Mono Pumps

Viewing: Widethroat Range

Mono Widethroat W Range

The NOV Mono progressing cavity Widethroat W range has been designed handle highly viscous materials, such as sludges, slurries, thick non-flowing pastes and de-watered sludge cake with viscosities up to 1,000,000cP.

This transfer pump consists of an enlarged rectangular inlet with a screw conveyor to assist the product into the pumping element. Options are available to modify the inlet with either large diameter augers, integral bridge breakers or both.



  • Provides a process efficient method of handling sludges with high solids content
  • Different design configurations to suit the application, dry solids approaching 40% can be handled when fitted with integral bridge breakers or large augers
  • Facilitates ease of maintenance through the simple design and use of a plug in shaft
  • Designed to run at relatively slow speeds to minimise damage to shear sensitive products
  • Pumps are available as monobloc or bareshaft
  • Can be supplied with a Muncher, horizontally mounted onto the hopper, to assist solids reduction prior to pumping
  • Pumps can be supplied to comply with the ATEX Directive 94/9/EC
