Materials of Construction and Why This Matters for Submersible Pumps

The abrasiveness of the slurry or the suspended solids will affect the choice of construction materials used for the pump’s wear parts. Most mining and construction applications will demand that the pump is made of durable materials such as cast iron or Hard-iron™.

In many applications, the chemical content of the water, sludge or slurry can also be corrosive. This requires that the pump or certain of its components be made of corrosion-resistant material. Grindex dewatering and sludge pumps can be supplied in stainless steel , while it can supply pumps with a blue gel coating on the wear parts. Zinc anodes are another option to resist corrosion, and these can be applied across the range.
