Pump & Valve were asked to quote on 2 x pumps for pumping GBT thickened sludge at a large treatment plant in the South Island. GBT thickened sludge is not an easy liquid to pump furthermore the pumps needed to be reliable and offer long service life.
CASE STUDIES
Coal Mine Fines Pumping
Pump & Valve were called in to look at some end suction dry mounted pumps that were pumping water containing high levels of coal fines out of a dam and into a treatment plant. The existing pumps had priming and wear issues – and typical life was only 6 months. The duty required was 175l/sec @ 45m head.
Pumping waste from an abattoir
A large abattoir need a pump for pumping waste out of a breaker and into some bins. The ‘waste’ consisted of lumps of fat, skin, intestines, the odd hoof and whatever else could find its way into the drain! One of the challenges was that the flow was inconsistent and the media would range from being very watery to being very thick.
