GP Series Magnetic Return Filter
Product Overview
GP Series Magnetic Return Filter is a tank-top installed return-line FILTER, developed for the hydraulic system of industrial Machine. Mounted on the cover of hydraulic oil tank, this FILTER combines filter medium and permanent magnetic assembly. It purifies return hydraulic oil coming back from the working loop of the Machine, intercepting solid particles and adsorbing ferromagnetic metal wear debris generated inside the hydraulic system. Clean oil flows back into the tank to avoid repeated contamination of hydraulic components.
This FILTER integrates a built-in bypass valve, with optional clogging indicator. When the filter element accumulates contaminants, the bypass valve opens automatically to prevent excessive back pressure and guarantee normal operation of the hydraulic system. Multiple flow specifications and filtration precision grades are available to match various hydraulic power stations and industrial Machine.

Working Principle
When the Machine is in operation, hydraulic oil after driving actuators flows back to the oil tank through the GP magnetic return FILTER. Non-magnetic solid impurities are blocked by the filter medium, while fine iron powder and metal shavings are firmly captured by the built-in high-strength magnetic rod. Purified hydraulic oil enters the oil tank.
As dirt accumulates on the filter element, the pressure difference rises. Once pressure reaches 0.3 MPa, the optional clogging indicator will trigger a warning signal to remind maintenance. If the Machine cannot stop immediately, the built-in bypass valve opens at 0.35 MPa, allowing oil to bypass the filter cartridge temporarily. This prevents excessive back pressure and protects the whole hydraulic system. During maintenance, you can take out the filter element and magnetic rod for cleaning directly from the tank top without draining all hydraulic oil.
Core Advantages
1. Dual filtration structure: magnetic rod adsorbs tiny ferrous particles while filter medium traps solid contaminants, effectively improving oil cleanliness of the hydraulic system.
2. Built-in bypass valve plus optional clogging indicator provide reliable protection, avoiding backpressure damage to the hydraulic system.
3. Simple maintenance: replace filter element and clean magnetic assembly from tank top, no full oil draining required, reducing downtime of the Machine.
4. Compact flange structure, good sealing performance, easy installation on standard hydraulic oil tanks.
5. Wide selection of flow rates and precision, strong interchangeability, perfect for heavy-duty hydraulic system with metal wear.
Application Range
This FILTER is widely used in the hydraulic system of hydraulic power packs, machine tools, metallurgical machinery, mining equipment, injection molding machines, hydraulic presses and other industrial Machine. It performs return oil purification and reduces circulating metal pollutants, suitable for new equipment assembly and routine maintenance spare replacement.
