Water pump DDHF/Ms

hydraulic motorimpellerrefinery

Proven multi-stage, diffuser barrel design that delivers high reliability, efficiency and flexibility in demanding onshore and offshore water injection applications. Featuring low vibration, optimized hydraulic design and easy maintenance. DDHF/Ms have been designed to fit the requirements for onshore and offshore water injection applications. The design is an improvement of that previously referenced as DDM and includes some features of a pump designed and tested by Nuovo Pignone for water injection in direct connection with a gas turbine running at 10000 rpm. The other services that can employ DDHF/Ms are: boiler feedwater, pipeline, amine, energy recovery and CO2 injection. One of the main requirement for the pumps selected for high pressure water injection is the reliability and many design features have been introduced to address this essential need. BHGE Nuovo Pignone, during the selection process, can perform the optimization of the complete system conforming to the objectives of the specific customer for example in terms of CAPEX, OPEX and operability. One of the main accessories that need to be selected are the booster pumps. The selection of both main and booster pumps is performed jointly to obtain the best combination. Evolved from our proven DDM diffuser design and DDHF impeller families, DDHM pumps provide ultra reliability in the most demanding onshore and offshore water-injection applications — designed and fully tested for direct connection with a gas turbine running at 10,000 rpm. They are also very well suited for boiler feed water, oil gathering, amine charge, and CO2 injection.
