‘serving the hydraulics industry for over 30 years’
Parker Hannifin, formerly Denison Hydraulics, is a leading industrial manufacturer providing highly engineered
hydraulic fluid power systems and hydraulic components. Denison Hydraulics products have a multitude of applications:
from mobile equipment used in the construction, demolition, agricultural, mining and utilities industries to machinery
used in industrial manufacturing and marine equipment used in both commercial and military sea vessels.
Hydraulic Vane Pumps and Hydraulic Motors
Denison Hydraulics produce a full range of hydraulic vane pumps and hydraulic 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"). Denison Hydraulics hydraulic vane pumps are recognized
as among the strongest products in the hydraulics industry and are distinguished by their unique patented
double-lip design, in which the vane is in contact with the cam ring at two points rather than at one as with the
single-lip design. This double-lip design makes Parker Hannifin HPD's hydraulic vane pumps less susceptible to
contamination than single-lip pumps.
Replace your Denison PV series pumps with our Continental Hydraulics HPV PowerFlow series piston pump. Output
flow sizes are equal to the Denison offering and include 6, 10, 15, 20 and 29 US gallons per minute sizes @ 1750 RPM.
Four standard HPV series control options provide you with the flexibility of matching Denison's offering.
Denison Hydraulics manufactures a full range of hydraulic piston pumps. These specialized hydraulic 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"). They are well-known in the hydraulics
industry for their large-size hydraulic piston pumps, offered under their Gold Cup and Premier Series. Denison
Hydraulics large-size hydraulic piston pumps are distinguished by their proprietary "barrel-bearing" design, which
enables their pumps to run in stable conditions at high speeds and pressures. Their sturdy hydraulic piston pump
construction results in a longer life cycle in severe duty applications such as heavy mining equipment and aircraft
carrier steering systems.
Denison Hydraulics piston pumps are manufactured in the following configurations:
Gold Cup series hydraulic piston pumps for closed and open loop circuits: P6, P7, P8, P11, P14, P24 and P30
World Cup series hydraulic piston pumps: P6W, P6T, P7W, P8W and P8T
Denison Hydraulics also manufactures fixed displacement, dual displacement, and variable displacement radial
piston motors under the Calzoni brand.
Denison Calzoni radial LHST (LOW Speed High Torque) hydraulic motors are available in many configurations including
single and 2 speed versions, with models including the MR series ranging from 33cc up to 7000cc and the MRE series
ranging from 330cc up to 8200cc. Larger displacements are available in the MRT, MRTE and MRTF hydraulic motor series
ranging 7100cc up to 23000cc displacement.
Dual displacement radial piston motors are available in the MRD and MRDE model series and variable displacement
radial piston motors in the MRV and MRVE series range from 300cc up to 8200cc.
Denison Hydraulics manufacture four types of hydraulic valves including: directional control valves which alter
the path of pressurized fluid through the hydraulic systems; pressure control valves which regulate the pressure of
the hydraulic fluid; flow control valves which match the hydraulic fluid's flow with the requirements of the system;
and hydraulic check valves which allow fluid to pass in one direction and not the other. Denison Hydraulics valves
are used in a variety of commercial settings, including injection moulding, metal and material forming, mobile
equipment such as cranes, and marine systems such as ship-mounted winches. They are one of the few hydraulic
manufacturers of flange mounted pressure control valves, a design that enables the hydraulic valve to be attached
directly to another hydraulic component, versus more traditional valve designs that must be connected to the
associated hydraulic components with hydraulic lines, which tends to be more expensive and less effective at
controlling leaks than flange mounting.
Denison Hydraulics high-quality hydraulic manifolds offer a number of features unique to those of competitors.
Their hydraulic manifolds are machined steel or aluminium blocks that act as housing for surface mounted, or
cartridge valves, which control the operation of a wide variety of hydraulic equipment such as presses, bailers,
lifting devices, and mobile machinery and equipment. Hydraulic manifolds are utilized in conjunction with hydraulic
pumps, hydraulic motors, hydraulic cylinders, and hydraulic valves to form a complete hydraulic system.
