The SP(R) series sump pump are vertical, centrifugal slurry pumps submerged in sump during operation. They are designed for delivering highly abrasive, large particles and high density slurries. These sump pump have no need of any shaft seal and sealing water. The pump casing of type SP pumps are made of wear-resistant metal. The wear parts are made of high chromium for the SP series and are rubber lined for the SPR series.
2.Features

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 completely equivalent with the world famous pump 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 shaft(L series) is suitable to operate in deeper level in liquid. Guide bearing is added on this pump to makes its operation more stable and flushing water should be fixed at the position of guide bearing.

The SP Type Slurry pump are designed for delivering abrasive, large particle and high-density slurries and applied over the fields such as metallurgy, mining, coal, power, building materials, and environmental protection.
