It is a suitable corollary equipment for the steam turbogenerators to pump over the condensed water out of the condenser in metallurgical plants, power plants, refineries, chemical and petrochemical plants, low-temperature projects and pump over the liquid from the high-vacuum containers. It is mainly used for the occasions where the cavitation demands high in the process flow in power plants, metallurgical plants, refineries, petrochemical plants, low-temperature projects, pipelines and offshore industries and it can be used in else place where the agent is similar to the condensate water. 2、Operation range The temperature of delivered liquid is below 80 ℃(The temperature can be below 150 ℃ if a cooling device is fixed in cooling chamber). The head is from 22 meters to 320 meters. The 3 3 capacity is from 2m /h to 250 m /h. 3 、Type instructions For example ：GN3/12、3N6×2 and 4N6A Mean:3Suction pipe diameter （inch ） NCondensate pump G
