GE Oil & Gas High-pressure diffuser barrel multistage pump DDHM API610 / ISO13709 type BB5 for high reliability and efficiency onshore and offshore
A proven package Reliable Flexible Our DDHM pumps are designed for ultrareliability in the most demanding onshore and offshore water-injection applications. They are also well suited for boiler feedwater, pipeline, amine, energy recovery and CO2 injection. During the selection process, we can tailor the complete system to specific customer objectives in terms of CAPEX, OPEX and operability. This service includes matching of the main and booster pump as a crucial step in optimizing performance.
Improved design for water injection High-pressure diffuser barrel multistage pump DDHM Design features 5 6 3 1. Centerline mounting of barrel to increase tolerance to thermal expansion 2. Inlet channel shaped to optimize flow uniformity and reduce net positive suction head (NPSH) required 3. Lifting lugs and many other design features to facilitate assembly and handling of components 4. Impellers with double keys and shrink-fit by induction heating to minimize residual unbalance 5.
Other key features Operating data Differential head up to 2,500 m Flow rate up to 1,500 m3/h Shaft power up to 10 MW Rotational speed up to 6,600 rpm Head rise 15 – 30% Operating temperature -10°C – 120°C Impeller diameters 250 – 385 mm The standard frames are: 4x11, 6x11, 6x12, 8x15, 10x16. Continuously bladed diffuser-return channel maximizes range of flow with high efficiency. Diffusers are precision casted to guarantee high conformity and low radial loads on the rotor.
