Hydraulic filtration systems

USP

Eaton's stationary off-line filter units are designed for the oil-service for gears with lubricants of high viscosity for the off-line filtration. The compact construction on a base plate without tube is the precondition for the small dimensions and the high reliability.  The device is equipped with a gear pump driven by an e-motor. The circulation filter units US 10-640 take oil from a reservoir connected by a hose to clean it from contaminants (dirt and water). The purified oil is pumped into the intended reservoir. The contaminants accumulate in the filter. The unit works without supervision after the start. The maximum allowable dirt particle size of the working fluid should be < 200μm. Larger dirt particles cause a premature wear of the gear pump.

The stationary off-line filter units in the US series are used for the fine  filtration, filling or flushing of hydraulic systems. The filter units are equipped with a gear pump driven by an electric motor. They are available for various volume flow rates, in different sizes, and with different micron ratings for the required fluid cleanliness.
