Goulds Pumps Pump NM 3196

WARNING: Pumps are shipped without oil. Oil lubricated bearings must be lubricated at the job site.

Remove fill plug (113A) and add oil until level is at the center of the sight glass (319). Replace fill plug (Fig. 34)

Enter the operating hours of the bearings

Change the oil after 200 hours for new bearings, thereafter every 2000 operating hours or 3 months (whichever comes first).

Check if the Finned Tube oil cooler is present

Sign off on the oil change procedure

Warning: Ensure cleanliness to avoid impurities entering the bearing housing.

Grease container, greasing device, and fittings are clean

Dirt wiped from grease fittings

2 grease relief plugs (113) removed from bottom of frame

Both grease cavities filled with recommended grease until fresh grease comes out of the relief holes

Grease relief plugs (113) reinstalled

Frame seals are seated in bearing housing

Frame seals pressed in place with drains located at the bottom if not seated

Note: Bearing temperature usually rises after regreasing due to excess supply of grease. Temperatures will return to normal after pump has run and purged the excess from the bearings, usually two to four hours.

Check the foundation and the hold-down bolts for tightness.

If the pump has been left idle, check the packing. Replace if required.

Oil should be changed at least every 3 months (2000 hours) or more often if there are any adverse atmospheric conditions or other conditions which might contaminate or break down the oil. If it is cloudy or contaminated as seen by inspection through the sight glass, it should be changed immediately.

Check the shaft alignment. Realign if required.
