What are the uses of PALL filter elements?

Purpose

(1) The pall filter element should be installed at the suction port of the pump:

A surface-type oil filter is generally installed on the suction path of the pump. The purpose of the oil filter is to filter out larger impurity particles to protect the hydraulic pump. In addition, the filtration capacity of the oil filter should be more than twice the pump flow rate, and the pressure loss should be less than 0.02MPa.

(2) The pall filter element is installed on the outlet oil line of the pump:

The purpose of installing the oil filter here is to filter out contaminants that may invade valves and other components. Its filtration accuracy should be 10~15μm, and it should be able to withstand the working pressure and impact pressure on the oil line, and the pressure drop should be less than 0.35MPa. At the same time, a safety valve should be installed to prevent the oil filter from clogging.

(3) The pall filter element is installed on the oil return line of the system: this installation plays an indirect filtering role. Generally, a back pressure valve is installed in parallel with the filter. When the filter is clogged and reaches a certain pressure value, the back pressure valve opens.

(4) The pall filter element is installed on the branch oil line of the system.

(5) Pall filter element independent filtration system: Large hydraulic systems can be equipped with a hydraulic pump and oil filter to form an independent filtration circuit

In the pall filter hydraulic system, in addition to the oil filter required by the entire system, a dedicated fine filter oil is often installed separately in front of some important components (such as servo valves, precision throttle valves, etc.) to ensure they are working properly.
