RPS series piston pumps for CO2 and N2O

Piston Pumps

RPS series

A traditional design with a legacy of reliability and wide appreciation

The RPS series includes a range of piston pumps specifically for CO2 and N2O. They are based on a popular traditional design, with a configuration slightly inclined to the horizontal, proven by over 30 years of reference in the use for filling containers with compressed fluids such as carbon dioxide and nitrous oxide.

Available in different models and variants, with delivery pressures up to 100 bar g, RPS pumps are an attractive solution for carbon dioxide and nitrous oxide filling stations, for both industrial and medical applications.
