Type D Multistage Clear Water Pump
The D-type multistage clear water pump is a multi-stage, sectional centrifugal clear water pump suitable for use in mining, industrial plants, and urban water supply and drainage systems. It is designed to convey clean water free of solid particles, abrasives, or suspended solids—specifically, liquids with physical and chemical properties similar to pure water. The temperature of the liquid being pumped can range from -20°C to 80°C, and the pump can handle inlet pressures up to 0.6 MPa. Typically, the pump body is made of cast iron due to the stable chemical nature of the clear water being transported, which results in minimal corrosivity. However, vertical multistage clear water pumps are also available in stamped stainless steel versions, allowing customization based on customer requirements. From a cost-performance perspective, horizontal clear water pumps commonly feature cast-iron construction.
