How it works:

Memolub®HPS is a fully self-contained electromechanical lubricator which utilizes a patented positive displacement pump.

The main components are a motor, gearbox, piston pump, microprocessor and a 4.5v battery power pack. A cam fitted to the outlet gears drives a lever, which lifts the hollow piston and simultaneously compresses a spring. When the piston reaches the top of its stroke, the lever is freed from the cam and the piston begins its downward (working) stroke, driven by the spring. Lubricant is sucked into the chamber formed above the piston during its downward ejection stroke preparing it for its next cycle.

The cycle interval and output quantity can be easily setup using the memo fittings (see picture below).
