Different as they are, mine water, raw sewage, sludge cake, latex, crude oil, lime slurry, and molasses all have one thing in common: they can be pumped using NOV Monoflo progressing cavity (PC) pumps.
PC pumps are ideal for handling shear-sensitive fluids that contain abrasive materials and/or high solids content regardless of their viscosity.
PC pumps consist of a single helix shaft (rotor) that rotates within a double helix fixed housing (stator).The rotor always has one less helix than the stator, so when it rotates, it forms a continuous cavity that progresses towards the discharge end of the pump to convey process fluid out.
With a PC pump, pressure is independent of speed, which allows the pump to achieve the head required while running at a low speed for long wear life. Well-suited for both low- and high-flow applications, PC pumps can be adapted into multi-stage pumps for high pressure-handling capabilities.
