The model 1951 Plunger pump has been introduced by CAT Pumps (USA) specifically to pump liquid carbon dioxide, with the growth of CO2 use in refrigeration systems. The 1951 pump has been developed to increase intervals between servicing and eliminate the need for extra cooling or an additional booster pump. The pump head is manufactured from UNS 31603 stainless steel for liquid and process compatibility, strength and corrosion resistance. Pump models are available to generate from 20bar up to 350 bar and flow rates between 1 and 120litres/minute.
