4-1 SUBMERSIBLE PUMP
4-1.1 Setting the Pump.
Check to see that the end of the drop hose is cut square. Use a sharp knife or hacksaw to cut the hose if
Install the hose coupling into the end of the drop hose. (Refer to figure 4-1).
If insertion of the coupling is difficult, a small slit (maximum 1 inch) may be made in the end
of the hose. DO NOT use any form of lubrication on hose or coupling.
Push the hose fully on shank of coupling. The end of coupling may be tapped lightly on a wood surface if
Use a sharp knife and cut away about 6 inches of the cable ridge from the hose. File any upstanding part of the
ridge until flush with hose cover.
The coupling clamp contains a grooved portion on the inside. The grooved portion should be
located toward the coupling.
Assemble the coupling clamp onto hose and install the screws. Tighten the screws evenly then, using a torque
wrench, tighten screws to 4.4 ft.-lbs.
The clamp halves may not close completely. A maximum gap of 1/32 inch is acceptable. If
halves close completely before screws are tight, loosen screws and reposition clamp higher
on coupling taper.
Install nipple in check valve, then check valve to hose coupling. Attach hose assembly to submersible pump.
Loosen both nuts of the hose elevator clamp and move the swing bolt aside. Position the clamp half with the
lifting loop to the side of drop hose opposite the cable ridge.
Close the hose elevator clamp on hose and reposition swing bolt. Tighten both nuts finger tight. Be sure the
hose is square and centered in the clamp.
