Hanson Cement has invested in a duty/standby Mono Munchpump package for the sewage handling facility at its plant in North Wales, UK.

The plant had originally been using submersible pumps for sewage transfer duties, but these had become inefficient.
 
“Any maintenance work involved an engineer going down into a confined space. We wanted to make maintenance and cleaning operations safer, easier and more effective,” said Hanson engineering manager Paul Cowell.
 
The above-ground Munchpump package includes two EZstrip progressing cavity pumps and two SB Munchers transferring the sewage at 25m3/h to the main sewerage system. The Munchers macerate any solids within the flow to a small particle size, preventing blockages. 
 
As a result, Mono says small bore pipework, typically 50mm, can be used while it claims
Munchpumps can consume less than 50% of the energy of a comparable submersible pump.
