Abstract (en)

A pneumatically-operated cooling pump (10), especially suitable for conveying and circulating coolants in internal combustion engines, comprising a containment body (12) positioned above an underlying volute inside which is placed a shutter which surrounds an impeller keyed on a rotation shaft, immersed in a fluid of water and glycol and suitable for setting in motion said fluid, the pump comprising pneumatically-operated mechanical means with axial movement to operate the shutter defined by an actuator unit comprising a ring (42) and at least three rods (44) sliding axially with respect to the containment body (12) and static seal means defined by shaped diaphragms (52), stabilized to the rods (44) and to the containment body (12), positioned to separate between the containment body (12) and the underlying coolant and cooperating with the actuator unit for the movement of the shutter.
