Frame - Heavy duty one-piece construction. Grease lubricated. Combination bearing frame and seal housing.
Shaft assembly - One-piece stainless steel.
Liquid end - Back pull-out design allows disassembly without disturbing the suction and/or discharge piping. Two-piece construction.
Casing - Suction head and casing are one-piece casting. Tangential discharge. Rotated at 90° intervals through 360°.
