Detailed Product Description
The Wix 51551 hydraulic filter is built to meet the demands of heavy-duty hydraulic systems commonly found in commercial vehicles and industrial equipment. Its enhanced cellulose media provides effective filtration at a 10-micron rating, capturing fine particles to protect hydraulic components from wear and damage. The filter’s beta ratio of 2/20/75=5/13/18 indicates its efficiency in removing contaminants at various particle sizes, ensuring system cleanliness and longevity.
With a burst pressure of 440 psi, the filter maintains structural integrity under high-pressure conditions. The spin-on design simplifies replacement, while the 1-12 thread size and closed inner diameter top ensure a secure fit. Although this filter does not include an anti-drain back valve or bypass relief valve, it is engineered for systems where these features are not required.
Applications and Problem Solving
- Protects hydraulic pumps and valves from particulate contamination
- Prevents premature wear in hydraulic cylinders and motors
- Maintains hydraulic fluid cleanliness to improve system efficiency
- Reduces risk of hydraulic system failure due to clogged filters
- Supports consistent flow rates between 12 and 16 gpm in heavy-duty applications
Installation Notes and Tips
When installing the Wix 51551 hydraulic filter, ensure the system is depressurized to avoid fluid spray. The spin-on design allows for straightforward replacement; apply a thin layer of clean hydraulic fluid to the gasket before threading the filter onto the housing. Tighten according to manufacturer specifications to prevent leaks. Regular inspection and timely replacement based on operating hours or contamination levels will help maintain optimal hydraulic system performance.
