Features of Positive Cavity Screw Pumps for Sewage Sludge and Polymer

  •  Wide application, it can be used for conveying of flowing materials, even non-flowing materials

  • Continuous conveying, small pulsating quantity

  • The media is not stirred in the pump and is free from squeezing and cutting

  • The flow is in direct proportion to the rotating speed, variable output, measurement feeding

  • Elastic stator, certain abrasion resistance


Conveying Medium of Positive Cavity Screw Pumps for Sewage Sludge and Polymer

  • Various viscous media (the highest viscosity reaches 106 mm2/s)

  • Fluids with various concentrations and dewatered and dried materials

  • The media containing solid particles, fibers and suspended solids


Horizontal Direct Linking of Positive Cavity Screw Pumps for Sewage Sludge and Polymer

  • Features: It is directly driven by gear motor, compact structure, short length of the pump

  • Parameters: 600m³/h; maximum pressure: 2.4MPa or higher




  • Are your pumps protected against dry running?

    No, unprotected centrifugal pumps are not generally designed for dry running. It is important to give us or your dealer as much information as possible about the system in which the pump is used. Inlet pressure, the type of liquid to be pumped, together with relative density, viscosity and temperature, for example, are required in order to allow CNBM to recommend the right pump with the right gaskets for a long operating lifetime.

  • How can I get trained on CNBM products?

    Yes, we provide training courses in our factory (products, general and specific pump technology, hydraulics, and practical applications). Please consult your sales manager or get in touch with our headquarters for more information.
