Flight Works pumps are capable of “dry priming” which means they can draw fluid without being pre-filled. However, the pump should not operate dry for more than 30-60 seconds, as this can damage the internal components.
First you should have either a brushless speed controller sold by Flight Works or an equivalent method of control in your system. After that most of the information you need can be found in our Brushless Control Instructions
Each Flight Works pump has been configured with materials deemed compatible with the customer’s primary fluid. Whether it can be used with any other fluids may depend on the configuration and the alternate fluid. Contact Flight Works to confirm compatibility before using any additional fluids.

Filtration is extremely important when using Flight Works micro gear pumps, as the components and clearances are extremely small and minuscule particulates can cause damage if not properly filtered. A filter with a 25-50 micron rating or better should be installed before the pump (the finer the better). In closed-loop systems, installing a filter after the pump can also be beneficial, as it will prevent any “break-in” period from contaminating the system.
Oftentimes, a pump can struggle to prime, or can create cavitation, if there is small air leak in the system. Check that any fittings, valves, tubing, etc. are all sealed and firmly in place. It may be necessary to tighten fittings or use a pipe thread tape to help prevent air from entering the system.
As far as direction is concerned, Flight Works pumps will work equally well oriented in any direction (even upside down). However, there are a few helpful tips to consider when mounting the pump:
