1 - Motor type kinematic motion with crankshaft connecting rods-bearing-pistons system.
2 - Thermal treatment on connecting rod rings provide wear resistance and long life operation.
3 - Piston sleeves in cast iron and pre-set piston delivering high volumetric efficiencies
4 - Oversized ball bearings on the pump shaft for longer life.
5 - Double body head in polypropylene incorporating a die-cast aluminum core.
6 - Separate and replaceable suction and pressure circuits.
