Vane Pumps and Motors
We 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"). Our vane pumps are recognized as among the strongest products in the hydraulics industry and are distinguished by our 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 vane pumps less susceptible to contamination than single-lip pumps.

Piston Pumps and Motors
We manufacture a full range of piston pumps at our 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"). We are well-known in the hydraulics industry for our large-size piston pumps, offered under our Gold Cup and Premier Series.
Our large-size piston pumps are distinguished by our proprietary "barrel-bearing" design, which enables our pumps to run in stable conditions at high speeds and pressures. Our sturdy piston pump construction results in a longer life cycle in severe duty applications such as heavy mining equipment and aircraft carrier steering systems.

Radial Piston Motors
We manufacture fixed displacement, dual displacement, and variable
displacement radial piston motors through our modern Bologna, Italy
manufacturing facility. We offer our customers components that are less
standard, but more suitable to respond to the customer's specific
requirements. Our radial piston motor products respond to the hydraulic
market's evolution towards products offering optimum performance and maximum
efficiency.
