+Mark Dierking Ideally either pump will function as intended inside a given operational range assuming proper, regular maintenance. This being said, the shaft and bearings of an unbalanced vane pump might be oversized (ie: more expensive and heavier) in comparison to a similarly sized balanced vane pump to account for the uneven loading.

Yes, vane pumps have less leakage than a gear pump because the sliding vanes provide a better seal than the tolerance between the gears of a gear pump. Also, while incredibly simple and inexpensive, gear pumps are notoriously noisy.
Vane pumps are usually quieter than gear pumps too, but vane pumps are usually not rated above 2000psi operating where gear pumps can supply pressures over twice that.
Vane pumps have many advantages over internal gear pumps - namely viscosity flexibility, dry run capability, solids handling ability, and consistent flow rates due to the unique sliding-vane pump design where the vanes self-adjust for wear.
@@Joscope It would be worthwhile to make the distinction between internal and external gear pumps. Sliding vane pumps are comparable to internal gear pumps with their pressure ratings, and in addition to often being quieter, vane pumps offer many additional benefits for users.
Theoretically yes, however, like gear pumps, some manufacturers include design features that make them more efficient or quieter in a specified direction. Additionally the suction port is often a different diameter than the output.

I am wowed with how clear and full of detail your lectures are. Amazing!
Thanks very much for the comprehensive info. Gave me so much information about the variable vane pump in my Amada HA250 bandsaw 👍👍
As always, 11/10 video. Thanks for uploading
Good stuff! I was blind and now I see. This is going straight onto my resume :O)
Very nicely explained the whole topic, thnks
Love from India 💌
Great explanation!

Excellent lecture. Was wondering about the difference in service life between the balanced and unbalanced versions?

These are great lectures, just one question whats the advantage of a fixed vane pump over a gear pump? is it just efficiency? Thanks

Why, vane pump make noise , within short span ? Compared to gear pump
How to arrest the noise in vane pump and reason @jim pytel
thanks
Will they function bidirectionally?
Theoretically yes, however, like gear pumps, some manufacturers include design features that make them more efficient or quieter in a specified direction. Additionally the suction port is often a different diameter than the output.
