Centrifugal pump BB3 MSN

wateroilelectric

Delivering high heads and high efficiency for pipeline, boiler feed, refinery and other services Benefits State-of-the-art hydraulic design to increase efficiency and reduce absorbed power Double-flow first stage impeller available to reduce net positive suction head required (NPSHR) Hard coating on all mating surfaces of wear parts to increase durability Features Inlet and outlet flanges integrally cast with the lower half casing Balanced rotor assembly with back-to-back impeller arrangement to minimize residual axial thrust Can operate in reverse mode as a turbine Applications Oil and water pipeline, terminal shipping stations Lean/Semi-lean, amine and gas treatment processes Onshore high-pressure water injection Our MSN/MSND pumps are widely used for heavy-duty service in refinery, petrochemical, oil production, and pipeline applications such as boiler feed, multi-product shipping, water injection, lean and semi-lean processes. They work with a wide range of drivers, including electric motors to steam and gas turbine; and we've even designed pumping trains for use with gas engines upon request. The multi-stage design is double-volute type to balance radial rotor loads at all capacities—thus optimizing unit reliability. The horizontally split case is designed to withstand the highest working and hydrostatic pressures typical for water-injection services. Suction and discharge nozzles are integrally cast with the lower half of the case to permit disassembly of the pump and rotor removal without disturbing the piping connections. Two-row rotors with opposed impellers provide axial balance over the entire operating range.
