• The laminated piston ring offers important advantages such as unbeatable efficiency and thermal shock resistance
• The unique piston locking, timing gear and bearing set-up as well as the limited number of parts add up to a very robust design with long service life and, above all, proven reliability.
• The 40° angle between shaft and cylinder barrel allows for a very compact, lightweight motor/ pump.
• The motor version has highly engineered valve plates for high speed and low noise
• The pump version has highly engineered valve plates for increased self priming speed and low noise, available with left and right hand rotation.
• The F11's and F12's have a simple and straight-forward design with very few moving parts,making them very reliable motors/pumps.
• Our unique timing gear design synchronizes shaft and cylinder barrel, making the F11/F12 very tolerant to high 'G' forces and torsional vibrations.
• Heavy duty roller bearings permit substantial external axial and radial shaft loads.

3. Performance Advantages
• High Efficiency:
• Optimized vane geometry and flow paths reduce energy loss (>90% efficiency).
• Low noise operation (≤85 dB(A)) due to precision-machined components.
• Durability:
• M4SC variant: Hardened shafts and corrosion-resistant seals for harsh environments (e.g., marine, mining).
• Dual-lip seals prevent oil leakage and contamination.
• Versatility:
• Bidirectional rotation(clockwise/counterclockwise) via port A/B switching.
• Compatible with multiple oil types (mineral/synthetic hydraulic fluids).
------
4. Key Applications
• Industrial Equipment:
• Conveyor drives, cranes, and mixers in metallurgy/cement plants.
• Mobile Machinery:
• Steering systems for excavators, loaders, and agricultural tractors.
• Specialized Environments:
• Offshore platforms (salt-resistant coating on M4SC models).
• Coal mining (shock-resistant design for vibrations).
------
5. Installation & Maintenance
• Port Configuration:
• SAE 4-bolt, UNC thread, or metric thread options.
• Optional integrated relief valves for pressure control.
• Service Recommendations:
• Replace hydraulic oil every 1,000–3,000 hours (depending on operating conditions).
• Inspect seals and bearings biannually for wear.
------
6. Customization & Support
• Tailored Solutions:
• Adjustable displacement (43.9–317 ml/rev) and pressure ratings.
• Special coatings for extreme temperatures (-30°C to +120°C).
• Supplier Network:
• Global availability through distributors (e.g., Denison Hydraulics, Shanghai Jinhui).
• Technical support for system integration and troubleshooting.
