WU XU Series Suction Filter
Product Overview
WU XU Series Suction Filter is a cost-effective coarse FILTER, designed as primary protection for the hydraulic system of industrial Machine. Submerged inside the hydraulic oil tank and mounted at the suction port of hydraulic pump, this FILTER has two optional constructions: wire mesh type for WU series and notched wire type for XU series. It intercepts large solid contaminants in hydraulic oil before oil enters the pump, preventing particle abrasion and damage to pump gears, pistons and other precision components of the Machine.
This FILTER features simple structure, large flow capacity and low flow resistance. Threaded pipe connection and flange connection are available to fit different tank layouts. Some models are equipped with built-in bypass valve to avoid pump cavitation. Multiple flow specifications can match different hydraulic power units and industrial Machine. The metal filter element can be cleaned and reused repeatedly, which reduces operating cost of the hydraulic system.

Working Principle
When the Machine starts to operate, hydraulic oil inside the tank flows into WU XU suction FILTER. Large impurities such as metal chips, sand grains and rubber fragments are trapped by wire mesh or notched wire filter cartridge. Clean hydraulic oil flows into the inlet of hydraulic pump.
As contaminants accumulate on the filter element, pressure drop rises. If equipped with bypass valve, the valve will open automatically at preset pressure, allowing oil to bypass the filter temporarily to prevent pump empty suction and cavitation, ensuring continuous operation of the hydraulic system. After long-time service, the metal cartridge can be taken out, cleaned and reinstalled instead of frequent replacement.
Core Advantages
1. Low initial pressure loss and high oil throughput, will not restrict oil supply for the pump, stable operation of the hydraulic system.
2. Two optional structures: WU wire mesh and XU notched wire, flexible to meet different filtration demands of the Machine.
3. Reusable metal filter element, only need regular cleaning, saves long-term spare parts expense.
4. Compact size for installation inside oil tank, threaded and flange connections available for flexible pipeline arrangement.
5. Wide range of flow rates, economical price, widely used as standard primary filter for various hydraulic system.
Application Range
This FILTER is widely applied in the hydraulic system of hydraulic power packs, machine tools, plastic injection machinery, hydraulic presses, metallurgical equipment and small construction Machine. It is installed at pump suction side to block large particulate impurities, protecting hydraulic pumps and extending service life of the whole hydraulic circuit.
