ANSI Process Pump — ACP Series
ANSI B73.1M centrifugal process pumps with investment casting, up to 350 m³/hr flow, 150 m head, and 25.5 Bar for chemical, pharma, and industrial applications.
The ACP Series is a range of horizontal centrifugal process pumps designed to the ANSI B73.1M standard. Manufactured through state-of-the-art investment casting, the pumps deliver reliable performance for handling low-viscosity, clean or slightly contaminated liquids across chemical, petrochemical, pharmaceutical, food, textile, and industrial process applications.
With a maximum capacity of 350 m³/hr, head up to 150 m, working pressure of 25.5 Bar, and a temperature range of −210 to 260 °C, the ACP Series covers a wide hydraulic field. The fully open impeller design with back vanes reduces hydraulic loads on the stuffing box and sealing, while the CFM/CFD-optimised suction geometry ensures optimum NPSH with near-zero flow distortion.
The modular back-pull-out design allows quick access to the impeller, stuffing box, and housing without disturbing piping or the motor. Oversized shafts with double-row thrust bearings and IP66 bearing isolators extend bearing life by up to 40%, while shaft deflection is held below 0.05 mm at seal faces.
Available in a wide selection of materials — including industrial, food-grade, pharmaceutical, and petroleum-standard approved metals — with shaft sealing options from gland packing to balanced cartridge double seals, the ACP Series handles most process pump duties with maximum interchangeability between variants.
Key features
