Split Case Pump

ACO Engineering Pumps Split Case Pumps are horizontal, single-stage, double-suction centrifugal pumps designed for high-volume water transfer applications. The horizontally split casing allows for easy access to the internal components without disturbing the suction and discharge piping. The double-suction impeller design balances axial thrust, providing smooth and reliable operation even at high flow rates. Built with heavy-duty cast iron or stainless steel construction, these pumps are ideal for large water supply systems, irrigation, cooling water circulation, and industrial process applications.
