Pump Casing and Cover features metal to metal fit with fully confined, controlled compression gasket to endure proper sealing and alignment.

Dynamically Balanced Precision Cast Impeller limits vibration and ensures smooth operation over a wide flow range. An anti-rotation impeller nut positively locks the impeller to the shaft without exposing its threads to the pumped fluid.

API 682 Seal Chambers allow for installation of cartridge style single, dual unpressurized and dual pressurized mechanical seals to meet required safety and environmental requirements.

Modular Design with a range of impeller and casing designs allows the hydraulics to be tailored to the service requirements.

Thrust Pot with API 40° angular contact bearings in back-to-back arrangement enables standard (non thrust) electrical motors to be used and fulfills API 610 bearing life criteria..
