Lobe pumps play an important role in the petroleum and petrochemical industry and are mainly used in the following aspects:
1. **Oil Recovery**: During oil field development, lobe pumps are often used to extract crude oil from underground reservoirs. Crude oil is typically transported to surface facilities for treatment and processing.
2. **Injection of liquids**: During the production of oil wells, water, polymers or other liquids need to be injected to maintain reservoir pressure or promote the recovery of crude oil. Lobe pumps can be used to deliver these injection fluids into the well.
3. **Chemical Treatment**: During petroleum refining and processing, various chemicals are required to treat crude oil and petrochemical products. Lobe pumps can be used to deliver these chemicals, such as corrosion inhibitors, cleaners and additives.
