OurDDHF multi-stage, double-casing, centrifugal barrel pumps经过精心设计，可用于可靠的20年运营，已验证全球安装了1000多个单元。它们具有优化的液压设计高效，可提供低净正吸头（NPSH），即最大的理论阈值。
Specification
Proven performance, upstream and downstream
DDHF泵纳入了上游石油和天然气应用中面临的常见材料，压力，流量，安装以及集成挑战的良好解决方案。他们还提供了重型炼油厂和石化应用中的出色性能 - 既处理具有低比重力的流体，压力达到670 bar，温度高达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.
CO2applications
To reduce carbon footprint, our DDHF product line includes a compact machinery layout option for high-density CO2pumping. 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.
Full lifecycle support
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:
- Impeller modification or diffuser replacement to match actual operating conditions
- Wear-ring upgrade to composite materials that reduce internal leakage, and increase efficiency with clean fluids
- Super finishing of internal wetted surfaces to increase efficiency
A remote monitoring and diagnostic service is also available.
