About Great Plains Industries

Great Plains Industries (GPI) is a family-owned, engineering-driven manufacturer with more than five decades of experience designing and building fluid transfer and measurement equipment. Founded in 1968 in Wichita, Kansas by engineer Charlie Peer, the company grew from a small agricultural innovation into a globally recognized name in fuel, oil, and chemical handling technology.

The story began when Peer recognized a need in the agriculture sector for reliable, portable transfer solutions. That entrepreneurial spirit has never faded — today, Great Plains Industries operates out of a nearly 180,000-square-foot headquarters in northeast Wichita, where the majority of its products are engineered and assembled in the USA.

GPI, GPRO, and FLOMEC: A Family of Innovation

Great Plains Industries is home to three trusted product brands, each serving a distinct segment of the fluid handling market:

• GPI® — The flagship line, with a long legacy of fuel, oil, and chemical transfer pumps and meters designed for agricultural, automotive, and construction applications. GPI pumps are known for being lightweight, corrosion-resistant, and factory-tested for consistent performance.
• GPRO® — A professional-grade lineup of fuel transfer pumps and meters built exclusively for demanding commercial applications where a more robust design is required.
• FLOMEC® — Acquired in 2013, FLOMEC brings precision industrial flow measurement to the portfolio, offering oval gear, turbine, ultrasonic, mag, and impeller flow meters for industries ranging from chemicals and food & beverage to oil & gas.

Industries Served

Great Plains Industries products are trusted across a remarkably broad range of sectors. Whether it is dispensing diesel on a farm, measuring chemical flow in a manufacturing plant, or fueling heavy equipment on a construction site, GPI solutions are engineered to handle the job. Core markets include agriculture, automotive, construction, mining, oil and gas, and industrial manufacturing.

The company further expanded its global reach with the acquisition of Trimec Industries in Sydney, Australia — now operating as Great Plains Industries Australia — adding oval gear, insertion, and impeller flow meter expertise with distribution across Asian and European markets.

Built on Engineering and Reliability

What sets Great Plains Industries apart is its roots in engineering. Products are designed with real-world durability in mind: corrosion-resistant materials, factory-tested assemblies, and field-serviceable components like quick-change vane kits that let operators perform maintenance without specialized tools. The company's reputation for strong customer support reflects its family-owned culture — one where relationships with distributors and end users are taken as seriously as the quality of the products themselves.

From portable hand pumps ideal for transferring motor oils and fuels on the go, to sophisticated industrial flow meters used in automated batching systems, Great Plains Industries offers a comprehensive range of fluid handling solutions built to last.
