Camshaft-operated piston pump 55i

For use in 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 push button for manual pre-lubrication.
