Both investment costs and lifecycle costs are taken into consideration when designing the optimal pump. An optimized hydraulic design guarantees maximum efficiency. M-series high-pressure stage casing pumps have a modular design. This allows Sulzer to find the most efficient solution to meet customer requirements, typically for feedwater pumps and start-up feedwater pumps for gas-fired combined-cycle power plants, among other applications.
Modular hydraulics for high efficiency in a wide range of operating conditions as required for gas-fired combined-cycle power plants
Optimized design for thermal conditions as applicable in gas-fired combined-cycle power plants
Centerline mounted with large branch sizes for optimized inlet flow, low noise level, and higher allowable forces and moments
Unaffected by rapid temperature variations and therewith highly suitable for gas-fired combined-cycle power plants where frequent start-stop operation is specified
Stiff shaft design for critical speeds above the maximum operating speed
Multiple screws mechanical tensioners are used on large sizes to allow simpler tightening and loosening
The MD pumps are suitable for pumping clean or slightly polluted, hot or cold water. They have been specifically designed for application such as:
Main boiler feedwater pump in captive, independent, biomass, and industrial power plants
Main feedwater pump in gas-fired combined-cycle and concentrated solar power plants
Start-up boiler feedwater pump in utility thermal power plants
High-pressure water pump in general industry
