WU-250X80-J High-Flow Hydraulic Suction Strainer for Yuchai YC35
Precision Pump Defense for Yuchai YC35 & YC35-6 Excavators
Specifically engineered to intercept coarse particulates in the suction line, preventing abrasive pump wear.
Optimized for YC35 and YC35-6 architectures to ensure peak breakout force and cycle times.
High-tensile SUS mesh provides superior structural stability and anti-corrosive performance.
Direct technical substitute for Leemin WU-250X80-J, HiFi SH77663, and SF HY 15243.
WU-250X80-J Product Engineering & Operational Value
Safeguarding High-Pressure Hydraulic Circuits
The WU-250X80-J hydraulic strainer serves as the primary barrier at the pump intake. Its role is to ensure that large contaminants from the reservoir do not reach the precision internal components of the hydraulic pump. By maintaining fluid purity at the source, this element helps prevent the micro-pitting of pump gears and pistons-a critical factor for sustaining excavator breakout force and operational efficiency.
Solving Common Filtration Failures
Construction environments subject hydraulic systems to extreme stress. The WU-250X80-J addresses these challenges through an Anti-Cavitation Design. The high-porosity 80-micron mesh provides minimal flow resistance, ensuring the pump is never "starved" of oil, even during cold-start operations. Furthermore, the pleated media configuration significantly increases the effective filtration surface area, allowing for higher debris capacity without a critical pressure drop.
Reinforced Fluid Compatibility
Featuring a rugged internal core and aluminum end caps, the element is built to withstand hydraulic surges and maintain its shape under varying suction pressures. Thanks to its all-metal construction, the WU-250X80-J is chemically compatible with standard mineral-based oils, water glycols, and phosphate esters.

WU-250X80-J Technical FAQ
Q: What is the benefit of the 80-micron rating on the WU-250X80-J?
A: This rating is a nominal balance designed for suction-side protection-fine enough to catch debris that would damage a pump, yet coarse enough to prevent flow restriction and cavitation.
Q: Is the wire mesh filter reusable?
A: Because it is made of stainless steel, it can technically be cleaned using ultrasonic methods. However, for critical industrial maintenance, we recommend replacement to ensure 100% filtration integrity.
Q: When should the suction filter be changed?
A: Standard intervals are every 500 to 1,000 hours, or immediately if pump noise increases or a bypass warning is triggered.
