4. Install packing gland studs (155), packing gland halves
(152), and gland nuts (156). Tighten nuts finger tight at
this point. Place the O-ring (530) on the shoulder of the
packing housing.
5.
Slide the packing housing into the drive adaptor (10).
Secure the suction housing (100) to the drive adapter (10)
with four hex head screws and lock washers (20/30).
Take care to be sure the o-ring (530) is placed on the seal
housing (140) before assembling.
6. Next, carefully slide the rotating/stator assembly first
through the suction housing (100) and then through the
seal stationary face in the seal housing and over the gear
reducer shaft. Align the holes by rotating the motor fan.
Use a punch to align the holes axially.
7. Replace the drive pin (70) and slide the slinger ring (60)
onto the shaft over the drive pin (70).

protection, the following is advised:
1.
Store pump inside whenever possible or cover with some type
of protective covering. Do not allow moisture to collect around
pump.
2. Remove drain plug to allow the pump body to drain and dry
completely.
3. See drive manufacturer’s instructions for motor and/or drive
storage.
4. See OPERATION, Sections 3-1. through 3-4., before startup.
Be sure all lubricants are in good condition.
Long-Term Storage.
If pump is to be in storage for more than six
months, perform the above short-term storage procedures with the
exception of Step 4. In its place it is suggested that the stator be
removed to avoid developing a “set” condition. In addition: Apply
rust inhibitor to all unpainted cast iron and machined carbon steel
surfaces.
9-1. RECOMMENDED SPARE PARTS
gearbox can be mounted. For units with a double or
cartridge seal please refer to section 7-7 before mounting
the gearbox to the drive adapter.
7-5. Pumps with Single Mechanical Seal
1.
Carefully slide the rotating portion of the mechanical seal
(150) onto the drive shaft up against the set collar (160).
The seal face should be facing out, away from the
connecting rod (460). Apply a small amount of grease to
the ID of the rubber bellows making it easier to slide onto
the shaft.
2. Gently push the stationary portion of the mechanical seal
into the recess in the seal housing (140). Place the O-ring
(530) on the shoulder of the seal housing.
3. Slide the seal housing into the drive adaptor (10).
Secure the suction housing (100) to the drive adapter (10)
with four hex head screws and lock washers (20/30).
Take care to be sure the o-ring (530) is placed on the seal
housing (140) before assembling.
4. Next, carefully slide the rotating/stator assembly first
through the suction housing (100) and then through the
seal stationary face in the seal housing and over the gear
reducer shaft. Align the holes by rotating the motor fan.
Use a punch to align the holes axially being careful not to
damage the mechanical seal.
5. Replace the drive pin (70) and slide the slinger ring (60)
onto the shaft over the drive pin (70)

7-6. Pumps with Compression Packing
1. The standard packing set (150) consists of four braided
packing rings. The lantern ring (151) must be ordered
separately.
2. Wipe a film of lubricant on each packing ring and install
two rings in the packing housing (140). Push each ring
firmly in place, staggering the splits in each ring 90
degrees.
3. Install the lantern ring and the last two rings of packing,
staggering the splits as before.
2. Gently push the stationary portion of the mechanical seal into
the recess in the seal housing and housing plate
(140)(Cartridge seals are self contained.) Insert ro
assemblies in to the seal housing and bolt cover
housing with four cap head screws. Place the O-
