The SPX100D hose pump is designed for sludge applications.
The SPX100D from Watson-Marlow uses no valves, seals or rotors in the product stream, and can run dry and handle high grit or air entrained sludge. The pump has flows up to 400 gpm which enable it to pump scum, thickener underflow, belt press or centrifuge feed. The pump can also transfer corrosives, abrasives, shear sensitive fluids, high viscosity fluids, high density fluids, large solids and long stringy materials.
Peristaltic hose pumps are virtually maintenance free and both pump rotors are supported by their own high strength bearings. Unlike other pump types, the highly abrasive materials do not affect pump life. Materials are fully contained within the hose element and don’t come in contact with the moving parts of the pump, preventing abrasive wear.
The pumps’ discharge pressure reaches up to 232 psi and operating speeds reach up to 30 rpm for continuous use and up to 38 rpm for intermittent use. Every Watson-Marlow peristaltic pump is an inherent metering pump with repeatability at 99.5%.
