Centrifugal Pump for Froth?
Centrifugal Pump for Froth?
(OP)
Centrifugal pumps are'nt the best for moving froth, but we're stuck with the equipment. Any suggestions? There's a debate about high speed vs low speed impellers, large vs small pump sizes, inducers, etc. Basically horizontal, all metal pumps, submerged inlet feeding off the side of the sump, VFD controls, different sizes.
Any practical advice from the experts? - THANKS!

Since you go by sprintcar, is this a race engine dry sump application? If so, I thought the scavenging pumps were positive displacement pumps, typically of a spur gear design.

The sprint motor is dry sump. I've used both gear and gerotor pumps for engine oil - both seem to work, although the gerotor seems to pull better crankcase vacumn. There's a couple designs w/ air separators, but we just put it back to the tank tangentially and allow for the extra volume. The oil we run (Royal Purple) seems to defroth pretty quickly. I am open to any suggestions!!
