The hard coupling of Vanton’s Sump-Gard drive shaft to the motor shaft reduces height above the mounting plate by approximately 50%. This allows the pump to fit in restricted areas commonly encountered in replacement and OEM applications, while lowering the centre of gravity. The cantilevered, large diameter shaft eliminates the need for immersed bearings prone to fail in caustic, acidic and abrasive applications, and allows run-dry operation with no damage to the pump.
All wetted components, including a heavy wall shaft sleeve, are molded of solid Polypropylene, PVDF or CPVC, eliminating corrosion associated with pumps constructed of stainless steel and high alloys, as well as delamination and wicking related to plastic-lined and fibreglass pumps. Since all wetted surfaces are chemically inert, the pump is also rated for handling of reagent grade chemicals, high purity water and other fluids that must remain free of contamination.
Available in lengths to1.2 m with motors to 37 kW, the pump handles flows to 3,028 lpm and heads to 55 m at temperatures to 135°C. Impellers are offered in closed and semi-open configurations, as well as recessed for pumping of slurries containing solids or stringy materials.
