Immersion Pumps are plain centrifugal pumps with the impeller fitted on the driving shaft extension. They are mounted on top of the container, the pump extension being immersed in the coolant. The maximum coolant level must stay a few mm/inches below the mounting flange. The STA series offers a (SAE) flange with pressure gauge connection port. The flange can be rotated for either horizontal or vertical pipe connections. All types are also available as quick-suctioning immersion pumps equipped with “BRINKMANN’s Suction De-aeration System”. See series SAL. All types are also available as suction immersion pump with a connection to the vacuum filters on the suction side. See series STS.
