I have a brushless pump, how do I control it?

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 (click here for PDF). If you have specific questions regarding control functions, especially with programmable controllers (such as the ESCON 50/5) feel free to call Flight Works.


Can I run my pump dry?

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.


Can I use my pump with any fluid, or multiple fluids?

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.


My pump has difficulty priming, or creates cavitation near the fittings/ports. How can I avoid this?

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.


Can I run my pump in reverse?

For the most part, Flight Works pumps can be run in reverse without issue. Note that sometimes, depending on configuration and operating conditions, performance can vary slightly from one direction to the other.


Do I need a pre-pump filter? If so, is there a specific filter I should use?

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.


Can I run my pump above or below its “nominal” or “rated” voltage?

Absolutely, but there are limits on both ends. At very low voltages, the pump may lose efficiency or even shut off. On the other hand, pumps should not be operated above certain parameters. Contact someone at Flight Works to determine these limits (such as max speed and operating current) before attempting to run the pump over its rated voltage.


Can I take my pump apart and put it back together?

Flight Works highly recommends that you do NOT disassemble a pump for any reason, as the reassembly process involves tooling and experience unique to Flight Works manufacturing. If you think the pump needs to be taken apart for any reason, even if it is not functioning, contact Flight Works immediately.


How and where should I mount my pump?

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:

  1. If possible, using something to dampen vibration can help increase the life and reliability of the pump. Rubber grommets in a bracket, a mounting pad, or similar methods will help keep system vibration from disrupting the pump in any way.
  2. When used in a system that will be outdoors, it is best to mount the pump in a more protected location within the system, as exposure to the elements can cause issues with certain configurations.
  3. When mounting a magnetic drive pump, be sure not to place the magnetic coupling section too close to aluminum or other materials that can cause eddy currents. Also, if you expect any g-force loads, mounting the pump perpendicular to the direction of those loads is ideal.
