Hydraulic pumps

Hydraulic lubrication pumps

Hydraulic lubrication pumps use the machine's own hydraulic circuit as their drive, delivering grease to the lubrication points without a separate motor or air supply. This makes them ideal for mobile machines and equipment that already run on hydraulics: the pump is a single-acting piston unit driven by hydraulic oil with spring return, so every hydraulic pulse delivers a defined dose of grease to the system. With no electrical drive to wire and no compressed air to supply, the hydraulic pump is a clean, self-contained way to add automatic lubrication to a hydraulically powered machine — a natural companion to a progressive distributor . The pump element is a single-acting piston driven by the machine's hydraulic oil, returning under spring force between strokes. Each stroke displaces a defined volume of grease — adjustable from 0.2 to 2 cm³ depending on the configuration — into the lubrication network, building the high pressure needed to reach all the points. Because the drive is the hydraulic circuit, the pump operates wherever the machine works, with no additional energy source to provide.
