UPPER ROTARY SEAL COMPONENT
PLACEMENT DIAGRAM
(Lower rotary seal is same except impeller hub
serves as spring holder and snap ring)
3. Apply 80-90 weight gear oil to the shaft and to the inside diameter of the
rotating section of rotary seal (36). Push the rotating section onto the shaft in
a continuous motion until the seal faces meet.
4. Install the spring and spring holder over the shaft and seat against the
rotating section. Compress the spring as necessary and install retaining
ring (37) in the groove of the motor shaft.
5. Lightly oil and install seal ring (38) on the seal retainer (39).
6. Press the seal retainer (39) into the adapter (34) and secure with the eight
socket head screws (40).
7. Install the seal seat and rotating section of the lower rotary seal assembly
(41) into the seal retainer (39) in the same manner described in steps 2 and 3 above.
H. Installing the impeller...
1. Install the spring of the lower rotary seal on the exposed end of the rotor/
shaft.
NOTE: Spring holder not required on lower rotary seal.
2. Install the proper number of impeller shims (42) on the shaft to give the face
of the impeller (44) a clearance of 0.038 to 0.076 cm (0.015 to 0.030 in) with
the wearing face of the pump housing (48) (see impeller clearance diagram.)
3. Install the square key (43) in the groove in the shaft.
4. Install the impeller (44), impeller washer (45) and lock washer (50). Secure the
impeller (44) by immobilizing it. Using a pipe wrench, grip the vanes and
install the impeller bolt (46) in the end of the shaft.
NOTE: Apply thread locking compound to impeller bolt (46) before installing.
5. Install the adapter (34) on the pump housing (48), securing it with the eight
screws (32) and lock washers (3).
Leak Test
(Before oiling pump) Perform a leak test on the pump seals by installing a regulated
air supply into the holes (¼" NPT access) the motor chamber, seal chamber and cover
chamber must be checked. The pressure of the air supply should be set at approximately
0.633 Kg (9 psi). Submerge the pump in clear water watching for small air bubbles around
square ring seals, rotary seal, cord connection, and oil fill plugs.
NOTE: Make certain that the pump is placed in the water so that no areas are
present that would trap air (such as the cavity around the lower rotary seal), not
allowing the bubbles to rise to the water surface.
If it is not possible to leak test the pump using the submersion method, a regulated air
supply with a 0-1.055 Kg (0-15 psi) air gage can be installed in the fill holes. The pump to
be pressurized and held at 0.633 Kg (9 psi). After removing the air supply, the pressure
should not drop more than 0.035 Kg (½ psi) in a 24 hour period.
I. Oiling and final assembly...
1. After leak testing has been completed, clean pipe plugs and reapply pipe
dope or Teflon tape. Install pipe plug (1) in cover (4).
2. The following electrical tests
must
be performed:
a) Using a Hypot or Megger, test all leads to case ground.
b) Check that there is continuity from the ground wire(s) to ground.
c) Check that there is no continuity from all lead wires to ground.
d) Check that there is continuity between the thermosensor wires,
e) Check that the resistance between moisture sensor wires is 330K ohms.
3. With the pump laying on it’s side with the oil fill hole up fill the seal chamber
cavity with an anti-wear non-detergent, rust inhibiting, paraffining oil of
approximately 100 SUS. (See table below for acceptable type of oil.)
Refiner
Product Name
Arco
Duro 22 or 32
Exxon
Teresstic 22 or 32 or acceptable equal
Chevron
Clarity Hydrolic Aw ISO22 or ISO32
4. Clean pipe plugs (1) and reapply pipe dope or Teflon tape. Install pipe plug in
adapter
(34).
5. While pump is on it’s side place approximately one quart of oil in motor
housing (17) (Use the same oil as used in the seal cavity.)
6. Set the pump upright and finish filling the motor chamber (17) with oil until it
runs back out the fill hole. With the oil running out the fill hole, the oil will be at
the proper level for the top bearing.
Do not over fill.
7. Clean pipe plug (1) and reapply pipe dope or Teflon tape. Install pipe plug in
motor housing (17).
