Abstract (en)
[origin: EP2902631A1] An adjustable centrifugal pump (10) comprising a flanged body (11) connectable to a volute with an appendage (14) suitable to house an actuator device, a crankshaft, an impeller (32), a cup-shaped shutter (50) suitable to slide axially and position itself on the outer perimeter of the impeller (32); with a rotor (40), rotatably and concentrically housed externally to said shutter (50), having inclined surfaces (42) acting in conjunction with further inclined surfaces (52) of the shutter (50), so that a rotation of said rotor (40), corresponds to a translation of said shutter (50).
