How do I prime my 230 Micro Pump^™ system?

The 230 micro pump™ is self-priming at full stroke, which means it can draw fluid into the fluid inlet even if there is air present in the line. If you have an adjustable output pump, the “P” on the adjustment knob must line up with the mark on the pump body. A fixed output pump will always run at full stroke.

If there is an issue with a pump not priming fast enough, increase the cycle rate momentarily. It can take a longer time to prime large pump stacks or long fluid inlet lines as the pumps only displace 20-60µL per stroke. The pump is fully primed when there are no air bubbles in the fluid outlet line.
