multistage centrifugal water injection pumps for steelworks

The multistage centrifugal water injection pump increases water pressure with each impeller stage, enabling the liquid to reach high pressures after several stages. It is widely used in water injection systems requiring high head and large flow rates, such as oilfield water injection and well washing. Additional applications include hydraulic decoking systems in oil refineries and descaling in steel mills.

Main technical parameters:

• Flow rate: 20 to 650 m³/h
• Lift: 700 to 2300 m
• Operating temperature: ≤ 105°C
• Drive power: approx. 4000 kW

Structure:

• Single-case radially split multi-stage pump: Compact structure with radial split design for better pressure resistance and stability in high-pressure environments.
• Foot mounted: Solid mounting reduces vibration and noise, ensuring stable operation.
• Suction port on the side, discharge outlet on the top: Facilitates smooth water transport and easy installation.

Main applications:

• Oilfield water injection & well washing: Maintains reservoir pressure and improves oil recovery; cleans wellbore sediments for smooth operation.
• Refinery delayed coking unit hydrodynamic decoking: Removes coke from equipment using high-pressure water, improving reliability and lifespan.
• Steel mill scale removal: Provides high-pressure water to remove scale from steel surfaces, enhancing product quality.

Features:

• Corrosion-resistant and wear-resistant design: Materials suited for high temperature, high pressure, and special media ensure long-term, stable operation.
• Advanced hydraulic parts design: Optimized fluid flow for better efficiency and lower energy consumption.
• High efficiency and energy saving: Large flow and high head performance with reduced energy use, meeting modern energy-saving requirements.
• Long life in continuous operation: Designed for continuous high-pressure, high-temperature operation with reduced maintenance and downtime.
