API 610 Centrifugal Pumps
API 610 is a specification developed by the American Petroleum Institute (API) for centrifugal pumps used in the oil and gas industry. It covers the design, materials, performance, and testing requirements for centrifugal pumps, including overhung and between-bearing pumps, in process services, as well as centrifugal pumps used in petroleum refineries and petrochemical plants. API 610 provides guidelines for ensuring that centrifugal pumps are reliable, efficient, and safe for use in these demanding applications. The specification covers a wide range of topics, including pump components, materials, vibration, shaft sealing, and performance testing. Adherence to API 610 is important for ensuring that centrifugal pumps used in the oil and gas industry meet industry standards for quality and performance.

API 610 defines two types of centrifugal pumps: Overhung pumps and between-bearing pumps.
Overhung pumps: In an overhung pump, the shaft extends from the impeller on one side of the pump, with bearings on the same side as the impeller. This design allows for a more compact and simpler pump, but also increases the load on the bearings.
Between-bearing pumps: In a between-bearing pump, the shaft extends through the center of the pump and is supported by bearings on both sides of the impeller. This design provides better balance and stability but is typically larger and more complex.
Both types of pumps can be used in various applications, and the choice between the two will depend on the specific requirements, such as flow rate, head, and fluid properties. The API 610 specification provides guidelines for the design and performance of both overhung and between-bearing pumps.
