Two Munchpump packaged pumping systems from NOV Mono have been specified by United Utilities to improve efficiency at its wastewater-treatment works in Caldbeck by preventing pump blockages and minimising down time at the site.

NOV Mono’s Compact C progressing cavity pump range has been designed to fit into compact spaces while reliably performing to the maximum duty requirement of the application.

The pump uses positive displacement for process control and variable speed for accurate dosing, and features a suction lift capability of more than 8m.

The CB201 Muncher model has been designed to meet above-ground pump-station requirements for delivering conditioned wastewater through small-bore pipework into a receiving wastewater-treatment package.

The SB Muncher is a twin-shaft, low-speed high-torque grinder, each shaft being fitted with a series of interleaving cutters that allow liquid to pass through, trapping and macerating solids and reducing energy consumption by as much as 50 per cent compared with a comparable submersible or centrifugal wet or dry-well pump system, NOV Mono claims.

Key benefits of product application

  • Pump capacity can be limited to offer a controlled feed
  • Improved effluent BOD (Biological Oxygen Demand) loading into a small treatment plant
  • Very low pump speeds can be selected to reduce abrasive wear
  • Efficient maceration of sewage eliminates the need to screen inflow and the associated labour costs for handling and disposal of screenings
  • Low operating and cutter-tip speeds reduce mechanical wear
  • Reduced noise levels when compared with high-speed macerators
