Pump Division Bearing Housings with Casing Materials available to suit Casing Design with suction and 360 attachment and unique service conditions include cast iron, discharge flanges in the lower half, fastening to upper and lower ductile iron, ductile Ni-Resist D2, allows access to the rotating element casings provide superior bronze, nickel aluminum bronze, without disturbing piping or driver. bearing stability and shaft carbon steel, 316 stainless steel and Upper casing does not have to be support. Perfect shaft align- duplex stainless steel.

8 Opened to remove and replace ment is assured by a full bearings, packing, mechanical register fit to the casing. seals, sleeves and sleeve nuts. Bearing housings and stuffing boxes can be easily removed and reinstalled. Precision Cast Impeller assures achievement of maximum pump efficiency. Impellers are dynamically balanced to ISO 1940. tolerances. Multiple impeller designs exist for each casing to give maximum flexibility for upgrading pump performance to meet future service conditions. Shaft is conservatively designed to minimize deflection and reduce maintenance costs caused by wear.

9 Wear Rings, positively locked by radial pins, are standard for casing protec- tion. Optional for impeller protection, wear rings are shrinkfit and pinned securely. 5.
