Parker/Gresen General Introduction When Parker Hannifin acquired Gresen, it was an opportunity for product extension and cross selling. Gresen was a manufacturer of a wide range of hydraulic pumps, motors, cylinders, control valves, filter
and electronic controls for on and off highway vehicles. Gresen is a strategic complement to Parker’s existing hydraulics business, adding a variety of mobile products which will offer customers the convenience and value of total system capabilities for their motion
and control applications, all from one source.
