SCAM pumps work as a hydraulic turbine with partial
injection operated by an electric motor.
The water arriving axially into the water inlet body
enters radially the impeller, passing through an element
with a rectangular section called distributor.
The drain takes place when the impeller blades run in
front of the distributor.
Thus, slightly concave and few millimetres thick water
blades are formed.
The incondensable substances and the saturating steam
to suck are trapped among the water blades and are led
to the drain, where they are expelled by a deaeration
system - shown in the general arrangement - consisting
of a convergent diffuser where the fluid re-compression
