Product information

Python XL-DA pumps are suitable for chemical dosing applications that require higher flow rates at high pressures. These pumps operate at low gas or compressed air pressures and utilise the same Merkur® air motor used in other Graco products. Graco's patented high-efficiency air valve helps minimise fugitive emissions, and gas recovery is available on certain models. The Python XL-DA pumps fluid in both directions of stroke. This ensures continuous flow operation and prevents air pockets in the pump.

  • Double-acting
    • Pumps liquid in both stroke directions - resulting in higher flow rates
    • Operation with continuous flow for better pump efficiency
    • The 2.5" pump stroke guarantees high flow rates
  • Self-priming
    • Anti-blocking system to prevent air from being trapped in the air motor and causing the pump to switch off
    • The pump can deflate itself and resume pumping without adjustments
  • Ease of maintenance
    • Simple pump design for quick seal replacement
    • Pumps are installed vertically to minimise space requirements
    • Minimum number of tools required
  • Environmentally friendly
    • Recovery of exhaust air with kit
    • Less fugitive emissions
    • 4.5" air motors are prepared for an additional kit for vapour recovery
