Hydraulics

Accumulators Parker offers three types of hydro-pneumatic accumulators; piston, bladder and diaphragm, each with particular advantages depending on the industrial application. Each accumulator regulates the performance of a hydraulic system by providing an additional volume of system fluid, pressurized by an external gas supply. See all Accumulators	Actuators An actuator is designed to convert fluid power into rotary or linear motion for applications such as upending, turning, roll-over, tilting, indexing, mixing, valve operating, and tensioning. Parker offers a wide selection of pneumatic, hydraulic and vane rotary actuators with low leak rates, high durability, lubrication options, and a range of torque out puts and rotations. See all Actuators	Cartridge Valves A cartridge valve is an ideal choice for any hydraulic control function, whether it's a threaded or slip-in design, such as relief valves, sequence valves, check valves, pressure-reducing valves, pilot-operated, load-control, counterbalance, flow-control, solenoid, or electro-proportional. In addition, one or more cartridge valves in a manifold can be custom built to meet specific requirements. See all Cartridge Valves	Cylinders Parker manufactures and The Hope Group distributes a vast range of standard and special single and double acting tie rod, roundline, welded, telescoping, and 'mill' type hydraulic cylinders, which meet ISO, DIN, NFPA, ANSI and JIC standards. See all Cylinders

Filtration Proper filtration maximizes the reliability of hydraulic systems and components against fluid contaminants. The full line of pressure and return line filters from Parker enhances machine life, reduces maintenance and lowers costs. High, medium and low pressure filters are available, as well as portable filter carts and replacement elements. See all Filtration	Gear Pumps The simplicity of a fixed displacement gear pump is derived from the pressure created through the meshing of the gear teeth, which forces fluid around the gears to pressurize the outlet side. Modern gear pumps are not as noisy as in the past and Parker has a wide range of sizes from which to select. See all Gear Pumps	Hydrostatic Hydrostatic transmissions, for off highway vehicle propulsion and other rotary power applications, with fixed or variable hydraulic pumps and fixed or variable motor combinations provide an extended range of motor speeds and torques, with operating pressure up to 5,000 psi continuous and 6,000 psi intermittent. See Hydrostatic Transmissions	Manifolds Hydraulic valve manifolds from Parker are available from single cartridge valve manifolds to integrated hydraulic circuit manifolds, including inline, circuit block, and cartridge block manifolds. Also available are conventional remote mounted two, three and five valve manifolds for static pressure, liquid level and flow measurement applications. See all Manifolds

Motors Any rotary power application can be addressed from Parker's extensive line of hydraulic motors, which include low speed high torque motors, such as gerotors and radial piston designs. Parker also offers high speed motors, such as piston, fixed & variable displacement, vane, and gear motors. See all Motors	Power Take Off The auxiliary power market will benefit from the complete line of cast iron, 6-bolt, 8-bolt, 10-bolt, countershaft, split-shaft, power-shift, and front-mount applications from Parker. Air, cable, lever or electric shift options, overspeed control, and flanges for direct or remote mounting to hydraulic pumps are additional features. See Power Take Off	Power Units The Hope Group offers custom designed and built hydraulic power units as well as Parker's self-contained pre-plumbed HPU's for industrial applications. In sizes from five to 40 gallon, up to 20HP and 3,000 PSI, gear, vane or piston operated, there are very quick turn-around times on Parker hydraulic power units. See all Power Units	Pumps Energy efficient hydraulic pumps from Parker include fixed or variable displacement models in piston, vane and gear pumps, available in high pressure or low pressure varieties for a wide range of open loop or closed loop applications. These pumps are available with a full complement of electronic and computer controls. See all Pumps
Valves Industrial and mobile valves from Parker range from simple in-line designs to high performance sectional and manifold mounted directional and proportional valves. In-line products include flow and pressure controls, checks, ball and shear seal valves; plus, manifold mounted pressure, directional, proportional control and servo valves. See all Valves
