LEEMIN SRLF Series DUPLEX Large Flow Rate Oil Return Filter SRLF-330 SRLF-1300
The feature of duplex oil strainer allows for continuous operation when changing elements due to clogging caused by contaminants. After opening the balance valve and turning the directional valve, the other filter begins to work, thus a clogged element should be changed in time.
These series of duplex basket strainer have a high flow range from 1300 l/min to 15000 l/min with maximum pressure 1.6 Mpa. They are widely used in the hydraulic systems of heavy-duty mining and metallurgical machines.
DRLF series filter is used in return line, it can remove all the contaminants from the hydraulic system, keeping the oil back to the tank clean. The element of this aeries is made of glass fiber, it has high efficience and filtration, large dirt capacity and lower initial pressure drop. There is a by-pass valve and a contamination indicator. The indicator will act when pressure dro across filter element attains 0.35Mpa. The element should be cleaned cleaned or changed in time, if the system can not be stopped or nobody replaces element, the by-pass valve will open to protect the hydraulic system safe.
