DA Lubricators are manual grease and oil, double-action piston high pressure pumps. For bearings that require an application of lubricant infrequently, the manually-operated pumping unit is used, and may be located on the machine or at any convenient point nearby.
These units consist of a double-acting piston pump, reciprocated by a hand lever through a rack-and-gear segment. A quick-fill connection provides a convenient means of filling the reservoir, and an inlet filter screen gives added protection against the entry of dirt.
Where oil is employed, a cork float with oil level rod replaces the grease follower plate. Three sizes of reservoirs provide a supply of lubricant adequate for the number of bearings being lubricated.
