Suction/Pressure/Return Line Custom Industrial Hydraulic Oil Filter Element

A: Hydraulic system oil filter elements are installed inside hydraulic filters and oil filtration assemblies, tasked with purifying circulating hydraulic oil. They trap metallic wear debris and mechanical impurities inside hydraulic circuits, lowering component abrasive wear to extend the whole hydraulic system service life.

1. Suction Line Hydraulic Oil Filter

Mounting spot: between oil tank and hydraulic pump inlet, or submerged inside the oil tank

Core purpose: primary protective component to block coarse contaminants before fluid enters the hydraulic pump

Filtration precision: 100~180μm (coarse filtration, prevents large hard particles from damaging pump internal structures)

2. Pressure Line Hydraulic Oil Filter

Mounting spot: high-pressure pipeline downstream from the hydraulic pump

Core purpose: fine-grade purification that controls overall oil contamination levels, shields downstream precision hydraulic parts while delivering secondary pump protection

Filtration precision: 5~10μm (fine filtration, intercepts tiny abrasive particulates)

3. Return Line Hydraulic Oil Filter

Mounting spot: pipeline for oil flowing back to the reservoir

Core purpose: capture wear particles produced by actuator operation, stop pollutants from re-entering the tank and being recirculated into pumping equipment

Allowable pressure differential: 0.3–0.5MPa (varies by rated pressure grade)

Filtration precision: customized according to site hydraulic oil cleanliness standards

Applicable for hydraulic loop maintenance across engineering machinery, industrial hydraulic stations, injection molding equipment, metallurgical hydraulic devices and factory automated hydraulic actuators.
