The NOV Mono Munchpumps, which each consist of a Compact C Range progressing cavity (PC) pump and CB201 Muncher, were installed to replace the plant’s existing centrifugal pumps which would, over time, cause a reduction in flow or block up completely.

NOV Mono’s Compact C progressing cavity pump range has been designed to fit into compact spaces. The pump uses positive displacement for process control, variable speed for accurate dosing and features a suction lift capability of over 8 m.
 

The CB201 Muncher model from NOV Mono has been specifically designed to meet above ground pump station requirements for delivering a 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 is fitted with a series of interleaving cutters that allow liquid to pass through, trapping and macerating solids with their high torque cutting action.
NOV Mono Munchpump packages consist of either a SB or TR Muncher, with a NOV Mono progressing cavity pump, for sewage and sludge maceration and pumping. The twin shaft, low speed, high torque grinder offers as much as 50% lower energy consumption than a comparable submersible or centrifugal wet or dry well pump system.
