SP and SPR submerged slurry pumps
I. Overview
SP and SPR pumps are vertical centrifugal slurry pumps, which are submerged to transport abrasive, coarse-grained and high-concentration slurry. It does not need any shaft seal and shaft seal water, and can work normally under the working condition of insufficient suction.The SP pump body is made of wear-resistant metal and the impeller is made of wear-resistant metal or rubber polyurethane material.All submerged parts of SPR pump have rubber, which is suitable for conveying corrosive slag slurry.
