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 (orings 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.
PI P I N 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.
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.
FM Series Pump

FI G U R E 5
Avoid abrupt closure of shut-off valves, this may cause 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.

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). Misalignment 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 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.
• Reinstall the wire ring on the O.D. of the coupling sleeve.
