Vanton Pump has introduced a new Sump-Gard thermoplastic centrifugal pump that handles flows to 1,200 gpm (4,500 lpm) at heads to 200 ft (60 m). The model SGK-2700 features all wetted components that are molded of solid polypropylene, PVDF or CPVC to resist chemical attack associated with pumping of process fluids, plant effluents and industrial water and waste streams, while minimizing abrasion.

Since all wetted surfaces are chemically inert, the pumps are also rated for handling reagent grade chemicals, high purity water and other fluids that must remain contamination free. The alloy shaft, which is isolated from fluid contact by a thick-sectioned thermoplastic sleeve, transfers torque from a 125-hp (93-kW) motor and can employ a balanced 14-in. (356-mm) diameter impeller. According to Vanton, the pump’s large-diameter, cantilevered shaft eliminates the necessity for any immersed bearings and permits dependable operation even while dry running.
