Leak Test
(Before oiling pump) Perform a leak test on the pump seals
by installing a regulated air supply into the holes (1/8" NPT
access). The motor chamber, and cover chamber must be
checked. The pressure of the air supply should be set at
approximately 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 (0-15 PSI) air gage can be installed in the fill holes.
The pump to be pressurized and held at 9 PSI. After removing the air supply,
the pressure should not drop more than ½ PSI in a 24 hour period.

1. While pump is on its side pour (18) in motor housing.
Do not over fill.
2.
Clean pipe plugs and reapply pipe dope or teflon tape. Install pipe
plugs (9) in motor housing (11)
3.
CAUTION
Do not operate an unsubmerged progressing
cavity pump. Dry pump operation may damage the hydraulic stator
due to lack of lubrication. Do not run dry.
F. Installing hydraulic stator and pump housing...
1. Place hydraulic stator (28) in pump housing (25)
2. Make sure all 6 stator inserts (29) are in place
3. Place cutter plate (43) on stator
4. Install 6 screws (42) and washers (41)
5. Torque screws to 63-67 in-lbs
6. Cover rotor (22) in red all pupose grease
7. Place square ring (24) in groove, use all purpose grease to hold
in place if necessary.
8. Slide assembled pump housing (25) stator (28) unit over rotor,
rocking back and forth until seated against adapter (19)
9. Install four screws (36). Torque to 125-130 in-lbs
G. Installing the cutter (30)...
1. Install the proper amount of shims (31) on the shaft to obtain the
proper running clearance between the cutter plate (43) and cutter
(44).
2. Install the cutter (44) onto the shaft.
3. Install the screw (40), and flat washer (39) using thread-locking
compound and torquing to 71-75 in/lbs.
Note: Immobilize the cutter by placing a aluminum or brass rod in
one of the holes in the cutter plate.
CAUTION
Do not chip or nick the cutter while using the
rod to immobilize the cutter.
4. With the pump in the vertical position to remove end play, measure
the running clearance between cutter (44) and cutter plate (43)
using a feeler gauge. Repeat 1 thru 3 until .007" to .012" clearance
is obtained. (See cutter clearance diagram on page 4).
