Centrifugal pump BB5 DDHF

CO2ammoniafor gas

For API 610 heavy-duty services, fully compliant with the most stringent NOC and IOC specifications Benefits High efficiency and reliability with simplified maintenance Pull-through design available on request Features Internal volute casing and a back-to-back impeller configuration Low net positive suction head Reverse hydraulics available to operate as hydraulic power-recovery turbine Applications Refinery and petrochemical: reactor feed in hydrocracking, ammonia charge processes, carbamate Enhanced oil recovery injection: treated seawater, seawater, CO₂ injection, oil flow line Gas treatment: amine services for gas sweetening Our DDHF multi-stage, double-casing, centrifugal barrel pumps are engineered for reliable 20-year operation, well proven with over 1,000 units installed worldwide. They’re highly efficient with an optimized hydraulic design that provides low net positive suction head (NPSH)—close to the maximum theoretical threshold. Proven performance, upstream and downstream DDHF pumps incorporate proven solutions to common materials, pressure, flow rate, installation, and integration challenges faced in upstream oil and gas applications. They also deliver exceptional performance in heavy-duty refinery and petrochemical applications—easily handling fluids with low specific gravity, pressures reaching 670 bar, and temperatures up to 450°C. Key design features include an internal volute casing and a back-to-back impeller configuration, which simplifies maintenance, reduces downtime, and guarantees high reliability.
