2 micro gear pumps that produce about 32 onces at 12 volts and self prime I havent tested the fluid raising distance yet but they are strong!
I have these in stock and will be selling them for 35.00$ each plus shipping.
On the left is a very small not much bigger than a dime not including the barbs and comes with a motor like the other larger one.
The other is about 7 mm thick and about the size of a quarter.
Both work on 6 to 12 volts and draw very little power.
The motors can be replaced with other ones as desired as long as the shaft is the same diamiter.
Great for mini hydraulics like masts or even larger systems and ballast aplications.
