Tormac Horizontal Split Case centrifugal pumps. The single-stage, double suction pumps are intended to deliver higher flow rates at a specified operating head. Axial thrust is eliminated by the hydraulic balance provided by the double suction impeller with a bearing design. The casing is divided axially, with opposing suction and discharge flanges, substantially simplifying maintenance. The lower portion of the casing is cast with the inline suction and discharge nozzles. As a result of this design, it is simple to remove the upper casing and rotational parts without damaging the motor or pipework.
