Parker Hannifin, formerly Denison Hydraulics, is a leading industrial manufacturer providing highly engineered hydraulic fluid power systems.
Parker Denison Hydraulic pumps have a multitude of applications, ranging from: construction mobile equipment, demolition, agricultural, mining and utilities industries. In addition the pumps can be used in industrial manufacturing and marine equipment, including commercial and military sea vessels.
Often referred to as “Parker Denison”, Denison Hydraulics branded products include a full range of hydraulic vane pumps and hydraulic motors operating at pressures in excess of 4,500 pounds per square inch (“psi”). Sizes from 0.35 cubic inches to 16 cubic inches. Displacement from 1 to 250 gallons per minute (“gpm”).
A full range of Denison hydraulic piston pumps are also on offer. These specialised hydraulic pumps operate at pressures as high as 7,250 pounds per square inch (“psi”). Sizes from 0.9 cubic inches to 38.9 cubic inches. Displacement from 11 to 303 gallons per minute (“gpm”). They are well-known in the hydraulics industry for their large hydraulic piston pumps, offered under their Gold Cup and Premier Series brands.
The Parker Denison Hydraulics range also includes the following valves:
Pressure relief valves;
Denison valves are used in a variety of commercial settings, including: injection moulding, metal and material forming, mobile crane equipment, and marine systems, such as ship-mounted winches. They are one of the few hydraulic manufacturers of flange mounted pressure control valves. This design enables the hydraulic valve to attach directly to another hydraulic component, as opposed to more traditional valve designs, where the associated hydraulic components connect using hydraulic lines. The latter is more expensive and less effective at controlling leaks than flange mounting.
