Boiler feed pump (BFP) for biomass wasteBoiler feed pumps for biomass firing power plants applications are typically small/medium ring section type. Axially split multistage pumps are also available when required. The pump size and the design pressure will depend very much of type and the output of the power plant.
Brine re-injection pumpThe brine re-injection pump re-injects the low enthalpy reject brine back to the geothermal field to renew the available resources.
Chemical recoverySulzer’s extensive product portfolio is designed to meet the most demanding hydraulic coverage requirements in your evaporation, recovery boiler, and white liquor preparation processes.
Feed water pumps for solar power generationFeed water pumps (FWP) pump feed water from the de-aerator through the HP heaters to the solar steam generator. The major characteristic of FWP is their high differential head. The FWP are usually horizontal ring section type, but depending on customer requirements, they can also be barrel or axially split type.

RO-island HPPThis is the heart of the SWRO Desalination process, where the desalination effect takes place. The Treated sea water is fed by means of the High Pressure pumps into the RO membranes, obtaining permeate or product water and high pressure brine rejection, whose high pressure energy is recovered by selected Energy Recovery Device.
RO-Island HPP 2nd passThis is the heart of the SWRO desalination process, where the desalination effect takes place. The treated sea water is fed by means of the high pressure pumps into the RO membranes, obtaining permeate or product water and high pressure brine rejection, whose high pressure energy is recovered by selected Energy Recovery Device.
Water supplyMeeting today’s challenges and high requirements within water intake, sedimentation, sludge treatment, fine screening, and water distribution processes.
Water transportationWater transport pumps are pumping large volumes of water over mostly long distances and high geodetic heights to geographical areas or industries where it is required for different purposes. We offer various configurations according to your needs.
MC high pressure stage casing pumpM-series pumps have a modular design thus allowing Sulzer to find the most efficient solution to meet customer requirements.
MD high-pressure stage casing pumpBoth investment costs and lifecycle costs are taken into consideration when designing the optimum possible pump as an optimized hydraulic design guarantees maximum efficiency.
