General Instruction: This series pumps are single suction, multistage and segmnetal centrifugal pumps. The capacity of this pump ranges from 10to 66 m3/h, the head ranges from90to 1100m, the temperature of the medium should not more than 130℃. This serise pumps are mainly used for boiler feed of medium and small thermal power plant, and the other occasions which needs small flow but high head.

This series of pumps have many advanced features such as high efficiency, energy-saving. The shaft seal is soft packing gland.The materials of major parts as follows: suction casing, interstage, dischagre casing, diffuser, impeller——plain cast iron (low presssure end) and nodular cast iron (high pressure end), shaft——carbon steeel.

The meaning of pump type as following: e.g. 80DG50。80—diameter of inlet and outlet (mm); 50--single-stage head (m).
