SH74004 Hydraulic Return Filter Cartridge
Precision Engineered for Leitner LH250 and Heavy-Duty Industrial Hydraulic Systems
SH74004 Detailed Product Description
Problem-Driven Engineering
Return line contamination is a silent killer of hydraulic pumps and actuators. In specialized machinery like the Leitner LH250, the hydraulic fluid must remain free of metallic shavings and coarse debris to prevent system stiction. The SH74004 provides a robust barrier, ensuring that oil returning to the reservoir is filtered to professional standards, extending the service life of high-value hydraulic components.
How a Wire Mesh Return Filter Works
The SH74004 utilizes a 25-micron (25µ) wire mesh media. Unlike cellulose, wire mesh provides excellent structural integrity and can withstand high differential pressures (up to 20 bar collapse pressure). As shown in SH74004 BBRM (19).JPG, the pleated design maximizes the filtration surface area, allowing high flow rates with minimal pressure drop.

SH74004 Technical FAQ
A: Yes, the primary advantage of wire mesh media is its ability to be cleaned (ultrasonic or solvent) and reused, reducing long-term costs.
A: It ensures that if the filter is clogged, fluid returns to the tank to prevent high back-pressure that could rupture other seals.
A: In return lines, cold oil can create immense pressure spikes. This rating ensures the filter maintains its structural integrity.
A: Check contamination indicators daily and replace/clean during major seasonal maintenance per the service manual.
