Reliable Fluid Movement For Any Application

At JAECO, we manufacture and sell high-quality, long-lasting metering pumps that can be used to inject a wide array of fluids within all sorts of commercial applications. Over the years our pumps have exceeded expectations when used with anti-corrosives, liquid chlorine, reverse osmosis, effluent treatment, pivot system fluid handling, sodium hypochlorite, sodium hydroxide and sulfuric acid as well as detergents, waxes, resins and other additives. The possibilities are endless, and there are not many applications that our metering pumps cannot handle.

JAECO pumps are currently in use around the world wherever reliable fluid movement is required, including these applications:

  • Agricultural
  • Chemical
  • Government
  • Defense/Military
  • Water Treatment
  • Public Utility
  • Refining
  • Fuel Additives
  • Fiberglass Manufacturing
  • Automotive
  • Industrial Coatings
  • Vehicle Washing
  • And More

Industrial & Chemical

At JAECO we provide pumps, systems and other products to a wide variety of industries including chemical, fiberglass manufacturing, automotive, industrial coatings and vehicle washing. One example of a customized metering pump product we developed for a customer in the fiberglass manufacturing industry is a custom duplex plunger metering pump where one arm pumps the resin and the other pumps the catalyst in a predetermined mix at a very precise rate. Please contact us to learn more about pumps for industrial and chemical applications.


JAECO is a leader in the agriculture industry and has supplied thousands of metering injection pumps – both plunger and diaphragm – to inject fertilizers, pesticides, fungicides and wetting agents into irrigation and pivot systems. Our metering injection pumps are robust, flexible and available with PTO, gasoline or electric motor options.

In 2007, we developed a customized combination plunger and diaphragm injection pump called the AccuFlow that operates off of a patented heavy-duty gear reduction system. The capacity adjustment range is broader than that offered by either a diaphragm or plunger injection pump and the direction of rotation can be reversed while the metering injection pump is running which makes them ideal for use on pivot systems. Please contact us today to learn more about pumps for agricultural applications.

Government & Defense

Our pumps have enjoyed nearly 50 years of service aboard Navy ships in the treatment of waste water and fresh water. These metering pumps are a critical component of the onboard reverse osmosis system that converts seawater into fresh drinking water. Shipboard environments present some of the most difficult challenges for any rotating equipment and JAECO products continue to stand the test of time. Our Grip Seal stainless steel compression fittings have been used in a variety of start-ups.

In the early 1960s, JAECO developed a customized metering pump under contract with the U.S. Army that mimics human breathing and was created to test gas masks. This device, known as a breather metering pump, continues to be supplied exclusively by JAECO to Army installations throughout the world.

Public Utility & Water Treatment

JAECO metering pumps have been widely used in water treatment facilities to inject liquid chlorine and other chemicals to purify public drinking water. Also, our pumps are used in generating facilities to treat the effluent before the cooling water is released back into the environment. Thanks to decades of experience manufacturing pumps for a wide variety of applications, we’re a trusted resource of utilities and wastewaster treatment professionals worldwide.

Oil, Petro & Gas

At JAECO, we have many decades of experience serving the oil and gas industry. Our high-quality, reliable metering pumps are used in the traditional refinery industry to add octane, anti-corrosives, colorants and other additives into gasoline and diesel fuels. These metering pumps are also being evaluated in the evolving bio-diesel industry for similar applications. Thanks to high-quality construction and guaranteed precise operation, our pumps are a top choice in this industry. Contact us to learn more about pumps for oil, gas and refinery operations.
