1. Series SP(R) pumps are vertical and centrifugal slurry pumps, which work submerged to transport the abrasive and high-density slurry with large particles. The pumps have no need for any shaft seal and sealing water. They can also run under the conditions of inadequate suction duty.
Wet parts of SP(R) pump are made of wear-resistant metal.

2. All parts of SP(R)pump immersed in liquid are equipped with rubber liner, which is suitable for delivering the non-edge abrasive slurry.
Sump pump with extended-length shaft (L Series) is suitable to operate in deeper level in liquid. Guide bearing is added on this pump to make its operation more stable and flushing water should be fixed at the position of guide bearing.
