Features and Benefits

Wilden® GPS Series pumps, equipped with the Pro-Flo® SHIFT Air Distribution System (ADS) and available in bolted metal construction, are certified by the Canadian Standards Association (CSA) to be powered by natural gas and maintain a safe, reliable operation. They are perfect for oil and gas operations where compressed air is not readily accessible but where natural gas is plentiful.

  • NPT or BSPT threaded inlet/discharge liquid connections (GPS220)
  • DIN or ANSI flanged inlet/discharge liquid connections (GPS230) that don't require welding or nipple attachment
  • GPS Series pumps utilize the Wilden Pro-Flo SHIFT ADS
    • Helps plants save valuable natural gas
    • Pro-Flo SHIFT uses 60% less natural gas, without hindering performance
    • Greater flow - more gallons pumped per SCFM
