Vertical Pumps / R33 / R38 Rubber Material For Mine Dewatering
Introduction:
SME SP and SPR vertical sump pumps are a type of special vertical slurry pumps used for industrial sectors like mining, mineral processing, quarries etc., and they are different from submersible sewage electric pumps.
SP series centrifugal slurry pumps are cantilevered, vertical, centrifugalslurry pumps.
Features :
1. SP (R) type submerged pumps are vertical centrifugal slurry pump, generally into the pool or pit to
work,used to transport abrasive, coarse particle, high concentration slurry.
2. Don't need any shaft seal and shaft seal water, in the inhaled volume insufficient conditions they
can also work normally.
3. SP (R) type submerged pumps' pump body is made of wear-resisting metal. Impeller is made of
wear-resistant metal or rubber, polyurethane SP (R) type submerged pumps parts into the liquid with
rubber lining,they are all applicable to transport corrosive slurry.
