Agri-Inject

Agri-Inject was founded in 1983 in Yuma, Colorado. The company is led by CEO Erik Tribelhorn, who has guided its product development and manufacturing strategy over multiple decades. As a private Colorado company, it has not publicly disclosed additional executive leadership or outside directors.

Agri-Inject manufactures fluid-injection pumps that precisely meter fertilizers, chemicals, and soil amendments into pressurized irrigation systems. Its products serve center-pivot, drip, and sprinkler irrigation across row crops, orchards, and specialty agriculture. The company is particularly known for its blue chemical injection pumps, which have become a common sight on farms using chemigation and fertigation practices in the western United States.

Agri-Inject is an operating manufacturing company, not a family office or investment vehicle. Public records show no separate fund structure, outside capital raises, or investment activity. The firm appears to operate as a closely held, self-funded manufacturer with no disclosed family-office or investment-arm overlay.

Agri-Inject sells through a network of agricultural equipment dealers and irrigation supply distributors. The firm does not operate a direct-to-consumer e-commerce channel. Its dealer network covers major US agricultural regions, with additional export activity into Latin America and the Middle East, where its pumps support large-scale irrigation projects in water-scarce environments.

Unlike major irrigation OEMs such as Lindsay or Valmont, which offer injection pumps as one component within a broad product catalog, Agri-Inject builds only fluid-injection equipment. This single-category focus, sustained for over 40 years from a manufacturing base in rural Colorado, gives it deep specialization in chemical metering and injection consistency that multi-line competitors rarely match in the aftermarket. The firm's machines are designed for field serviceability by growers rather than dealership-only maintenance.
