Hi,
I've never heard of an standard for this. I think you will have to design
the interface based on design details (this will include both the physical
connection specification and the communications protocol) furnished by the
pump manufacturer. Unless the manufacturer keeps it a trade secret, they
will have a manual that describes it. If it is a secret, well... You are on
your own.
