AS, AC Series Vertical Mult-stage Centrifugal Pump The AS and AC series are high-efficiency vertical mult-stage centrifugal pumps designed for energy-saving liquid transfer using impeller-driven centrifugal force. Key components include a main shaft, impeller, guide vanes, pump casing, mechanical seal, and motor. These pumps function as booster pumps, suitable for standalone use or integration into building/industrial pressure systems. Their inline pipeline design allows seamless installation in horizontal piping with matched inlet/outlet diameters, optimizing space efficiency. Installation flexibility includes vertical or horizontal placement; horizontal installations require stabilizing fixing modules for operational reliability.
