What type of Self-priming centrifugal pump is this ?

Hi pumping gurus

no luck with trying to source this type of pump...

has anyone come across this type of self-priming
centrifugal pump.

it has a main impeller & a second impeller which
does the priming.

video is attached of the pump.

That's a liquid ring vacuum pump paired with a straight centrifugal pump.

And only self-priming if the liquid ring vavuum pump is primed or can be primed during start up.
Nearly 50 years ago, I drew-up and prepared patent papers for a very similar design, the bearing pedestal included the liquid-ring vacuum pump, I never applied for the patent based on advice from others who considered and I agreed that a seperate stand-alone vacuum was probably a better option.

However back to the OP, wouldn't be surprised if this isn't some kind of subtle advertising - let's see what develops.

Gilkes is a manufacturer of this type of pump.

ok TugboatEng... thanks for the lead

these pumps from Gilkes seem to be for
marine or boat applications. flows are
not very large.

do they make larger flow pump sizes for
industrial applications.

Many self-priming pumps around, letting us know what the application is a better approach.
