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.

Features and Benefits:

• Continuous flow eliminates pipework-damaging pulsations
• Continuous seal line between rotor and stator eliminates product backflow and slip
• Variety of construction materials for adaptability to nearly any operating condition
• Low running speeds for long wear life
• Rolling action of rotor releases trapped solids quickly, reducing abrasive wear
• Long-haul pumping eliminates the need for a series of pumps
• Suction lift up to 28’ allows deep sumps to be emptied without submersible equipment
• Gentle pumping action keeps delicate solids intact, minimizing shear, crush damage, and solid degradation
• Continuous cavities handle suspended solids with ease
• Constant discharge capacity for a given speed, rotation, and pressure for accurate metering and dosing
• Reduced wear extends periods between routine maintenance
• Positive displacement for a uniform flow
• Dual directional capability allows one pump to meet all operational needs
• Ability to turn suction chamber 90° for easy installation
