The ERPN is the pump of choice for severe chemical, petrochemical, refining and heavy-duty industrial service where full compliance with API 610 is NOT required.
Pump Design incorporates a modular system that provides maximum mechanical and hydraulic design flexibility and allows each pump to be customized for an individual application.
API 610 Standards are met for the most critical parameters including vibration limits, deflection limits at seal faces, nozzle loading capabilities, balancing grades.
API 682 Seal Chamber accommodates a wide variety of seal configurations including dual pressurized and unpressurized cartridge types for the most severe services.
Dynamically Balanced, high efficiency impeller limits vibration and assures smooth operation over wide flow range.
Pump Casing and Cover feature metal-to-metal fit with fully confined, controlled compression gasket to ensure proper sealing and alignment.
