I am looking for a pump vendor which meets my design specification:
Process fluid: Liquid CO2
Temp: -50oC
suction prsesure: 7 barg
discharge pressure: 70 barg
volumetric flowrate (at T and P): 60 L/hr.

I tried to find local vendors in South Korea but no luck with this low temperature and small flowrate.

Assume you have exhausted all pump companies that come up on google etc?

It is a capital mistake to theorise before one has data. Insensibly one begins to twist facts to suit theories, instead of theories to suit facts. (Sherlock Holmes - A Scandal in Bohemia.)
 
You could look at LEWA pumps, PTFE diaphragm is rated to -50°C, but they have options for -70°C as well. Low flow metering pumps rated for 70 bar.
 
Thankyou DMHCE, I will write an email to them.
 
If you're really hard up, you can take an off the shelf pump and equip it with seals that tolerate your temperatures.
 
Thankyou TugboatEng for the suggestion. However, I contacted LEWA as suggested by DMHCE and already sent the datasheet for quotation.
