Its not stable unless you stabilize it, there are stabilizers available.
HPLV pumps work best, I don't know if the screw type is best, it might be compressing the product.
if the cream is spitting from the nozzle thats a sign the air is being forced out from the cream.
Maybe you need a piston type pump vs screw.
The cream obviously has to be very cold to combat friction temps.
You would do well to talk to a food process engineer who deals with fluid dynamics.
I can put you in touch with a very good one, he's retired now.
