Technical Product Description
What is the function of the WU-400X80F-J Hydraulic Filter?
The WU-400X80F-J is a specialized suction filter element designed to be submerged or installed in the hydraulic reservoir. Its primary role is to act as the first line of defense for the hydraulic pump, intercepting coarse particles that could cause catastrophic pump failure or cavitation. By maintaining the cleanliness of the fluid at the intake stage, this filter ensures the longevity of the entire hydraulic circuit in demanding environments like construction and mining.
Solving Reliability Challenges in XCMG and DINGLI Machinery
- Pump Cavitation Prevention: The WU-400X80F-J is designed with a high-flow pleated structure to ensure the pump always receives a steady supply of oil, even in cold-start conditions.
- Extreme Condition Durability: Whether working in the dusty environments typical for XCMG ZL50G loaders or the precision requirements of DINGLI boom lifts, this filter provides consistent performance.
- TCO Reduction: By preventing large debris from reaching sensitive valves, this filter significantly reduces unplanned downtime and expensive component overhauls.

Frequently Asked Questions
Q: Is the WU-400X80F-J a suction or return filter?
A: This is a suction filter, used at the intake of the hydraulic pump to prevent large contaminants from entering.
Q: Can this filter replace the HIFI SH 77652?
A: Yes, it is a 1:1 technical match designed to meet the same flow and filtration requirements.
Q: Is the filter media cleanable?
A: While wire mesh can often be cleaned, we recommend replacement at service intervals to ensure 100% protection and avoid microscopic fatigue.
Q: What is the benefit of the pleated design?
A: Pleats increase surface area, allowing for higher dirt-holding capacity and lower resistance to oil flow.
