Original MANN-FILTER Hydraulic filter WD 11 002 – For industry, agricultural and construction machinery

MANN‑FILTER WD 11 002 Hydraulic Filter

The WD 11 002 is a high‑performance hydraulic filter designed for industrial, agricultural and construction machinery. It delivers reliable protection for hydraulic systems that operate under demanding conditions, ensuring longevity of pumps, valves and actuators.

Key Design Features

• Robust Construction: The filter housing is made from durable polypropylene with a reinforced steel mounting flange. This construction resists corrosion and withstands high pressure differentials.
• High‑Efficiency Media: Inside the cartridge, a multi‑layer filtration media captures particles as small as 5 µm while maintaining low flow resistance. The media is engineered to retain oil contaminants without compromising hydraulic performance.
• Easy Installation: The filter uses a standard M40x2 threaded mounting system, allowing quick and secure attachment to most hydraulic lines. Its spin‑on design eliminates the need for additional fittings or adapters.
• Wide Operating Range: Rated for temperatures from –20 °C to +120 °C, the WD 11 002 remains stable in both cold and hot environments typical of off‑highway equipment.
• Long Service Life: With a design life of up to 12,000 operating hours under normal conditions, this filter reduces maintenance intervals and downtime.

Applications

The WD 11 002 is engineered for use in a variety of heavy‑duty hydraulic systems:

• Industrial machinery such as mixers, presses and conveyor drives.
• Agricultural equipment including tractors, harvesters and irrigation pumps.
• Construction vehicles like excavators, loaders, bulldozers and backhoes.
• Off‑highway machines operating in dusty or muddy environments where contamination risk is high.

Performance Characteristics

Installation and Maintenance Guidelines

1. Preparation: Ensure the hydraulic system is shut down and depressurized. Drain any residual fluid if necessary.
2. Removal of Old Filter: Unscrew the existing filter using a suitable wrench, taking care not to damage the mounting flange.
3. Cleaning: Wipe the mounting surface with a clean, lint‑free cloth to remove dust or debris. Do not use solvents that could compromise the seal.
4. Installation: Align the new WD 11 002 filter and tighten clockwise until snug. Verify that the threaded connection is secure but avoid overtightening which may damage threads.
5. System Re‑pressurization: Gradually re‑introduce hydraulic fluid, monitoring for leaks around the mounting flange.
6. Periodic Inspection: Check filter condition at regular intervals. Replace when pressure differential exceeds 10 bar or when visual inspection shows media clogging.

Compatibility Overview

The WD 11 002 is compatible with a broad range of hydraulic systems that use standard M40x2 fittings. It has been validated for use in:

• Deutz‑Fahr AGROKID, AGROLUX and Agroplus series.
• SAME DORADO and SAME 3.1L models.
• Volvo T 3.9 and other off‑highway tractors.
• Various automatic transmission hydraulic circuits requiring high‑pressure filtration.

Why Choose the WD 11 002?

• Reliability: Proven track record in harsh operating environments ensures consistent protection for critical components.
• Efficiency: Low pressure drop maintains system performance while delivering superior filtration.
• Sustainability: Designed for extended service life, reducing waste and maintenance costs.
• Versatility: Suitable for a wide array of machinery across multiple industries.

Conclusion

The MANN‑FILTER WD 11 002 Hydraulic Filter represents the pinnacle of filtration technology for heavy‑duty hydraulic systems. Its robust design, high efficiency media and ease of installation make it an indispensable component for any operation that demands reliable performance under challenging conditions.
