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 dimensions are based on standard specification EN 12157.
The maximum coolant level must stay a few mm/inches below the mounting flange.
The delivery capacities shown in the tables apply to water at 1 mm2/s (1 cSt) and 20° C.
For the delivery of oils, the values will decrease do to higher viscosities which result in an increased pipe resistance.
