Corrosion prevention, freezing, and plugging.

Graco’s pneumatic chemical injection pumps meet and exceed the oil and gas industry standards for performance and endurance. Our chemical pumps are designed to work in environments that require explosion proof equipment and run off natural gas or compressed air. Other features include:

  • Lowest out-of-pocket cost
  • Easy to operate
  • Designed for durability

Python® Pumps

Python pumps are ideal for applications that require a pump to operate in hazardous locations and can run off regulated natural gas or compressed air. These pumps have the lowest out-of-pocket cost, are easy to operate and can use half the air consumption of many other pumps on the market. Plus, the Python’s extreme duty plungers, seals and timing valve are designed for years of operation before replacement.

Graco Python pneumatic chemical injection pumps are the right solution for injecting chemicals at well sites and pipelines to protect them from corrosion, plugging and freezing. Python pumps offer features critical to the oil and gas industry:

  • Ideal for applications that require a pump to operate in an explosion proof environment
  • These chemical pumps run on regulated natural gas or compressed air
  • Uses half the air consumption of other pumps in the market
  • Easy to operate
  • Lowest out of pocket cost
  • Extreme duty plungers, seals, and timing valve are designed for up to two years of operation before replacement

Ease of Serviceability

  • Easy access to the pump plunger and packing
  • Cartridge style seal in the timing valve for quick and easy repair
  • Plunger packing can be replaced in 10 minutes or less

Highest technology timing valve on the market

  • Low air/gas consumption for increased efficiency
  • Pump cycle rate remains constant regardless of system back pressure
  • Robust and simple design
    • Adjustable fluid packing can last up to 25 times longer than non-adjustable seals
    • Pythons are offered with Chromex and Ceramic coated plungers
    • 316 SST fluid section/wetted parts
    • HNBR, FKM, FKM ETP, TFEP and FFKM plunger packings and check valve seals
    • Proprietary poppet style check valve eliminates valve from sticking
  • Standards
    • CE and ATEX approved.

Python® XL Pumps

Python XL series pumps are ideal for wells with low gas pressure. Capable of operating up to 12,000 psi, the pumps are easy to operate and include an air motor with the same proven technology that Graco offers in other product lines. Plus the Python XL’s extreme duty plungers (Chromex™ and ceramic coated), seals and air valves are designed for years of operation before replacement.

Ease of serviceability

  • Modular air valve design
  • Removable pilot valve
  • Pump lowers are interchangeable with other Python XL models
  • Plunger packing can be replaced in 10 minutes or less

Highest technology air motor on the market

  • Only requires a minimum of 15 psi to operate pump
  • Low air/gas consumption for increased efficiency
  • Muffler provides low operation noise levels
  • Proven Graco® Merkur® air motor technology

Robust and simple design

  • 316 SST fluid section/wetted parts
  • Three stroke adjustment positions
  • HNBR, FKM, FKM ETP, FFKM, and TFE/P
  • plunger, packing, and check valve seals

Environmentally friendly

  • 97% recoverable exhaust gas
  • Reduced fugitive methane emissions

Python® XL-DA Pumps

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
  • 2.5 inch pump stroke for high flow rates

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

Python® XL-DA25

The Python XL-DA25 is a product line extension to the current Python XL-DA product family so it uses the same double-acting technology and can achieve nearly double the flow rate of a similar single-acting pump. The Python XL-DA25 comes with a 2.5 in. pump stroke covering a wide range of flow rates. These pumps operate on low gas or compressed air pressures and utilize the same Merkur® air motor used on other Graco products. The wetted parts are all 316 stainless steel and the air motor comes with a Graco proprietary coating suitable for off-shore applications.

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