Collant filter and oil coalescer

Machine tool coolant processing apparatus for cleaning a coolant fluid and separating the coolant fluid from oils having a lower density comprising, in combination, a frame having an upper portion, an accumulation reservoir defined on said frame below said upper portion, first and second electrically operated pumps mounted on said frame each having an inlet and an outlet, a separation reservoir mounted on said frame upper portion, an inlet and an outlet defined in said separator reservoir, said separation reservoir inlet and outlet being spaced from each other and a liquid flow path defined therebetween, a coolant fluid and oil separator located within said separation reservoir within said flow path between said separation reservoir inlet and outlet, said separator including a horizontal weir whereby oils having a lighter density than the coolant fluid flow over said weir, a discharge conduit receiving oils flowing over said weir removing said oils from said separator and said separation reservoir, said separation reservoir outlet communicating with said accumulation reservoir, a first conduit connected to said first pump inlet for receiving coolant to be processed, a second conduit connected to said first pump outlet in communication with said separation reservoir inlet, a fine filter mounted on said frame having an inlet and an outlet, a third conduit connecting said second pump inlet to said accumulation reservoir, a fourth conduit connecting said second pump outlet to said fine filter inlet, a fifth conduit attached to said fine filter outlet for supplying processed coolant, and control means for said second pump sensing the coolant level within said accumulation reservoir and controlling operation of said second pump in accordance with the coolant level within said accumulation reservoir.
