- Robust design to accept high piping loads
- Single cover design to reduce overhaul times
- Radial split design does not require pre-warming
- Split bearing housings allow for bearing inspection without pump disassembly
- Single mechanical seal provides higher efficiency
HPTd single stage double suction pump
A neat design for nuclear / single stage double suction pumps stand the test of time
The HPTd pumps are optimized to provide high-efficiency operation over an extended period of time, thus reducing operating and maintenance costs. Their robust construction and tolerance of changing conditions makes them particularly suitable for cyclic operation.
Main feed water in nuclear power stations
Main design features
- Cast casing construction
- HPTd impeller has low specific speeds to ensure a stable head curve and a wide operating range
- Impeller with staggered vanes for low pressure pulsation
- Both diffuser and double volute designs are available to minimize radial thrust and pressure pulsations
- Multi-lobed high damping radial bearings for rotor dynamic stability. Double acting high-capacity tilting pad axial thrust bearing.
