Pneumatically operated piston pumps
The pumps are pressurized with compressed air via a directional control valve. The delivery piston is moved by the compressed air operated piston. The lubricant in front of the delivery piston is dispensed. The pressure needed to feed the lubricant is generated in accordance with the ratio of the operating piston's surface to that of the delivery piston.
SKF has the right piston pumps for all types of systems and lubricants. In the table you can find the technical details of these piston pumps.
