The wet pump parts of impeller, front liner, rear liner is made of special high chrome alloy, with the hardness not less than 58HRC, while the pump casing material selection, takes into account the pressure requirements, to use of wear-resistant cast steel, with a hardness about 48HRC. And also depending on the different dredging application, we use different material to meet the requirements of the customer.
