NJU TANK MOUNTED SUCTION FILTER SERIES

    The NJU-series filters are widely used in hydraulic systems. The filter can be in stalled on the top or at the side of the tank. The filter head should be out of tank and the filter bowl should be inserted from side or top of the tank into oil. The outlet is connected with pump outlet.25~160 L/min type has combine removable  flange, the working height can be adjusted in order to make the tank totally obdurate and that way can prevent the contamination from getting into the tank. During maintenance, open the filter cover, take out the filter element together with sludge cup and clean them. A by-pass valve and a vacuum are incorporated with the filter.  When the pressure drop across the filter element reaches 0.018MPa, the indicator gives signals showing maintenance shall be done. If no service is done and as the pressure drop rises to 0.02MPa, the by-pass valve will open to ensure oil flow into pump.
