Two undersized cutter pumps swapped for a single DAB grinder
This pit had two undersized 0.75kW cutter pumps working a pressurised main — more than they were ever built to shift — run through a dual-pump controller packed with contactors and switchgear that had become the weak point of the whole system. We simplified the lot: out came both cutter pumps and all the control gear they leaned on, and in went a single DAB FEKA VS grinder sized for the duty, with the old controls and contactors bypassed. Fewer parts to fail, and a pump that can actually move what's put through it.
