Centrifugal pumps transfer and circulate liquids using centrifugal force in a variety of industrial, commercial, and specialized applications. Straight centrifugal pumps have an intake connection in line with the impeller's eye and shaft. Self-priming centrifugal pumps use suction lift to draw liquids from a source located below the pump's inlet. Submersible centrifugal pumps transfer or recirculate liquid and work fully immersed in the liquid. Pedestal pumps transfer or continuously circulate liquids through a system. These pumps are belt or pulley-driven.
