This manual contains installation, operation, assembly, disassembly and repair instructions for the Fristam
FM multi-stage pump.
The motors are standard NEMA totally enclosed fan cooled (TEFC) motors. These motors do require feet.
Replacement motors are readily available from local motor distributors.
CAUTION: BEGIN ALL PUMP MAINTENANCE OPERATIONS 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 ACCIDENTAL START-UP AND INJURY.

Visually inspect mechanical seal daily for leakage.
Replace mechanical seal annually under normal duty.
Replace mechanical seal as often as required under heavy duty.
el A s T o m e r in s P e c T i o n
Inspect all elastomers when performing pump maintenance. We recommend replacing elastomers (o-
rings and gaskets) during seal, pump shaft and/or motor replacement.
lu b r i c A T i o n
The oil level should be maintained to the center of the sight glass on the side of the bearing block. 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.
mo T o r mA i n T e n A n c e
Consult motor manufacturer for recommended maintenance.

Check the contents and all wrapping when unpacking the pump. Inspect the pump carefully for any
damage 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.
IN S T A L L I N G
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 (i.e. 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.
PIP IN G GU I D E L I N E S
This section describes good piping practices to obtain maximum efficiency and service life from your
pump.
Maximum performance and trouble-free operation require adherence to good piping practices.
FI G U R E 1
Ensuring proper piping support and alignment at both
the suction inlet and discharge outlet can help prevent
serious damage to the pump housing.
FI G U R E 2
Avoid abrupt transitions in the piping system.
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.

FM Series Pump

FI G U R E 3
Avoid sump areas where sediments may collect.
FI G U R E 4
Avoid the formation of air pockets in the piping.
FI G U R E 5
Avoid abrupt closure of shut-off valves, this maycause hydraulic shock which can cause severe damage
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.
Check valves in discharge line should be a minimum of 5 ft. away from the pump outlet.

* The “Y” dimension is shown for reference.
AL I G N M E N T
In most cases, the pump will be shipped with a drive unit mounted on a baseplate. The drive and pump
are aligned at the factory; however, this alignment should be checked after installation (Figure 6). Mis-
alignment 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.
To check the 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 anges and mea-
sure the maximum offset at various points around the periphery of the coupling without rotat-
ing 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. Deter-
mine 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.
• Reinstall the wire ring on the O.D. of the coupling sleeve.

Set up the water flush for the double mechanical seal as shown.Use only 3-12 gallons per hour of
water at a pressure of 1-2 PSI. Excessive seal pressure and/or flow rate through the product seal cav-
ity may cause increased seal wear and shorten seal life.
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 center seal and the seal never runs dry.
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, become discolored, or show an unusual increase in flow. If these conditions exist, check
the seal and replace if necessary.
el e c T r i c A l in s T A l l A T i o n
The size of the motor selected should meet the requirements of the operating conditions. A change in
conditions (for example, higher viscosity, higher product specific gravity) can overload the motor. For
technical assistance regarding operating condition changes, please contact Fristam Pumps.
Have an electrician connect the motor using sound electrical practices. Ensure that proper motor
overload protection is provided.

• Remove any foreign matter that may have entered the pump. Do not use the pump to ush the
system.
• Before adding oil to the bearing block check the oil drain pipe and cap to make sure they are both
properly tightened to avoid any oil leakage from the bearing block. Fill the bearing block with oil
to the center of the sight glass on the side of the bearing block (see pages 4 & 5).
• Make sure the pump is ooded with product before start-up. The pump must not run dry, even
momentarily.
• Make sure the pump is running in the proper direction. The motor fan must turn clockwise
when looking at the end of the motor.
