Description
Form L-0100R

It is permissible to mount the torque arm with the chain in
the down position. To do this, mount the arm to the pump in
the reverse position. Do not use the tension spring or chain.
WARNING: Do not attach torque arm to movable
linkages.
Figure 1
7. Make certain that the power source conforms to the
requirements of your equipment.
8. Provide adequate protection in guarding around the
moving parts such as the shaft and pulleys.
9. Disconnect power before servicing.
10. Release all pressure within the system before servicing
any component.
11. Drain all liquids from the system before servicing any
component.
12. Check all hoses for weak or worn condition before each
use. Make certain that all connections are tight and
secure.
13. Periodically inspect the pump and the system
components. Perform routine maintenance as required
(see Maintenance section).
14. Never operate a gasoline engine in an enclosed area.
Be sure the area is well ventilated.
15. Use only pipe, hose and fittings rated for the maximum
psi rating of the pump.
16. Never use these pumps for pumping water or other
liquids for human or animal consumption.
1. Use a Pressure Relief Device on the discharge side
of the Pump to prevent damage from pressure
buildup when the pump discharge is blocked or
otherwise closed and the power source is still
running.
2. WARNING: Never pump flammable or explosive
fluids such as gasoline, fuel oil, kerosene, etc. Never
use in explosive atmospheres. The Pump should be
used only with liquids compatible with the Pump
component materials. Failure to follow this warning
can result in personal injury and/or property
damage and will void the product warranty.
3. Never pump acids (i.e. acid fertilizer) with Super
Rollers! When pumping acidic fertilizer, Hypro
recommends only the Silver Series castings and Teflon
rollers, or use one of Hypro's poly centrifugal pumps.
4. Never run the pump faster than maximum
recommended speed.
5. Never pump at pressures higher than the maximum
recommended pressure.
6. Never pump liquids at temperatures higher than the
recommended maximum temperatures (140˚ F / 60˚ C).
engine for additional information. Read all safety information
before attempting to install or operate the pump.
This manual will cover the installation of the basic drive
configurations available for Hypro roller pumps. Consult the
recommendations of the manufacturer of your motor or
The preferred method for mounting the torque arm and
pump to a tractor is with the chains going up to provide
support for the pump (see Figure 1). Attach the torque arm
to the pump with the long side of the arm on the inlet side of
the pump for this type of mounting. Many tractors do not
have easy attachment points for securing the tension and
torque chains. It may be necessary to drill holes in the
tractor's master shield to attach the chains.
It is also acceptable to mount an angle iron on the master
shield to attach the chains.The chains should be attached to
the tractor as close to vertical as possible to avoid a bending
force on the pump.
1. Mount the pump and torque arm to the PTO shaft using
a Hypro series 1320, 1321 or 1323 coupler.
2. Attach the torque chain to the tractor frame with arm in
horizontal position.
3. Attach the tensioning chain to the tractor frame while
applying tension to the spring.

Belt and pulley drive systems are typically used to reduce
pump speed. For determining proper pulley sizes, use the
formula below as a guideline and use “A” or “B” section
belts.
MOTOR RPM FLOW (@ RATED SPEED) PUMP PULLEY DIA.
PUMP RPM FLOW (DESIRED) MOTOR PULLEY DIA.
EXAMPLE: Use a 1725 RPM electric motor to drive a
pump at 950 RPM.
Typically, a pulley diameter on the motor is 3.4 inches. The
pump pulley diameter can be determined from the formula
above:
1725 PUMP PULLEY DIAMETER
950 3.4 INCHES
1725 X 3.4 INCHES = 6.2 INCHES
950
1. Install pulley or bushing/sheave combination (See
Figure 5) onto pump and motor shaft. Mount pump next
to the motor making sure pulleys are lined up properly
(See Figure 6 for proper pump and motor orientation).
Use a straight edge as shown. Rotate to check for run-
out and bent shafts.
2. Make sure belts have proper tension—belts too tight will
cause bearing wear and belts too loose will cause
slipping. (See Figure 7).
3. The rotation on the 4000 series roller pump is gas-
engine-rotation, opposite from the standard roller pump.

6. A strainer should be installed in the suction line. Clean
the strainer as soon as it becomes clogged.
7. Never attach an agitator or any restriction to a
bypass line of a pressure relief device because
system damage may occur.

NOTE: Use only pipe, fittings, accessories, hose, etc.
rated for the maximum pressure rating of the pump.
1. Select adequate size drive unit to avoid overloading.
Avoid unnecessary restrictions in the line such as
elbows, check valves, and all extraneous curves and
bends.
2. Avoid using looped sections of tubing or pipe which
might permit air to become trapped.
3. Use pipe joint sealant on pipe threads to assure
watertight connections.
4. Selection of the right type and size of hose is vital to
good performance. Be sure to hook up the lines to the
proper ports on the pump.
5. Always use a good quality suction hose (one or two
braid reinforced hose to prevent collapse) of at least
the same diameter as the inlet port of the pump. If
the suction (inlet) hose is more than four feet long,
then use the next larger size.
air. Make sure line strainer is free of debris. If pump does not
self-prime disconnect suction hose, fill with water and
reconnect to liquid source.Often a squirt of oil into the ports
of the pump will seal clearances and help priming.
Care of the Pump
Hypro roller pumps are all carefully machined to close
tolerance—high pressure operation depends on close-fitting
parts.Proper care and maintenance will keep your pump
wear at a minimum and will keep it running smoothly and
trouble-free for a long time.
WARNING: Never pump corrosive or abrasive liquids as
these will cause rapid wear or deterioration of body, rotor,
shaft and seals in the pump.The pump should be used only
with liquids compatible with pump component materials.
Never exceed maximum specified rpm and pressure. Never
run pump dry.Failure to follow this warning will void the
product warranty.
Priming the Pump
To help prime the pump keep the inlet or suction line as
short as possible with a minimum of bends, elbows and
kinks.Make sure all connections are tight and do not leak
When direct driving Hypro roller pumps with flexible
couplings make sure that the speed (rpm) of the gas engine
or electric motor is within the maximum rated rpm of your
pump. Also make sure that shaft rotation is correct between
the pump and the motor or gas engine (See Figure 8).
1. Mount motor or engine into position on base.
2. Lineup pump shaft with straight edge as shown in
Figure 4 to assure they are aligned. Shim pump if
necessary to match shaft height of engine or motor.
Shaft ends should not touch.
3. Mark exact position of pump on base — remove and
install coupling halves on both shafts. Place coupling
center disc into one of the coupling halves.
4. Reposition pump, sliding coupling halves together.
NOTE: No end thrust should be applied to pump when
coupling is connected.
5. Tighten pump mounting; then, tighten the set screws on
each coupling.

SLANTED SLOT Rotor
SCOOPED Rotor
Standard NON-SCOOP Rotor
1. Determine the Rotor Type of your Pump by referring to
exploded drawing on the parts list. The three types of
Rotors are NON-SCOOP, SCOOPED, and SLANTED
SLOT.
2. Follow the steps listed in Repair Instructions for
disassembly of the Pump.
3. If your Pump has a NON-SCOOP Rotor (4001, 4101,
6500, 7560) it can be reversed merely by turning the
Rotor/Shaft Assembly around intact (without changing
the position of the Rotor on the Shaft). Reassemble the
Pump with the driving end of Shaft out the Endplate
Side of the Pump. (Standard Pump Rotors are driven
from the Body Side.)
4. If your Pump has a SCOOPED Rotor (1200, 1500,
1700) or a SLANTED SLOT (7700) Rotor follow the
following steps for reversing the Shaft in the Rotor.
a. Loosen and remove the Rotor Set Screw.
b. Press the Shaft out of the Rotor.
c. Reassemble the Shaft and Rotor with the driving
end of Shaft on the opposite side of the Rotor from
standard assembly.
d. Before installing the Rotor on the Shaft, be sure it is
positioned in the correct location on the Shaft
(diameter of Shaft is slightly larger at Rotor
position). Center punch the Shaft through Rotor Set
Screw hole. Then with a drill smaller than Set Screw
— spot drill Shaft so that Set Screw will hold
securely. (Don't drill too deep — just enough so Set
Screw will bite into Shaft).
e. Reassemble the Pump with driving end of Shaft
extending out of endplate side of Pump. (The
standard Pump Rotor is driven from the body side.)
Remember, the Rotor position remains the same —
the Shaft only is reversed — “end for end”.
Note: Configuration is opposite from above for 4001 and
4101 series.
Flush the Pump After Each Use
One of the common causes of faulty pump performance
is “gumming” or corrosion inside the pump. This
prevents the rollers from moving freely in their rotor
slots. Flush the pump with a solution that will neutralize
liquid pumped, mixed according to manufacturer's
directions.
To Prevent Corrosion
After cleaning pump as above, flush it with a 50-50 solution
of permanent type automobile antifreeze (containing a rust
inhibitor) and water. A rust inhibitor such as Fluid Film
(Hypro Part No. 2160-0010 ) can also be squirted into the
ports of the pump. Turn shaft several times to draw
protective liquid through pump and coat entire inner surface.
Drain pump and plug ports to keep out air during storage.
For short periods of idleness noncorrosive liquids may be
left in the pump, but air must be kept out. Plug ports or
seal port connections.
Rotation
Pump rotation must be the same as shown by the arrows on
the pump. Facing the shaft end of the pump, the suction port
is on your left and the shaft must turn counterclockwise. If
reverse rotation is desired, rotor and shaft assembly must be
reversed so that the shaft extends through the endplate. See
Reversing Rotation Section below for proper procedure.
Note: Configuration is opposite for 4001 and 4101 series.

6. With the Rollers exposed, remove them – examining
each one carefully for excessive wear. When replacing
damaged Rollers always replace the full set.
7. To remove the Rotor with Shaft from the End Plate –
support the End Plate in an Endplate Support Fixture
with the Rotor down. Center the Bearing Disassembly
Tool or 3/8" bolt, on Pump Shaft. Apply pressure to
press Shaft out of Ball Bearing (See Figure 14).
8. To remove the Ball Bearing – place the End Plate in a
Endplate Support Fixture with the front of the End Plate
down (See Figure 15). Center Bearing Support Tool and
slowly press Bearing out of Casting. Repeat procedure
to remove Bearing from Pump Body (See Figure 16)
using Body Support Fixture.
9. After removing the Ball Bearing, check the Seals in both
End Plate and Pump Body. If wear is evident or leakage
has been noticed, punch the Seals out with a
screwdriver and hammer. Seals cannot be removed
without damaging them.
10. To press the Shaft out of the Rotor, first carefully wash the
Rotor and Shaft with kerosene – removing all traces of rust
and other foreign matter. Use steel wool or emery cloth,
rinsing parts afterward to wash off all emery dust. Remove
the Allen Set Screw. Support the Rotor in the press
through the slot in the Base and press Shaft through.
To Take the Pump Apart
1. Remove the Adapter from the Pump Shaft.
2. File off any burrs on the Pump Shaft.
3. Using a screwdriver, pry off the Bearing Cover on the
End Plate and Pump Body
4. Remove the End Plate Bolts.
5. Support the Pump at its Ports in an Endplate Support
Fixture with the End Plate down. Use wood blocks for
Series 1500, 1700 and 4001/4101. Place on press bed.
Center press on Pump Shaft and apply pressure to
press the Pump apart. (See Figure 13).
While the Pump is Apart
Carefully inspect all parts for wear, such as:
• Undersize or swollen Rollers in both length and diameter.
• Worn Seals.
• Worn Shaft at drive end, and pitted or grooved at the seal area.
•Rough Bearings and loss of grease from the Bearings.
•Undersize Rotor and/or worn Roller Slots.
• Excessive wear in Body – both on inside diameter and at back
face.
• Body cracks at the bolt holes and at the O-ring sealing area.
•End wear (Body, Endplate, and Rotor).
•Proper size O-ring in the End Plate.
After the above parts have been checked and the various
points have been considered, you can decide if the Pump is
repairable. When worn parts have been replaced, always
take up the end clearance by lightly sanding the End Plate
and matching body surface (See Figure 17). NOTE: End
clearance should not be more than .004 inches.
Inspect Inside of End Plate
If a groove is noticeable, the End Plate should be resurfaced
by rubbing it on a sheet of 80 grit emery paper (placed on flat
surface) until all trace of wear has been removed. Rotate the
End Plate frequently to remove evenly the same amount of
metal over the entire surface. NOTE:This surface of the End
Plate must be perfectly flat. If attempt has been made to
pry Pump apart with a screwdriver file off all nicks, burrs
and other damage marks around the bolt holes.

Figure 18
NOTE: If the End Plate has been resurfaced the Body face
must also be resurfaced to allow for material taken off the
End Plate.Follow same procedure as above with emery
cloth. Before new parts are installed all burrs should be
removed – particularly in the Rotor Slots and Body.
Do not machine clean the Body Casting. A more
satisfactory job can be done by hand cleaning with an
emery cloth. Wettable talc powder mixture (5 lbs.
powder to 5 gallons water) can be used for breaking in a
repaired Pump if Pump appears to be binding. Run
Pump for about 5 minutes. This will also serve to clean
and remove corrosion from the Pump. Follow with a
clear rinse and protect from rust. (See Maintenance.)
2. Remove the assembled portion from the arbor press and
invert it on the press table with the Bearing Support Tool
under the Bearing. Then place Rollers in the Roller Slots as
close to center of Rotor as possible. Place the Pump Body
over Rotor and Shaft and carefully ease the end of the Shaft
past the lips of the Seal in Pump Body (Figure 21). Center
Bearing Support Tool with counter bored end down on inner
race of Ball Bearing, and slowly press the Pump Body down
to fit the End Plate (Figure 22).
3. Turn Pump over; line up bolt holes and replace Assembly
Bolts. Alternately and evenly tighten the Bolts as shown
(Figure 23). NOTE: After Bolts have been tightened, check to
see if Rotor is centered in Pump Case. Try to turn the Pump
shaft, using a crescent wrench on the Shaft as a lever.
2. If this fails to center the Rotor to where it can be turned
freely — tap other end of Shaft, protecting it as above.
When the Shaft can be turned by hand — using wrench
as above — it is not binding.
3. If the Pump binds within and tapping does not free it, it
may be necessary to “run the Pump in” to wear off high
spots. Use talc solution mentioned earlier. Check Pump
frequently during run in.
Assemble Rotor & Shaft To Endplate
1. Install the Shaft Rotor Assembly by carefully pushing the
short end of the Shaft Rotor Assembly through the Shaft
Seal into the End Plate.Place in the arbor press with the
drive end of the Shaft pointed down. Use the Bearing
Support Tool on top of the Bearing and press the assembly
together. (Figure 20). Leave just enough clearance between
the Rotor and End Plate so that Rotor can be turned by
hand. If it turns too freely, sand a little more off the Body end
that faces the End Plate.You should notice a slight drag, but
be able to turn Shaft with an adapter on it, by hand. The
“slight drag” will wear off after the Pump has been used a
short time. Installing new Rollers, Seals, Bearings, and
Shafts will not prove entirely satisfactory for volume and
pressure unless end clearance is taken up.
Re-Assembly
Replace Seals and Bearings
Carefully place the Seal in the Pump Body with crimped side
down. Press the Seal to the bottom of the cavity, using the
stepped end of the Bearing & Seal Assembly Tool (Figure
18). Then put the Bearing in position in the Pump Body and
press into place with counter bored end of Bearing & Seal
Assembly Tool (Figure 19). Repeat the above procedure with
the End Plate. Seat the O-ring in the groove. If necessary,
make sure the O-ring stays in place by stretching it.
Center Rotor in Pump Case
If pump turns hard:
1. Place short brass rod (or hardwood dowel) against end of
Shaft (Figure 24). Center rod on Shaft (not on Bearing).
Tap lightly with hammer.Try turning Shaft again.
