DeScriPtion
This manual contains installation, operation, assembly, disassembly and repair instructions for the
Fristam “FPH & FPHP” pumps. Please read this manual in its entirety before operating the pump.
The FPH & FPHP pumps are mounted to a heavy duty cast iron bearing block. This bearing block is
coupled to a motor and mounted on a solid stainless steel adjustable baseplate.
The motors used on FPH & FPHP pumps are standard NEMA totally enclosed fan cooled (TEFC) mo-
tors. Replacement motors are readily available from local motor distributors.
The open design of the impeller facilitates cleaning. Due to close clearance between the impeller and
the housing and cover, these pumps are very efficient.
Fristam Pumps have an internal mechanical seal which allows the pumped product to cool, lubricate
and clean the front seal. The FPH & FPHP Series have similar operating characteristics to standard
single impeller centrifugal pumps. The unit is NOT self-priming, it requires a flooded suction.
!
DANGER: BEGIN ALL PUMP MAINTENANCE BY DISCONNECTING THE ENERGY
SOURCE TO THE PUMP. OBSERVE ALL LOCK OUT/TAG OUT PROCEDURES
AS OUTLINED BY ANSI Z244.1-1982 AND OSHA 1910.147 TO PREVENT AC-
CIDENTAL START-UP AND INJURY.
Note: Check alignment between
bearing block shaft and motor
shaft before start-up.

The oil level should be maintained to the center of the sight glass on the side of the bearing block. It
is recommended that when the pump is first installed the oil is changed after the initial 20 hours of
operation. After this, the oil should be changed every 2,000 hours or 3 months under normal operating
conditions. Make sure the oil drain pipe and cap are properly tightened to prevent any oil leakage from
the bearing block.

recommended Seal mainTenance
Visually inspect mechanical seal daily for leakage.
Replace mechanical seal annually under normal duty.
Replace mechanical seal as often as required under heavy duty.
elaSTomer inSpecTion
Inspect all elastomers when performing pump maintenance. We recommend replacing elastomers (o-
rings and gaskets) during seal, pump shaft and/or motor replacement. If the impeller nut gasket fails,
the threaded hole on the impeller nut and the threads on the end of the shaft will need to be cleaned. A
wire brush is recommended for cleaning these threads.

unPackinG
Check the contents and all wrapping when unpacking the pump. Inspect the pump carefully for any dam-
age that may have occurred during shipping. Immediately report any damage to the carrier. Remove the
shaft guard and rotate the pump shaft by hand to make sure the impeller rotates freely. Keep the protective
caps over the pump inlet and outlet in place until you are ready to install the pump.
inStallinG
Prior to actually installing the pump, ensure that:
• the pump will be readily accessible for maintenance, inspection and cleaning.
• adequate ventilation is provided for motor cooling.
• the drive and motor type is suitable for the environment where it is to be operated. Pumps intended
for use in hazardous environments e.g., explosive, corrosive, etc., must use a motor and drive with
the appropriate enclosure characteristics. Failure to use
an appropriate motor type may result in serious damage
and/or injury.
• check alignment between the motor and bearing block.
PiPinG GuiDelineS
• Ensuring proper piping support and alignment at both
the suction inlet and discharge outlet can help prevent
serious damage to the pump housing (Figure 1).
• Avoid abrupt transitions in the piping system (Figure 2).
• Avoid throttling valves in the suction piping.
• Keep suction lines as short and direct as possible.
• Ensure that the NPSH available in the system is greater
than NPSH required by the pump.
• Avoid sump areas where sediments may collect (Figure 3).

• Avoid the formation of air pockets in the piping (Figure 4).
•Avoid abrupt closure of shut-off valves, this may cause hydraulic shock which can cause severe dam-
age to the pump and system.
• Avoid elbows in the suction line if possible. When necessary they should be located 5 pipe diameters
away from the pump inlet, and have
a bend radius greater than 2 pipe
diameters (Figure 5).
• Check valves in discharge line
should be a minimum of 5 ft. away
from the pump outlet (Figure 5).
aliGnment
In most cases, the pump will be
shipped with a drive unit mounted on
a common baseplate. The drive and
pump are aligned at the factory; how-
ever, this alignment should be checked
after installation (Figure 6). Misalign-
ment between the pump and drive can
result in premature bearing failure or
other damage. If the pump is not shipped with a drive unit, use a flexible coupling between the pump
and drive unit. Align the pump and drive unit according to the coupling requirements.

cHeckinG aliGnment
Remove the wire ring from the coupling
sleeve and let it hang between the sleeve
and one of the flanges.
To check the parallel alignment place a
straight edge across the two coupling
flanges and measure the maximum offset
at various points around the periphery of
the coupling without rotating the coupling.
If the maximum offset exceeds the figure
shown under “Parallel” in the table, realign
the shafts.
Check the angular alignment with a
micrometer or caliper. Measure from the outside of one flange to the outside of the other (“Y”) at
intervals around the periphery of the coupling. Determine the maximum and minimum dimensions
without rotating the coupling. The difference between the maximum and minimum must not exceed
the figure given under “Angular” in the table. If a correction is necessary, be sure to recheck the
parallel alignment.
Replace the wire ring on the O.D. of the coupling sleeve.

electrical inStallation
We use standard duty TEFC motors unless otherwise specified. Many motor options are available: wash-
down, flameproof, explosion proof, hostile duty or chemical duty.
Have an electrician connect the motor using sound electrical practices. Provide adequate protection.
Pumps fitted with mechanical seals must not run dry, not even momentarily. Determine the direction of
rotation by watching the motor fan, which must turn clockwise.

The selected motor should meet the requirements of the specified operating conditions. A change in
conditions (for example, higher viscosity, higher specific gravity, lower head losses) can overload the mo-
tor. When changing operating conditions or whenever there is any doubt, please contact Fristam Pumps,
Inc., for technical assistance.
PumP oPerationS
Start-uP inStructionS
• Remove any foreign matter that may have entered the pump.
• Do not use the pump to flush the system!
• Fill bearing block with oil, as directed on page 5, before starting the pump.
Check pump for proper rotation as indicated on the pump. Proper motor direction is clockwise when
looking at the fan end of the motor. (NOTE: When checking the direction of rotation, the pump must
be full of liquid.)
• Never run the pump dry, even momentarily. Seal damage can result.
Note: Maximum inlet pressure to the pump should not exceed 600 psi for all FPH models. Maximum
inlet pressure to the pump should not exceed 1000 psi for all FPHP models.
SHut-Down inStructionS
• Shut off the power supply to the pump.
• Close the shut-off valves in the suction and discharge piping.
• Drain and clean the pump as required.
• Protect the pump against dust, heat, moisture and impact damage.
inStallation oF Seal FluSH For Double mecHanical Seal
Set up the seal flush for the
mechanical seal as shown in
(Figure 7). Use only about 12
gallons per hour of water at a
pressure of 1-2 PSI. Excessive
flow of water through the seal
increases the pressure inside
the seal, causing the seal to
wear prematurely.
Pipe the exit side of the water
flush with 2-5 feet physical
height of tubing. This ensures
that some water is always in the
stationary seal and the seal never runs dry.
It is possible to inject steam through the stationary seal (within the pressure requirements). We do not
recommend using steam alone for the cooling/lubricating of the seal.
It is desirable to have the flush water on the outlet side visible. This allows an easy check to see that
the flush water is on, and also if the seal is functioning properly. In a malfunctioning seal the flush
water will disappear, becomes discolored or shows an unusual increase in flow. If these conditions exist,
check the seal and replace if necessary.
