Graco’s chemical injection pumps dispense and dose chemicals at gas and oil wellheads, as well as pipelines. They design portable, oilfield chemical injection pumps to operate at many pressures and work in harsh environments, which make them ideal for chemical injection applications.
Graco produces them in several drive types: AC, DC, and pneumatic, each offering distinct benefits depending on your requirements. In addition, to complete pumps, Graco also offers fluid and drive modules to customize your pump to your unique power supply and fluid requirements.
Electric Driven Pumps
Features: The Harrier+ controller allows for full chemical injection automation. It unlocks features and capabilities that allow you to optimize your chemical usage saving you time and money!
The controller works by controlling the injection rate via timing, cycle count, or flow control. The adaptive injection rate controls provide an accuracy of +/- 1%. The controllers use sensors along with Graco software to adjust to changes in the application such as well pressure or battery voltage. It also controls and monitors your system remotely with a cellular connection and web app. The remote connectivity allows you to monitor, control and calibrate your system via cellular or SCADA connection (Modbus). The Harrier+ controller can be made available as a standalone controller or in the power box & control panel kits.
The controller is classified for hazardous location Class 1, Divison 2, Groups A, B, C, D, T4.
The Harrier+ will provide a noticeable ROI via chemical savings, power-saving, and low cost of ownership.
Features: The Wolverine™ Hazardous Location pumps are designed to operate in applications requiring Class 1, Division 1, rated products. They have 316 SST wetted parts, plus they’re resistant to water and dust.
Flow rates up to 1,211 LPD and a pressure rating up to 10,000 PSI. Precision stroke adjustment between 1/2″ to 1″ ensures accurate injection rates. HNBR, FKM, FKM-ETP, and FFKM plunger packings and check valve seals can handle some of the most aggressive chemicals. The AC and DC operated motors are rated for use in Division 1 Hazardous (Classified) Locations per the following standards: Class 1, Div 1, Group C & D.
Features: The variable speed Wolverine pump provides continuous injection for an even dispersion of chemicals. Flow rates are adjusted between 10 and 100% by a control dial on the motor eliminating the need for a localized controller. The fluid heads are interchangeable between all Wolverine Advanced series pumps. High efficiency 12 or 24VDC brushless motors use less amperage draw than traditional brushed DC motors. It can be integrated with the Harrier+ and alternative energy sources for a fully automated, green pump.

Features: The Graco Multipoint injection system allows you to control up to 8 injection points using a single pump and controller. Set, change, and remotely monitor the individual flow rates of each injection point to help reduce the number of trips to the well site and minimize downtime. Receive alarm notifications on your phone, computer, or smart device if any disruptions in operation occur.
The Harrier+ MPI Controller features Smart Logic for solenoid failure detection. The system will continue to operate while servicing a solenoid valve to help minimize downtime. In the event of a solenoid failure, alarms will identify which one needs replacement. The controller activates one valve at a time for maximum dosing efficiencies.
The KRAKN MPI replaces up to eight chemical pumps with just one when used in conjunction with the KRAKN MPI fluid manifold. Pair it with Graco’s Harrier+ MPI control box and chemical pumps for best dosing accuracy. It is available from 2 up to 8 injection points, 316 Stainless Steel construction rated for 3000 PSI (345 Bar), using FFKM seals, and is C1D1 and GP.
Pneumatic Driven Pumps
Features: Python pumps are ideal for applications that require a pump to operate in a potentially explosive atmosphere and can run off regulated natural gas or compressed air. The Python uses half the air consumption of other pumps in the market. Plus, the Python’s extreme duty plungers, seals, and timing valve are designed for years of operation before replacement.
Pythons are offered with Chromex and Ceramic coated plungers and a standard 316 SST fluid section/wetted parts. HNBR, FKM, FKM ETP, TFEP, and FFKM plunger packings and check valve seals available.
The Python’s proprietary poppet style check valve eliminates the valve from sticking.
The Python is available in flow rates from 6 LPD to 70 LPD and injection pressures of over 10,000 PSI.
Features: The Python XL Series pumps are ideal for wells with low gas pressure – it only requires a minimum of 15 PSI to operate! The pump has a very low air/gas consumption making for increased efficiency. Up to 97% of the exhaust gas is recoverable which makes the Python XL an environmentally friendly pneumatic pump.
Fluid ends are available in 316 SS with multiple packing choices (HNBR, FKM, FKM ETP, FFKM, and TFE/P). Flow rates are available from 379 LPD to approximately 1500 LPD with a pressure range up to 1200 PSI.
Features: 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. With an option gas kit, the pump can recover its exhaust. It is self-priming and double-acting 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
The pump is capable of up to 3000 LPD and pressures up to 6000 PSI.
