名称：Horizontal, transversely split ring-section pump with radial impeller
介绍（Introduce）：
Horizontal, transversely split ring-type pumps with radial impellers, single-suction or double-suction, multi-stage.
主要应用（Main applications）：
1. Feed water transport for power plants
2. Boiler feed water
3. Condensate transport
4. Pressure water generation in pressure equipment, debarking equipment, descaling equipment and snowmaking equipment

优势（Advantages）：
1. High operational reliability due to balancing of axial thrusts by balancing discs and adjustment of the pump housing to the curvature of the rotor
2. One or more branch flows from the feed water for other uses in the power station
3. Easy maintenance due to easily accessible wearing parts (bearings, seals, balancing elements) and metal housing seals ("metal to metal")
4. Optimized inlet flow, avoidance of cavitation wear in the pump, long service life
5. Reduced energy costs, as no preheating of the pump is required and more than 100 impeller/steering wheel combinations can be combined for optimum efficiency
6. Lower investment costs due to optional double suction (no backing pump required in many applications)
