Performance-designed to ensure high reliability and efficiency
Benefits
Lower operating costs as a result of high efficiency and energy savings
Centerline mounting feet increase thermal-expansion tolerance
Hard coating on all mating surfaces of stage seals and balancing drum to increase life
Features
Clearances and tolerances between rotor and stator parts enable frequent starts and stops with rub-free operation
Diffusers and return channels are precision-casted and machine-finished for high conformity and low radial loads on the rotor
Double, symmetrical balancing flow lines minimize axial thrust variation and eliminate asymmetries that cause vibration
Applications
Boiler feed in power generation plants
Reverse osmosis
Energy recovery, CO₂ injection
Our DDHF-R multistage centrifugal pumps are designed for the requirements of several services including boiler feed in power generation plants, pipeline, reverse osmosis, energy recovery, and CO2 injection.
This pump family is designed to work in a demanding environment, delivering pressure as high as 350 barg, withstanding process temperatures up to 250°C, and managing flows close to 1,000 m3/h with an extremely high level of reliability and efficiency (over 85%). Based on the above, a single train's installed shaft power can approach 10 MW in a high-speed arrangement.
Optimized performance
To maintain such high performance with a short warm-up time, this product uses innovative materials—mixing alloyed steel and composites—and a unique layout with thermal guides and baseplate specifications tailored to customer requirements.
