INSTALLATION
PIPING - GENERAL
Support both suction and discharge piping independently at
a point near the pump to avoid putting a strain on the pump
housing. Start all piping AT THE PUMP.
Increase pipe diameter at both the suction and discharge by one
(1) standard pipe size (minimum) to obtain desired performance
and flow rate. Refer to Table I when sizing pipe for your pumping
system.
NOTICE: Do not use pipe with smaller diameter on the suction
side of pump.
SUCTION PIPE
Increase pipe size from pump tapping as shown in Table I.
Figure 1 depicts a recommended run of pipe and fittings for
the suction side of a centrifugal pump. Please refer to this

MAINTENANCE
PUMP SERVICE
This centrifugal pump requires little or no service other than
reasonable care and periodic cleaning. Occasionally, however,
a shaft seal may become damaged and must be replaced. The
procedure as outlined below will enable you to replace the seal.
NOTICE: Pumps use mechanical seals with a rubber seat
ring or a sealing O-Ring. THESE SEALS ARE COMPLETELY
INTERCHANGEABLE.
NOTICE: The highly polished and lapped faces of this seal are
easily damaged. Read instructions and handle the seal with
care.
Some models are equipped with an impeller screw, which has
a left hand thread. Before unscrewing the impeller, remove the
impeller screw.
REMOVAL OF OLD SEAL
1. After unscrewing impeller, carefully remove rotating part of
seal by prying up on sealing washer, using two screwdrivers
(see Figure 5A). Use care not to scratch motor shaft.
2. Remove seal plate from motor and place on flat surface,
face down. Use a screwdriver to push ceramic seat out
from seal cavity (see Figure 5B).
INSTALLATION OF FLOATING SEAT (Figure 5C)
1. Clean polished surface of floating seat with clean cloth.
2. Turn seal plate over so seal cavity is up, clean cavity
thoroughly.
3. Lubricate outside rubber surface of ceramic seat with
soapy water and press firmly into seal cavity with finger
pressure. If seat will not locate properly in this manner,
place cardboard washer over polished face of seat and
press into seal cavity using a 3/4” socket or 3/4” piece of
standard pipe.
4. DISPOSE OF CARDBOARD WASHER. Be sure polished
surface of seat is free of dirt and has not been damaged by
insertion. Remove excess soapy water.
INSTALLATION OF ROTATING PART OF SEAL UNIT (FIGURE 5D)
1. Reinstall seal plate using extreme caution not to hit
ceramic portion of seal on motor shaft.
2. Inspect shaft to make sure that it is clean.
3. Clean face of sealing washer with clean cloth.
4. Lubricate inside diameter and outer face of rubber drive ring
with soapy water and slide assembly on motor shaft (sealing
face first) until rubber drive ring hits shaft shoulder.
5. Screw impeller on shaft until impeller hub hits shaft
shoulder. This will automatically locate seal in place and
move the sealing washer face up against seat facing.
Reinstall impeller screw (if used).
