Rotating impeller inside a casing decreases the pump’s inlet pressure making fluid flow into the pump. Exiting fluid has high pressure and velocity due to centrifugal force of impeller. Centrifugal pumps are used in petroleum, petrochemical and gas industry process services (API610), Power Plants; Water resources, Fire Fighting (NFPA20) and etc.
Rotary pumps are positive displacement pumps consisting of one or more rotating impellers expanding and collapsing cavity at the casing inlet and outlet, respectively. These pumps are best option for pumping viscose or multiphase fluids for the oil and gas industry (API676), as well as the industrial, food and pharmaceutical sectors.
