BB5 DDHF

Aug 01, 2023

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.

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. The package also includes customization options to best suit each customer's unique project requirements.

To reduce carbon footprint, our DDHF product line includes a compact machinery layout option for high-density CO2 pumping. An extensive research campaign was performed with International Labs to characterize many CO2/hydrocarbon mixtures, and design the hydraulics to best fit the fluid evolution. The pump's performance has been extensively validated with rigorous multi-speed testing at our factory.

We can provide full onsite support during installation and commissioning to guarantee flawless execution and quick response.

After installation, we can support continuous improvement throughout the pump's operating life with conversion, modifications and upgrades, including:

A remote monitoring and diagnostic service is also available.
