Pump for liquid AC charging

(OP)
Hello guys
I'm working on a test bench where i need to charge a refrigerant into the ac unit. I m trying to charge it with liquid and at high flow (100g/s).
are there pumps used specifically for refrigerant (R134a)?
Thank you.

RE: Pump for liquid AC charging

Canned motor pumps. Check GRUNDFOS or HERMETIC.

Thank you for your help.
I've checked in HERMITIC, they have these kind of pump except that they work at high flow (12-50 m^3/h), I'm looking for smaller flow range ( 0-0.4 m^3/h) (0.1 l/s).
