Single Case Pumps - Radially Split-WTB

Single Case Pumps - Radially Split-WTB

Made in two- and three-stage designs with top/top nozzles, the Flowserve WTB pump is a between bearings, radially split, volute type process pump engineered to provide safe, reliable operation at elevated temperatures and pressures. To reduce NPSHr, a double-suction, first-stage impeller is standard on all but the two smallest sizes. Featuring hydraulics that fall between that of a typical two-stage BB2 pump and a typical multistage BB5 barrel pump, the unique three-stage WTB is a reliable solution for niche applications in refineries, chemical and petrochemical operations, and power plants.

Features & Benefits

•    Heavy-Duty, Dual Volute Casing With an Integral Crossover ensures radial hydraulic balance and stable performance over the pump’s full operating range.
•    Centerline Supported, Radially Split Design prevents distortion at high temperatures and pressures.
•    Double-Suction First-stage Impeller minimizes axial thrust and significantly reduces NPSHr, often eliminating the need for booster units.
