Andritz Company offers a variety of centrifugal pumps specifically designed for the oil and gas industries. These pumps are engineered to meet the demanding requirements of this sector, ensuring efficiency and reliability. The main types of centrifugal pumps related to the oil and gas industries include:
1. End-Suction Pumps: These are commonly used for transporting crude oil and other liquids. They are designed for easy maintenance and high efficiency.
2. Split Case Pumps: Known for their durability and high flow capacity, split case pumps are ideal for applications requiring large volumes of liquid, such as in refinery processes.
3. High-Pressure Pumps: These pumps are designed to handle high-pressure applications, making them suitable for transporting fluids in various stages of oil and gas extraction and processing.
4. Multi-Stage Pumps: These pumps are used when high pressure is required. They consist of multiple impellers, allowing them to achieve higher pressures than single-stage pumps.
5. Specialized Pumps: Andritz also develops customized centrifugal pumps tailored to specific applications within the oil and gas sector, including pumps for handling corrosive or viscous fluids.
Single-stage centrifugal pumps
ANDRITZ single-stage centrifugal pumps from the ACP are available in a highly wear-resistant, open impeller design. Thanks to their low axial thrust and open channels, these pumps are suitable for conveying many different media. Depending on the impeller design, they can convey slightly contaminated and contaminated media with some solids and content with consistencies of up to 8%. Equipped with our innovative SMARTSEP degassing system an additional separation impeller acts as an integrated degassing system and removes gas from the media and conveys fibers reliably back to the pump at the same time. Thus, no additional vacuum pump is needed. The controlling of the degassing valve becomes very easy. When the pump is running the valve is open, but when the pump is not running the valve is closed.
