WARNINGS & GENERAL GUIDELINES
WARNING: DO NOT paint over any nameplates, ID tags, or warning tags
attached to the pump.
Operating without guards
could result in serious
injury or death. Machinery
in operation can grab,
crush, cut, mangle, and
dismember. Do not
operate without adequate
guards in place.
Over-pressure may burst
pump or system components.
Always include a relief valve in
installation. Do not over
pressurize pump or block
discharge line while operating.
Injection Hazard: Do not try to
stop a leak with your hand!
Avoid any close contact with
hydraulic fluid jets. Escaping
fluid can penetrate skin,
causing serious injury. In case
of accident, seek medical
attention immediately for
removal of fluid.
Hazardous or Toxic fluids can
cause serious injury.

NOTICE: These are general guidelines and do not cover all possible situations. It is the
responsibility of the system integrator to apply this product properly.
System Pressure & Hazardous Fluids
1. Disconnecting fluid or pressure containment components during pump operation can cause property damage,
serious personal injury, or death.
2. Failure to relieve system pressure prior to performing pump service or maintenance can cause property
damage, serious personal injury or death.
3. If pumping hazardous or toxic fluids, system must be flushed and decontaminated, inside and out, prior to
performing service or maintenance.
Plumbing
1. The inlet pipe should be as short and straight as possible to minimize suction pressure losses. Excessive
restrictions at the inlet can cause cavitation resulting in poor performance, noise, vibration, or pump damage.
2. Slope the inlet plumbing appropriately to avoid air pockets.
3. Plumbing weight, misalignment with the ports or thermal expansion can exert excessive force on the pump.
Plumbing must be properly supported and aligned with expansion joints, if required, to minimize these forces.
4. To prevent over pressure situations, install a relief valve as close to the pump outlet as possible. Install the
relief valve before any shut-off valves.
DO NOT use Thread Seal (Teflon®) tape on pump port threads.
Mounting Base
1. Mount the unit on a rigid, heavy base to provide support and absorb shock. Bases should be designed for
high rigidity; not just strength.
2. The pump feet were not designed for mounting to concrete and do not have enough contact area to prevent
concrete from failing. When mounting to cement or concrete, use a steel baseplate to distribute the mounting
stress over an area large enough to prevent the cement from failing. Grout it in place.
Pump and Drive Assemblies
1. Assure adequate guards have been installed to prevent personnel contacting moving components.
2. Follow all OSHA, Federal, State, and local codes.
Check Alignment of Pump to Driveline
Excessive misalignment can overload the pump input shaft and cause premature failure. The figures below show
parallel and angular misalignments.
Figure 1-1: Coupling Alignment

5
Roper Pumps’ Close Coupled Drives
The hydraulic or gearmotor units mount directly to the pump.
oAlignment between pump and driveline is maintained by the assembly.
Because the assembly absorbs reaction forces of the driveline, the mounting base does not need to be as robust.
The level of rigidity and strength is determined by the piping stresses from the system
Guarding PTO Drive Shafts
PTO drive systems can be dangerous and when used, additional safety precautions, including guarding, is
required and must be provided by the drive system installer. Roper Pump Company has no responsibility for
recommending or providing proper guarding or other safety measures in any particular application.
NOTICE: The installation of proper guards for the power take-off and its associated equipment is the
responsibility of the drive system designer and the installer who know the particular product application
and the user’s exposure to danger. The ultimate responsibility for the safe application and
installation is the users.
WARNING: Failure to stop the pump before adjusting the shaft packing can cause
serious injury or death.

PRE-OPERATIONS CHECK
Read and understand the instructions and recommendations contained in this manual.
Disconnect the coupling between the driver and pump.
Test the rotation of the driver to make sure it will operate the pump in the desired direction of rotation. When an
integral relief valve is used, make sure it is positioned and adjusted as discussed on page 17 “TO ADJUST RELIEF
VALVE”. After the unit is mounted and the piping is connected, the pump should be checked to be sure it operates
freely without binding. After operation is proved satisfactory, both pump and driver should be tightly secured and the
alignment rechecked before operation.
Before starting, make sure all guards are in place and the inlet and discharge valves are opened.
After starting the unit, check to see that the pump is delivering liquid. If not, stop the driver immediately and correct
the problem. After the pump is delivering liquid, check the unit for: excessive vibration, localized heating, or excessive
shaft seal leakage. Check the pressure or vacuum by installing gauges at both the inlet and discharge sides of the
pump to make sure the pressure or vacuum conforms to specifications.

PRIOR TO OPERATING THE PUMP, MAKE SURE THAT
THE SHAFT ROTATION, PIPE CONNECTIONS, AND
THE RELIEF VALVE POSITION IS IN ACCORDANCE
WITH THE ILLUSTRATIONS SHOWN.
To reverse rotation, the relief valve must be positioned as shown for desired direction of rotation.
See appropriate instructions to change relief valve position if required.
For inlet pressures over 25 PSIG (1.7 BAR), consult a distributor, district representative or the
home office of the ROPER PUMP COMPANY, COMMERCE, GEORGIA.
LUBRICATION
All lubrication fittings have been greased at the factory. The internal parts of the pump are
lubricated by the liquid being pumped. Outboard bearing or bearing cage should be greased with
ball bearing grease once a month in daily service or equivalent in intermediate service.
RELIEF VALVE
The relief valve must be positioned as shown in instructions for direction of rotation—otherwise
the valve is inoperable and will not give protection.
It is mandatory that the relief valve be set BY THE USER since the maximum relief valve pressure
depends upon the viscosity and specific gravity of the liquid, the flow rate (pump RPM), and also
the initial relief valve setting. If not specified otherwise, the relief valve on this pump is factory set
for full by-pass at a differential pressure of 300 PSIG (20.7 BAR), at a pump speed of 900 to 1800
RPM on liquid with a viscosity of approximately 150 to 300 SSU (28 to 62 centistokes). This
setting would only apply if all these conditions are duplicated. Built-in relief valves sense
differential pressure only (difference between inlet and outlet pressures.)

TO ADJUST RELIEF VALVE
Warning: Take precautions necessary to prevent personal injury or physical damage
That could be caused by any loss of the product being pumped while
Adjusting relief valve.
Relief valve must be adjusted under conditions identical to the operating conditions.
(Viscosity, RPM, etc.)
1. Connect a pressure gauge near the pump in the discharge line between the pump and the
point where the discharge line will be closed. (Most pumps have tapped and plugged
holes in the case near the outlet or in the discharge flange which may be used for this
connection.
2. Remove seal cap and gasket.
3. Loosen the locknut on the adjusting screw.
4. Back the adjusting screw out to the point where the end of the adjusting screw will be at
the max dimension “A” when measured from the relief valve bonnet. See the chart under
the relief valve drawing for the proper dimension.
5. Start pump and close the discharge line slowly. Do not exceed pressure rating of pump or
other equipment between pump and discharge line valve. If this pressure is reached while
closing the discharge valve, do not close any further. (This might occur with very high
viscosity liquids) it would then be necessary to install a separate relief valve in the system
for protection. Do not run pump with closed discharge line for more than two minutes at a
time.
6. With discharge valve closed, turn adjusting screw clockwise in ½ turn increments until the
pressure gauge shows the desired pressure setting.
7. Tighten locknut.
8. Replace the gasket and seal cap.
9. Open discharge line, and turn pump off.
Relief valve is now set.

18
TO REPLACE SPRING/PISTON OR CHANGE DIRECTION OF PUMP
To replace spring and/or piston or to change direction of rotation, shut pump off, remove seal cap
and gasket. Loosen locknut and adjust relief valve pressure to minimum. Remove bonnet and
gasket making sure that the spring pressure does not force bonnet out too rapidly. Remove plug
cap and gasket from faceplate. Check all parts and internal passages to make sure that they are
clean and free from rust or damage. To assemble, determine direction of rotation and replace
plug cap and gasket as shown in direction of rotation. Place poppet and spring in correct position
according to direction of rotation.
Turn adjusting screw to have shoulder flush with bonnet, place spring guide on adjusting screw;
install gasket and assemble into faceplate making sure spring engages over spring guide.
Tighten bonnet. Reinstall gasket and plug cap, if removed. Adjust relief valve pressure as
described.
A built-in relief valve should not be used on applications where the discharge must be closed for
more than a few minutes. Prolonged operation with the relief valve fully by-passing will cause
heating of the liquid circulating thru the valve, thus resulting in possible damage.
CHECK POPPET PERIODICALLY TO MAKE SURE THAT IT WILL SLIDE
FREELY IN PUMP FACEPLATE. FAILURE TO SLIDE DUE TO BINDING OR
FOREIGN MATERIAL WILL CAUSE EXCESSIVE PRESSURE BUILDUP IN
PUMP.

19
MECHANICAL SEAL
Mechanical seals do not require adjustments. Leakage developed at the seal may be due to one
of the following conditions; worn, marred, or cracked rotating or stationary lapped seal faces, or
bellows that has become hard, soft, cracked, expanded or extruded.
When replacing or servicing a mechanical seal, take particular care not to mar or scratch the
sealing surfaces or damage the bellows. If the seal has been used, do not put it back into service
unless both sealing surfaces are perfectly flat and smooth or else replaced.
To replace the mechanical seal on pump size F1 thru F5, remove the key, cap screws, bearing
cage, and gasket. Remove burrs and sharp edges from the end of shaft and keyway and clean
the shaft. Next the seal parts may be removed from the shaft. To assemble, lubricate with a light
machine oil the section of the shaft over which the seal is to be mounted. Slide the rotating
element onto the shaft. Be sure it is properly centered on the shaft. After checking the bearing
cage and lip seal and replacing if required, coat the sealing surfaces with light machine oil. Install
bearing cage and gasket and secure with the cap screws.

20
To remove the mechanical seal on pump sizes F10 thru F300, remove the retaining ring on the
shaft of the F10, or loosen the set screws in the bearing of F15 thru F300. Remove the retaining
ring from the bearing cage. Remove the retaining ring from the bearing cage. Remove the cap
screws and bearing cage. (Bearing and stationary seat will be removed along with the bearing
cage.) Remove burrs and sharp edges from end of shaft and keyway and clean the shaft. Next
the seal parts may be removed from the shaft. To assemble, lubricate with a light machine oil the
section of the shaft over which the seal is to be mounted. Slide the rotating element onto the
shaft. Be sure it is properly centered on the shaft. After checking the stationary seat and “O” ring
and replacing if required, coat the sealing surfaces with light machine oil. Install gasket and
bearing cage and secure with cap screws. Install retaining ring on shaft for F10, or tighten set
screws in bearing for F15 thru F300.
