The Hydrap is a remote control micropositioning device/micromanipulator working with hydraulic liquid medium.

Operating principle:

A precision micrometer grade spindle (pitch 0.5mm) moves a small cross section piston internally into a liquid reservoir.The displaced liquid volume is transferred via a hose towards the receiving actuator part, incorporating a movable membrane with diameter 20 mm as essential component.Thereby the original manual fine screw action is reduced down further by roughly a factor of 100 at the actuator’s output.

The motion is absolutely free of stick/slip, ensuring smoothest operation.
