Not sure Brit, depends on back pressure.
Der- Some Mags run fine without fluid, some have high end vibration, depends on final balance. The fluid stops this vibration, hence "fluid stabilized" comment.
Running MAG open for short time is fine, long term can causes bearings to crack.
It is best to not run dry, if possible. I did run a MAG for over a week dry, didn't know the damn thing was on.
I sent the address to sales for the review pumps.
All the sales staff was away last week, for training. There are new customs rules and procedures for US shipments now. I am no longer to ship direct anymore, but will ask what went out.
Off to work, later all
