About Denison

Denison Hydraulics is now a division of Parker Hannifin HPD

Gold Cup Series Pumps

Denison Gold Cup Series pumps are piston pumps for open and closed closed circuits. The closed hydraulic circuit variable pumps are comvined with a fixed motor for a constant torque output at a fixed maximum pressure over the full speed range. Speed and direction are controlled with a variable displacement over-center pump. Power from overhauling loads is regenerated back into the pump prime mover. Motor speed is limited to the maximum speed permitted by full pump displacement. System is capable of full power only at maximum pump displacement. The open circuit pumps include a cross-center variable displacement pump which is normally limited to one side of center. The auxiliary pump supplies only servo pressure to control the main pump displacement and inlet porting is enlarged to improve the pump's inlet characteristics. As the open loop pump operates on one side of center only, not all controls are available.

Vane Pumps

Denison produce a full range of vane pumps and motors that operate at pressures in excess of 4,500 pounds per square inch ("psi") and vary in size from 0.35 cubic inches to 16 cubic inches, and in displacement from 1 to 250 gallons per minute ("gpm").

Piston Pumps

Denison manufactures a full range of piston pumps at their Marysville, Ohio facility. These specialized pumps operate at pressures as high as 7,250 pounds per square inch ("psi") and vary in size from 0.9 cubic inches to 38.9 cubic inches, and in displacement from 11 to 303 gallons per minute ("gpm").
