AaWELL EXPLINED T Q SIR

[@markdierking9347]

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

[@bigbadtech]

+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. If they were undersized the service life would notably suffer.

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

[@bigbadtech]

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.

[@Joscope]

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.

[@BlackmerGlobal]

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.

[@BlackmerGlobal]

@@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.

Why, vane pump make noise , within short span ? Compared to gear pump How to arrest the noise in vane pump and reason @jim pytel

[@phamtuminh1477]

thanks

[@joeycad]

Will they function bidirectionally?

[@bigbadtech]

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.

[@joeycad]

@@bigbadtech Looks like they could be made multistage for fluid as long as they had a bypass for each stage, but probably need beefed up housing for the pressure
