名称：Vertical ball casing pump with radial impeller
介绍（Introduce）：
Vertical ball casing pump, radial impeller, single suction, one to three stages. For highest inlet pressures and temperatures. Integrated wet motor in accordance with VDE standards. The bearings are lubricated by the pumped medium, so no oil supply system is required. Designed to TRD, ASME or IBR standards.
主要应用（Main applications）：
1. Power station technology
2. Boiler cycle or primary cycle
3. Boiler cycle system
