What is a Process Pump?

Process Pumps are used to move fluid in an industrial process. Process Pumps can be any variety of pump types depending on the application. They can be either heavy-duty centrifugal pumps used to pump corrosive or abrasive fluids. Or, they can also be positive displacement pumps.

Two of the most common types of process pumps:

1- API Process Pumps are centrifugal pumps used in hydrocarbon processing plants and refineries. The pumps are designed to the API 610 standard, which covers a number of centrifugal pump types, including: vertical turbine pumps, end suction pumps, multi-stage pumps, horizontal split case pumps, and others.

2- ANSI Process Pumps are considered end suction centrifugal pumps. ANSI process pumps are designed to meet the ANSI B73.1 standard. This type of process pump comes in a wide range of materials depending on the application. ANSI process pumps are used in the chemical industry, paper mills, refineries and other plant environments.

Summarized of API 610 standard:

The different API 610 centrifugal pumps are based on the API 610 standard. Pumps are classified into three main categories: OH, BB and VS, with subcategories based on various factors such as coupling used, number of stages, and casing. Detailed discussions on the OH, BB, and VS types of pumps, including their design, installation, and operation. The importance of understanding the principles and differences between these types of pumps is emphasized to ensure proper installation and efficient operation. Some other types of centrifugal pumps, such as Multi Stage, Single Stage, and VS series pumps, are also briefly compared and contrasted in this section.

Summarized of API 685 standard:

The API 685 standard establishes strict design and construction requirements to ensure the safety and efficiency of pumps in critical applications. This involves considerations such as structural strength, precise alignment of components, tightness and responsiveness to varying operating conditions
