Electro Mechanical Pressure Compensator?

Electro Mechanical Pressure Compensator?

Electro Mechanical Pressure Compensator?

(OP)
Seeking some knowledge/suggestions:

I basically need a Pressure Compensator, which will be sited in a dry space (hub) in a sub sea application.

But I don't really want to use the ACTUAL pressure of the sea on compensator, as that would mean additional penetrations, which I need to avoid, OR siting the Pressure Compensator outboard, which is not an option either.

I DO however, have a pressure signal (from a sensor) available in the hub.

So.... is there an off the shelf product, that will supply oil to a cavity (non circulating, very low leak rate) at a pressure determined by my pressure sensor (+0.5bar).

Needs to be 24v, and happy to spend it's life rotating around a horizontal axis!

I've been looking into automatic oilers (the type that is fitted to big trucks) but need some alternatives.

I know I could design this system myself, but for cost and time reasons, it needs to be (pretty much) off the shelf.

here's hoping

TIA

James.
