A. Final Pump Assembly
Install the shaft key and any protective guards used over the rotating parts
before reconnecting the pump to its power source.
ALL GUARDS AND PROTECTIVE DEVICES MUST BE INSTALLED BEFORE THE PUMP
IS STARTED. CONTACT WITH UNGUARDED BELTS, SHEAVES, OR COUPLINGS
COULD RESULT IN INJURY.
After making sure all piping connections are snug, adequately supported and
secure, install both the suction and discharge lines then proceed to open all
the valves.
Prior to turning on the pump and power source, check to make sure both
have adequate lubrication to eliminate the danger of friction (see Section F.
LUBRICATION, below).
Finally, take off the fill cover assembly, and pour clean liquid into the pump
casing. Reinstall and firmly secure the fill cover. Refer to Section I.
OPERATION, Part C. Operation, before initiating pump service.
VI.
LUBRICATION
A. Seal Cavity
Take out the vented plug before starting the pump. Use SAE No. 30 oil in the
seal cavity, and fill it to the middle of the sight gauge. For maximum
performance, be sure to keep the oil level in the middle of the gauge at all
times. When adequate lubrication is achieved, clean and reinstall the vented
plug in the seal cavity.
B. Bearing Cavity
Before it was shipped from the factory, the bearing housing was completely
lubricated. Be sure to inspect the oil level regularly to keep it in the middle of
the gauge. Add SAE No. 30 oil through the air-vent hole when more oil is
needed. Be careful to avoid over-filling the oil in the bearing cavity since it
may cause the bearings to overheat. Overheating causes premature bearing
failure and makes early replacement necessary.
