This series of pumps are single-stage, single-suction, cantilever and horizontal structure, and are single-pump casing pumps. According to the drive mode, they can be divided into two typical structures: the frame-mounted type and the integrated pump-reducer housing type. Lubrication can be achieved by grease lubrication or oil lubrication. They are mainly used for continuous conveying of highly abrasive materials with particles too large to be handled by ordinary slurry pumps. Among them, the DGH type is a high-head gravel pump.

The wetted parts of this pump are made of wear-resistant materials such as hard nickel and high-chromium alloy. The discharge direction of the pump can be adjusted to any position within 360°, offering advantages such as easy installation and operation, good cavitation resistance, and high wear and corrosion resistance. The pump rotates clockwise when viewed from the drive end.
