RP series cryogenic pumps

Cryogenic Piston Pumps

RP series

A traditional design with a widely appreciated heritage

The RP series comprises a range of cryogenic piston pumps based on a highly appreciated traditional design.

They have a slightly inclined configuration in relation to the horizontal, proven by more than 30 years of reference in the use for filling vessels with compressed gases such as argon, nitrogen and oxygen.

Available in different models and variants, with delivery pressures up to 240 and 330 bar g respectively, RP pumps are an attractive solution in technical and economic terms for industrial and medical compressed gas filling stations.

RP Series Cryogenic Pumps

MAIN FEATURES

  • Cold part and gas/liquid separator are both housed in super-insulated vacuum jackets
  • Slight inclination to the horizontal to optimise degassing and prevent cavitation
  • Low NPSPs
  • Grease lubricated drive end
  • Low noise level

 

BENEFITS

  • Reliability
  • Reduced maintenance costs due to longer seal and piston ring life

FIELDS OF APPLICATION

  • Filling of cylinders with high-pressure compressed gases
  • Filling of buffer capacities with high-pressure gases
  • Test benches using high flow rates of high-pressure gases
  • Aerospace applications

 

PROCESS FLUIDS

Ar; N2; O2

COMPLIANCE

  • EU PED Directive
  • EU Machinery Directive
  • EU LVD Directive (for configurations including electrical wiring)
  • Compliance to EIGA Doc. 159/21
