A design enhancement from the popular dewatering submersible elevates this pump into a class of its own.
This pump is 100% manufactured in-house by our team of specialised technicians and engineered to meet the demanding application in underground deep mining.
Ask us for our references and we will be happy to share with you how mining managers have saved capital and operating costs by switching to PRZ.
100% Made in South Africa
110kW
Available in 150mm and 200mm discharge sizes. These pumps can achieve 13 bar pressure at 290 l/s with best efficiency 78%. They are designed to withstand working pressure of 50bar and are statically tested at 75bar and are therefore safe and efficient in series pump configurations. Larger vein sizes decrease probability of clogging.

Advantages over submersibles or self-priming pumps:
1) Vertical spindle pumps on floating barges require minimum maintenance and maximize intervals between maintenance on account of they being powered electrically and not diesel driven in the case of self-priming pumps and due to the robust design of the vertical spindle pumps with cantilever shafts and oversized bearings and no mechanical seal requirement. Resulting in opex savings.
2) The pumps spindle depth (NPSHA) remains constant as the pit water level rises and falls in flash flooding occurrences. No need to prime the pumps.
3) Pumps continue to operate even in flash flooding scenarios translating into a safer work environment because crews are not required to move pumps to higher ground.
4) As much as 30% more cost effective from a capital expenditure point of view.
5) Simple run dry water seal arrangement, eliminating expensive mechanical seals.
6) Eliminating the replacement costs and maintenance expenses of a diesel engine.
9) Cost saving by eliminating diesel refueling in the pit.
10) Diesel Refueling in the pit in flash flooding conditions could contribute to a safety hazard.
