Instead, pump grease into fitting until back pressure occurs, forcing grease into lantern ring to seal
the stuffing box. After priming, when unit is put into
operation, the grease will be flushed out through
the packing by water flowing outward through the
stuffing box. Proceed with normal adjustment of
the packing as described in pump owners manual.
Note that the grease seal is used only for control
of air leakage during priming, and that only the
packing gland is used to control the flow of water

Rotation
Pump Rotation is determined as clockwise or counter-clockwise
by viewing liquid end of pump from the back or shaft side, and
NOT from looking into the impeller eye or front of volute.
Pump Rotation must be verified after installation.
• Electric Motors:
• Note: It is common for many motor and engine
manufacturers to indicate rotational direction in the
opposite manner as the pump standard. That is,
they refer to the rotation as viewed from the front
of motor or engine. Pump rotation is determined
by viewing from the back.
Single Phase: Refer to wiring information on the
motor plate to obtain proper rotation.
Three Phase: If pump runs backward, reverse any
two leads coming off incoming power (L1, L2, L3)
until proper rotation is obtained. (ie: reverse L1
and L2, L2 and L3, or L1 and L3).
• Pump running backward – A centrifugal pump will
still pump liquids, however, GPM and head will be
a fraction of the published performance.

MAINTENANCE
Routine Maintenance
A well maintained pumping system will extend the life of the unit and require fewer
repairs. This means less down-time which can be very critical when a constant delivery
of liquid is required.
A routine maintenance and inspection schedule should be set up on a weekly, quarterly,
and annual basis with records kept of these actions. (Refer to individual pump owner’s
manual for required maintenance and/or lubrication).
Weekly
Observe the following to verify that pump unit is operating properly.
• Vibration – All rotating machines can be expected to produce some vibration.
However, excessive vibration can reduce the life of the unit. If the vibration seems
excessive, discontinue operation, determine cause, and correct.
• Noise – When the unit is operating under load, listen closely for unusual sounds that
might indicate that unit is in distress. Determine the cause and correct.
• Operating Temperature – During operation, heat is dissipated from the pump bearings and the driver. After a short period of time, the surface of the pump bracket will be
quite warm (as high as 150°F), which is normal. If the surface temperature of the pump
bracket or driver is excessive, discontinue operation, determine cause of the temperature rise, and correct. Bearings will run hotter for a brief run-in period after packing
which is normal. However, worn bearings will cause excessive temperatures and need
to be replaced.
The pump unit is cooled by the water flowing through it, and will normally be at the
temperature of the pumping liquid.
• Stuffing Box – After a short period of operation, verify that the stuffing box area and
gland are not hot. If heating is detected, loosen the gland nuts evenly until water is just
running out of stuffing box in a DROPLET form. Water must not be streaming or spraying out. Verify cool operation periodically. Adjust gland nuts EVENLY as necessary for
lubrication and cooling of the packing. If packing has been tightened to the limit of the
packing gland travel, additional packing is necessary.
• Mechanical Seal – Inspect seal for leakage. There should be no leakage at mechanical seal.
• Inspect suction line and/or screen for flow obstruction.
Quarterly
• Pump and Piping Connections – Inspect all system piping connections for leakage or
possible misalignment. Misalignment of pipe connections to the pump will put excessive strain on the pump case and can cause damage to internal components of both
the pump and motor. If stress on the pump case is suspected, adjust pipe supports to
correct. For flange connections, misalignment can be checked by shutting down the
pump, and removing the pipe flange bolts on the pump connections. If the mating
flanges come apart or shift, there is pressure at the connection(s) and adjustments
26
MAINTENANCE
Routine Maintenance
should be made to the piping supports until flanges mate without force. This procedure
can be done throughout piping system.
• Check pump foundation for soundness and see that all hold-down bolts are secure.
• Complete any lubrication requirements as dictated by pump/driver owners manuals.
• Inspect packing or mechanical seal for possible replacement. Examine shaft sleeve, if
present, for wear and replace it if necessary.
• Inspect pumping plant panel for signs of wear (ie: replace pitted contactors, etc., as
needed).
• Check pump and/or motor bearings for signs of wear. Repack or replace as required.
Annual
• Inspect pump and entire pumping system for signs of wear.
• Inspect system valves, screens, etc.
• Check electric motor windings for degradation, rewind if necessary.
• Check pump impeller eye clearance.
• Inspect impeller, volute case, and seal chamber for signs of excessive wear or
corrosion.
27
MAINTENANCE
Spares / Winterizing
Recommended Spare Parts
The number and type of spare parts kept on hand at any pump site is dictated by the
severity of the service in which the pump is used. That is, a pump servicing a golf
course’s sprinkling system should not be down because of a simple case gasket, or a
subdivision out of water because of a failed mechanical seal.
It is recommended that the following spare parts be kept on-site as a minimum back-up
to service pump and reduce down-time. Parts shown do not apply to all models. Check
your model/style against parts breakdown drawing(s) when selecting spares.
• Mechanical Shaft Seal
• Packing set and packing hooks
• Shaft Sleeve(s)
• Impeller wear ring
• All gaskets and O-Rings required for one pump
• Retaining Rings
If having a pump non-operational has severe consequences, a back-up pump should be
considered. Otherwise, a back-up impeller, volute case, bearings and shaft, would be
prudent.
Winterizing
If pump is to be out of service for an extended period of time, such as the winter months,
the following storage procedures should be followed.
• Remove exterior dirt and grime or any substance that may trap moisture. Exposed
metal is subject to oxidation, prime and repaint if necessary.
• Flush suction and discharge lines. Check for leaks at this time and replace any worn
gaskets.
