Vanton Pump”s SUMP-GARD model SGK-2700 thermoplastic centrifugal pump handles flows to 1,200 gpm (4500 lpm) at heads to 200 ft (60 m). All wetted components are molded of solid Polypropylene, PVDF or CPVC to eliminate chemical attack associated with pumping of process fluids, plant effluents and industrial/municipal 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. The pump”s large-diameter cantilevered shaft eliminates the necessity for immersed bearings and permits dependable operation for short or extended periods of dry run operation, with no damage to the pump. Vanton also offers other vertical pump configurations, a line of horizontal centrifugal thermoplastic pumps (including sealless magnetically driven pumps), and sealless peristaltic pumps as well as integrated non-metallic tank/pump systems.
