Python® XL-DA Pneumatically Operated Pumps

Ideal for Applications requiring higher flows at higher pressure


Python XL-DA series pumps are suitable for chemical injection applications that require higher flows at high pressures. These pumps operate on low gas or compressed air pressures and utilize the same Merkur® air motor used on other Graco products. The Graco patented high-efficiency air valve helps minimize fugitive emissions and gas recovery can be achieved on specific models. The Python XL-DA pumps fluid in both stroke directions which provides continuous flow operation and prevents the pump from air locking.

Double Acting

  • Pumps fluid in both directions of the stroke for increased flows
  • Provides continuous flow operation for better
    pump efficiencies

Self Priming

  • Anti-locking so air cannot get trapped inside air motor and stall pump
  • Pump can free itself of air and resume pumping without any adjustments

Ease of Serviceability

  • Simple pump design for quick seals replacement
  • Pumps are installed vertically for a reduced footprint
  • Minimum number of tools required

Environmentally friendly

  • Recoverable exhaust gas with kit
  • Less fugitive emissions
  • 4.5” air motors come ready for a gas recovery add-on kit
