Flowserve - Nuclear Vertical Multistage Pump

This nuclear vertical multistage pump is engineered for chemical and volume control system charge service in boiling water reactors (BWR), pressurized water reactors (PWR), and pressurized heavy-water reactors (PHWR). Designed to meet ASME Section III, Class 2 and 3 standards, it features suction and discharge connections compatible with AREVA piping requirements. The robust outer casing is built for full working pressure, while the internal assembly includes a crossover to reduce hydraulic thrust and extend bearing life. A standard cartridge seal minimizes maintenance time and exposure, and an optional bearing housing allows the use of standard electric motors. The four-piece spacer coupling enables maintenance of bearings and seals without removing the motor.
