PV(R) Micropump

Pneumatically actuated micro pump

The compressed air controlled by a 3/2-way valve actuates the delivery piston, which discharges the respective output on the basis of its displacement. The travel of the stroke, and thus the metering of the delivery rate, is increased or decreased with setting rings. The compressed-air line to the pump needs to be relieved of pressure after each actuation so the delivery piston can return to its initial position.

The micro pump is specially designed for minimal quantity lubrication, and, namely, only for cases in which oil is to be sprayed on with compressed air.
