SP SPR Sump Slurry Pump

SP SPR Submersible Slurry Pump

SP/SPR vertical sump pumps handle coarse, abrasive high-density slurries without shaft seals or sealing water and operate steadily under poor suction conditions.

SP pump casing is made of wear-resistant metal; impellers are optional in wear-resistant metal, rubber or polyurethane.

All wetted parts of SPR are rubber-lined for corrosive slurry conveyance.
