F12-040-MF-IV-Z-000-000-0 Parker Hydraulic Pump 40cc 500bar

Product Overview

The F12 series is a member of the Parker F11/F12 heavy-duty bent-axis fixed displacement axial piston motor/pump family. The F12 series shares the same 40° bent-axis design philosophy as the F11 series, featuring unique spherical pistons with laminated piston rings, and offers a displacement range from 30 cc/rev to 250 cc/rev. F12 units are fixed displacement heavy-duty motors/pumps that can be used in numerous applications in both open and closed loop circuits.

The F12 series delivers maximum intermittent operating pressures up to 500 bar and continuous operating pressures up to 450 bar. Core design features include precision gear synchronization and double tapered roller bearings, providing exceptional vibration resistance and high radial load capacity. The F12 series features face and shaft port plate designs for simple, compact construction with high precision fluid distribution.

Our product provides a fully interchangeable direct replacement for the original Parker F12 series pump, with identical mounting dimensions, port specifications, and shaft configurations. Every unit undergoes 100% simulated duty-cycle testing—performance-validated under rated pressure, peak pressure, and full speed range to ensure volumetric efficiency, mechanical efficiency, flow output, noise levels, and thermal characteristics meet or exceed original OEM specifications.

Key Technical Advantages

1. 40° Bent-Axis Design with Spherical Pistons
The F12 series features Parker’s signature 40° bent-axis design with unique spherical pistons and laminated piston rings. The 40° angle between the drive shaft and cylinder barrel axis delivers a compact, lightweight structure. The spherical piston design significantly reduces internal leakage, improves volumetric efficiency, and provides excellent thermal shock resistance.

2. Gear Synchronization & Double Tapered Bearings
Precision timing gears ensure exact phase synchronization between shaft and cylinder barrel, providing exceptional tolerance to high G-forces and torsional vibrations. Double tapered roller bearings deliver high radial load capacity.

3. Ultra-High Pressure Capability
The F12-040 delivers maximum intermittent pressure of 500 bar and continuous working pressure of 450 bar. Features face and shaft port plate designs for simple, compact construction with high precision fluid distribution.

4. High Speed Capability
Maximum intermittent speed of 6,900 rpm and continuous speed of 6,300 rpm. The lightweight piston design and compact rotating components enable the F12 series to withstand extremely high speeds.

5. Low Internal Leakage & High Efficiency
Laminated piston rings minimize internal leakage while delivering high overall efficiency. The 7 or 9-piston design provides smooth operation.

Expert Maintenance Tips

1. Shaft seals and all O-rings must be replaced after every disassembly.

2. Pre-lubricate all moving parts with clean hydraulic fluid before assembly.

3. Prime the pump housing with hydraulic oil before initial start-up to prevent dry-start damage.

4. Monitor case drain flow regularly—an abnormal increase indicates potential piston ring or cylinder barrel wear.

5. Recommended maximum system operating temperature should not exceed 80°C; drain oil temperature should not exceed 115°C.

6. Ensure hydraulic system filtration meets β₁₀ ≥ 75 (ISO 4406 cleanliness code不低于 18/16/13).
