnect the lines from the oil pump to the inlet fittings.
Turn the rotor shaft by hand to make sure it rotates
freely.
Connect the oil reservoir hose to the oil pump and
bleed the line.
To bleed the line, loosen but do not remove the bleed
screw on the oil pump. When oil starts to drip from
the bleed screw, retighten it.
Pour 1 oz. (30 ml) of pump oil into the intake
of the pump valve or into the cylinder oiling
fittings and rotate by hand to distribute the oil.
Reinstall the shaft cover and reconnect the pump drive.
Start the pump and bring it to operating speed. Check for normal operation and that oil
is flowing from the oil pump to the fittings
