Unique pump technology

Hydrowatt pumps use special cylinder-piston units that contain stretchable, sleeved pistons.  The head of these pistons is encased in an elastic sleeve, the open end of which is firmly attached to the cylinder, providing a hermetic seal of the pump chamber and thus a completely leak-proof pump. The piston head and sleeve are both movable lengthwise in the cylinder, the head being connected to an eccentric drive. The sleeve follows the reciprocating movement of the piston head and thus the pumping action of the pressure chamber through the elastic stretching and contracting of the piston.

Hydrowatt high-pressure pumps are positive displacement pumps with 5 or 7 plunger units, radially arranged around an eccentric drive, which are driven directly at full motor speed (e.g. 50 Hz – 1’500 rpm).
