Single-action 55i pump for use with multi-line lubrication systems


The positive-displacement, single-action 55i pumps are fully adjustable by means of manually modifying the angle of the rocker arm to the cam. The pump operation is a two-stage process. As the camshaft rotates, the cam mechanically forces the pump plunger forward, displacing a measured volume of oil. On the second or return stroke, a spring assists the plunger to return for prime. All pump elements are designed with a pushbutton for manual pre-lubrication.
