Technical Data
Parker F12 Bent Axis Piston Pump
The Parker F12 series is a heavy-duty bent axis, fixed displacement piston pump built for the toughest open and closed loop hydraulic circuits. Available across eleven frame sizes from 30 to 250 cc, the F12 combines a compact 40° bent-axis design with laminated piston rings and a unique timing gear set-up that synchronises shaft and cylinder barrel — giving it strong resistance to high G-forces and torsional vibration. The 7 or 9 piston design delivers high start-up torque and smooth running, while a simple, low parts-count construction keeps it reliable and serviceable in the field. Suited to fan drives, cranes, winches, and a wide range of mobile and industrial applications. Enquire with our team for stock availability and pricing on the frame size you need.
