Double Suction First-stage Impeller reduces NPSHR and often eliminates the need for booster units.

Double Volute Construction for both stages minimizes hydraulic loads in any service condition down to minimum flow.

API 682 Seal Chambers operate at suction pressure and allow for installation of cartridge design single, dual unpressurized and dual pressurized mechanical seals to meet safety and environmental requirements.

Shaft Options include double extension for connection to auxiliary pumps or hydraulic turbines, and special shaft end machining for hydraulic fitted couplings.

Baseplate Designs and Pump Packages engineered to contract requirements.

Dynamic Balancing and TIR Verifications on assembled rotors ensure optimum mechanical performance throughout the operating range.
