Compact High Flow Pump for Sludge

April 26, 2010
The hose pump can be used for challenging sludge applications, using no valves, seals or rotors in the product stream, the unit can run dry and handle high grit or air entrained sludge with ease. With flows up to 400 gpm, the pump is ideal for scum, thickener underflow, belt press or centrifuge feed, according to the manufacturer. With a self-loading design, hose replacement is quickly achieved where the pump sits. There is no drive realignment or off-site rebuilding of the pump required, significantly reducing maintenance cost. Advanced hose technology enables the unit to pump corrosives, abrasives, shear sensitive fluids, high viscosity fluids, high-density fluids, large solids and long stringy materials. Peristaltic hose pumps are virtually maintenance free with no expensive seals to replace, no check valves to clog, and no rotors and stators to wear out. Both pump rotors are always fully and centrally supported by their own high strength bearings. 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 pump also provides easy access to shims and shoes, and the shaft design ensures fail-safe operations. 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.
