Two shoes mounted at 180° on a rotating wheel compress successively a reinforced rubber hose that contains a fluid to be pumped.

The compression of the hose by the rotating shoes creates continuous suction at the inlet of the pump and pushes the fluid to the outlet of the pump.

The pump casing contains a lubricant that reduces friction and insures the best pump performance with a minimum of maintenance.

The pumped liquid is in contact with only the interior of the rubber hose, thus permitting the pumping of a wide variety of reactive fluids.
