Injection Pumps

Graco’s chemical injection pumps dispense and dose chemicals at gas and oil well-heads, as well as pipelines. We design our portable, oilfield chemical injection pumps to operate at many pressures and work in harsh environments, which make them ideal for chemical injection applications. We produce them in several drive types: AC, DC and pneumatic, each offering distinctive benefits depending on your requirements. In addition to our complete pumps, we also offer fluid and drive modules to customise your pump to your unique power supply and fluid requirements.



Easily Configure your Injection Pump

Easily customise your fluid sections and the drive ends to work with many aggressive oilfield chemicals. The pump gives you precise control over corrosion inhibitors and more.

Control Precise Injection Rates

You’ll achieve total control over your pump’s feed rates, which gives you more flexibility when planning chemical dosing.

Long-Lasting Fluid Packings

Graco pumps are engineered with industrial-grade fluid seals and packings that are rated to deliver years of productive operation.
