WF Hydraulic Suction Filter
Product Overview
WF Hydraulic Suction Filter is a compact submerged coarse FILTER, serving as the primary protective component for the hydraulic system of industrial Machine. It can be mounted on the top, side or bottom of hydraulic oil tank, with filter cylinder submerged under oil level and filter head exposed outside the tank. It intercepts large solid contaminants before hydraulic oil enters the hydraulic pump, protecting pump gears, pistons and other precision parts of the Machine from abrasive wear.
This FILTER is equipped with optional self‑sealing valve, bypass valve and clogging indicator. The self‑sealing valve can block oil flow when replacing filter element, avoiding oil spill from the tank and simplifying maintenance of the Machine. Multiple thread connection sizes are available to match different hydraulic power units and industrial Machine. Metal filter element can be cleaned and reused, reducing operating cost of the hydraulic system.

Working Principle
When the Machine starts, hydraulic pump draws oil from oil tank. Hydraulic oil flows through WF suction FILTER. Metal chips, rubber debris and dust particles are trapped by the metal filter element, clean oil flows into pump suction port.
As dirt accumulates on filter element, vacuum degree rises. If fitted with bypass valve, it opens automatically at preset vacuum to avoid pump cavitation and keep the hydraulic system running continuously. The self‑sealing valve will close automatically when filter head is removed, preventing oil leakage during filter element replacement. The metal cartridge can be taken out, cleaned and reused for the Machine.
Core Advantages
1. Flexible mounting position (top / side / bottom of tank), optimizes pipeline layout of the hydraulic system, saves installation space for the Machine.
2. Optional self‑sealing valve prevents oil spill during maintenance, greatly reduces downtime and oil waste of the hydraulic system.
3. Built‑in optional bypass valve protects hydraulic pump from cavitation, improves operation reliability of the Machine.
4. Reusable metal filter element, no frequent replacement required, cuts spare‑parts cost for the hydraulic system.
5. Low flow resistance and large oil‑passing capacity, will not cause insufficient oil supply for hydraulic pump. Wide thread size options, high universality for various industrial Machine.
Application Range
This FILTER is widely applied in the hydraulic system of hydraulic power packs, machine tools, plastic machinery, hydraulic presses, metallurgical equipment and other industrial Machine. It works as suction‑side coarse filtration to protect hydraulic pumps, suitable for new equipment assembly and routine spare‑part replacement.
