3. DESIGN OF MAJOR PARTS

3.1 Pump Casing (All Pump Types)
The Casing type is Foot Mounted, ISO vertical, Centerline, End Suction, Top Discharge, one piece
solid construction. A wear ring may be mounted in the casing to provide a close running clearance with
the impeller Neck ring.
3.2 Impeller (All Models)
The impeller is a single suction, radial / Mixed flow, closed design. The impeller is dynamically
balanced, keyed to the shaft. Renewable Neck rings can be press fit onto the impeller hubs (front and
back) where needed. Double curvature impeller blades, provide highly efficient suction performance,
higher speed capabilities and greater performance for reduced running costs and maintenance.
Impeller is taper mounted and keyed to shaft and secured by Lock Washer and Impeller nut for
positive locking.
3.3 Lock Washer (All Pump Types)
Lock washers are assembled between impeller and impeller nut. These Lock washers are
manufactured by Nord-Lock. NORD-LOCK is a pair of washers with a wedge-locking action meeting
DIN 25201 which is a unique method using tension instead of friction. The NORD-LOCK bolt securing
system uses geometry to safely lock impeller onto the pump shaft.
3.4 Shaft (All Pump types)
The shaft is made of high grade stainless steel. It is precision machined over its entire length and has
generous fillet radii at each change of section to reduce stress concentrations. Water slinger prevents
intrusion of pumped fluid into shaft bearing.
3.5 Heavy Duty Bearing Housing
The pump has positively located dual bearings.
