Parker Piston Pumps

Parker piston pumps cover fixed and variable displacement pumps in inline (swashplate) and bent axis designs, for open and closed circuit (hydrostatic) systems in industrial and mobile hydraulics.

The range runs from Oildyne miniature pumps to Gold Cup pumps of around 500 cm³/r, with pressures up to 480 bar.

Variable displacement pumps are available with pressure compensation, load sensing, torque and power limiting, and electronic controls, so flow can be matched to demand to save energy. Many series offer through-drive for multiple pump installations.

Parker Piston Pump Range

Industrial Variable Displacement Pumps

PVplus: Axial piston pumps from 16 to 360 cm³/r, rated up to 420 bar intermittent and 350 bar continuous, with an integrated pre-compression volume to reduce pulsation and noise and a modular design for easy conversion.
PV E design: Denison PV pumps in four sizes (PV6, PV10, PV15 and PV20), with a two-piece cast iron housing, replaceable port and slipper plates, through-shaft capability and a choice of pressure, load sensing and horsepower controls.
PVP: Medium pressure pumps rated up to 250 bar, with a cast iron body, full power through-shaft and pressure, load sensing and power limiting controls.
PAVC: Medium pressure pumps up to 100 cm³/r and 210 bar, with a built-in supercharger for high-speed operation and full pressure rating on water glycol fluids.
PD: Medium pressure industrial pumps from 18 to 140 cm³/r, rated up to 280 bar, with a low noise nine-piston design and proportional electric controls.
DCP: Drive controlled pumps combining a variable speed AC drive, motor and pump (vane or variable axial piston), cutting energy use and noise by reducing speed at part load.

Mobile Variable Displacement Pumps

P1: Medium pressure mobile pumps from 18 to 140 cm³/r, rated up to 280 bar, with full power through-drive.
P2/P3 and eP2/eP3: High pressure open circuit mobile pumps from 60 to 145 cm³/r, rated up to 350 bar, in standard (P2) or supercharged (P3) form and for direct mounting on transmission PTOs. The eP2/eP3 adds electronic closed loop displacement control.
VP1: Variable displacement pumps from 45 to 130 cm³/r, rated up to 420 bar, for direct mounting on truck PTOs with load sensing systems.

Fixed Displacement Bent Axis Pumps

F1 and F2: Truck pumps for PTO mounting, rated up to 400 bar. The F1 covers 12 to 102.9 cm³/r; the F2 twin flow pump gives two separate flows that can be combined, giving three flows from one pump.
F3 and T1: Further fixed displacement bent axis pumps. The T1, for PTO mounting, covers 81 to 121 cm³/r and is rated up to 350 bar.
F11 and F12: Small frame (5 to 19 cm³/r, up to 420 bar) and large frame (sizes 30 to 250, up to 480 bar) bent axis pumps, with ISO, SAE and CETOP mountings.

Closed Circuit (Hydrostatic) Pumps

Gold Cup P6, P7, P8, P11, P14, P24 and P30: Denison Gold Cup pumps for severe duty open and closed circuits, from around 100 to 500 cm³/r, with an integral servo and replenishing pump, a hydraulically controlled rocker cam and a built-in hot oil shuttle.
PC3: Compact variable displacement pumps for medium duty closed circuits, from 7 to 52 cm³/r and up to 300 bar, with a built-in hot oil shuttle, bypass valve and cross port reliefs.
HP1 and HP2: Integrated closed loop pumps with their own reservoir, filter, charge pump, valving and cooling fan. The HP2 has two independently controlled over-centre pumps on one shaft, at 11.5 or 16 cm³/r each, for compact transmissions.

Miniature Piston Pumps

Oildyne: Ultra-compact fixed displacement piston pumps up to 0.865 cm³/r and 276 bar (4,000 psi), for small power units.
