- Optimized labyrinth design for high efficiency and good rotordynamic behavior
- Shaft forged with low Length to Diameter (L/D) ratio for stable operation without critical speed problems and reduced vibration levels
- Radial grooves provide increased radial stiffness, reduced effect on rotor tilting, and good rotor dynamic behavior
- Swirl break at balancing piston to maintain rotor stability even when internal clearances are worn
- Optimized shaft sealing design with jacket cooling and mechanical seal: pre-warming not required
ME high pressure ring section pump
Long-life stage casing pumps for thermal power stations
Our ME pumps are specifically designed for boiler feed applications in thermal power stations. They are optimized to provide high-efficiency operation over an extended period of time, thus reducing operating and maintenance costs.
- Main boiler feed in thermal power stations
- Start-up boiler feed in thermal power stations
Main design features
- Double suction first stage available in small sizes
- Impellers are shrunk on, have keys for torque transmission, and use split ring for thrust loading
- The pumps are provided with balance drum with shrunk on thrust collar, and oil press fit to avoid damage during transient conditions
- Four-lobe journal bearing provides high stiffness and damping to minimize shaft movement
- Fully rated double-acting, tilting-pad thrust bearing
- Shrunk on coupling with oil press fit, parallel stepped or taper fit
