Types of Process Pumps?
Process pumps are a broad category of pumps used in many different industries to move fluids and semi-solids from point A to point B. Applications for these pumps include moving water, chemicals, mud, or other substances.
The process pump is a centrifugal pump which is used in chemical processes, e.g. in oil refineries and the petrochemical industry (see Refinery pump). Its design is generally of the back pull-out type. Like chemical pumps, process pumps are used for handling aggressive chemical fluids.
They are also suitable for high system pressures and temperatures. If a process pump is used in the oil industry, it must generally comply with the requirements of the American Petroleum Institute (API).
- OH Types
- BB Types
- VS Types
OH – Overhung Pumps:
The impellers of these pumps overhang a radial bearing and so the support must take care of all forces, including the overhung mass and the rotor dynamic and hydraulic forces.
BB – Between Bearings Pumps:
BB pump is a “Between-bearings” pump where the impeller is mounted on a shaft with the bearings at both ends so the impeller is mounted between bearings. For all BB pumps the impeller is mounted horizontally. Type. Casing.
VS– Vertical-Suspended Pumps:
VMT pumps; these are vertically suspended pumps designed for installation in wet environments, they are used in the chemical and petrochemical sectors, at cryogenic temperatures, where vertical lifting is required and in water cooling processes.
