Product information

Python XL-DA series pumps are designed for chemical metering applications that require higher flows at high pressures. These pumps operate at low gas or air pressures and use the same Merkur® air motor found in other Graco products. Graco's patented high-efficiency air valve helps minimise fugitive emissions, and gas recovery is possible on certain models. The Python XL-DA pumps liquid in both directions of stroke. This ensures continuous flow operation and prevents air from being trapped in the pump.

  • Double-acting
    • Pumps liquid in both directions of stroke – resulting in higher flow rates
    • Continuous flow operation for better pump efficiency
    • 2.5" pump stroke ensures high flow rates
  • Self-priming
    • anti-clogging system to prevent air from being trapped in the air motor and causing the pump to shut down
    • The pump can clear itself of air and resume pumping without adjustment
  • Easy to maintain
    • Simple pump design for quick seal changes
    • Pumps are installed vertically to minimise space requirements
    • Minimum number of tools required
  • Environmentally friendly
    • Exhaust air recovery kit
    • Reduced fugitive emissions
    • 4.5" air motors are prepared for an add-on kit for gas recovery
