Bearingless Sump Pump Expands Flow Range

A new SUMP-GARD model SGK-2700 thermoplastic centrifugal pump handles flows to 1200 gpm (4500 lpm) at heads to 200 ft (60 m), it was announced by Ken Comerford, VP Sales and Marketing for Vanton Pump.

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 any immersed bearings and permits dependable operation for short or extended periods of dry run operation, with no damage to the pump.

SGK-series pumps are in wide use for effluent collection and evacuation, and for transfer and circulation of chemicals or waste resulting in minimized maintenance costs and maximized MTBR.

These rugged thermoplastic pumps weigh significantly less than pumps of equivalent capacity constructed of stainless steel, Hastelloy, Monel or other metal alloys, facilitating installation and ease of maintenance.
