John Blue Company John Blue Company is celebrating 140 years as a leader in the agricultural and industrial pump market

The John Blue Piston Pump is used for applying precise, metered amounts of liquid fertilizer on planters, grain drills, side-dressing equipment and transplanters. The piston pump accurate distributes product when the crop needs it the most at planting or during various stages of growth. We offer innovative direct hydraulic drive piston pumps for variable rate and sectional shut-off in addition to

our commonly used ground drive units. With our complete line of piston pumps we also offer the John Blue Flow Divider. The flow divider when used with the piston pump accurate divides the liquid product across a wide range of application rates with accuracy. Then add our serviceable delivery line check valves to stop unwanted dripping. In addition to the piston pump line we have a full line of squeeze tube pumps that are also used for applying liquid fertilizer in the same applications described for the piston pump line. Squeeze tube pumps are ideal for low gallon applications at lower pressures. The John Blue VisaGage II is a flow monitor that is used for visually monitoring your flow rate of liquid or NH3 products. The flow monitor can be used for both spraying and fertilizer application in various number of assemblies. Now you can know your flow from your tractor cab with the Liquid Blockage Monitor System (LBMS). The magnetic sensing technology is mounted behind the VisaGage II Flow Monitors for both liquid and NH3. Identified where magnetic balls are floating in each row during application. See a visual display and hear an audible alarm on the control panel in your tractor cab. Each row with a problem will be highlighted with a flashing LED light. Our patented LBMS is available in five control panels, wired control panel, wireless iPad, Android or Amazon Kindle or the newly released ISOBUS. John Blue’s centrifugal transfer pump is designed to transfer liquid product from one source to another. We offer numerous models with various power sources and all of our pumps come with a wet seal that enables you to run the pump dry. Plus the new and improved impeller on our 3" Self-Priming Pumps offer 75 GPM more flow at 30 psi. Irrigation Injection Pumps are also available from John Blue Company. These pumps are used for accurately applying liquid fertilizers and chemicals in various types of irrigation systems such as pivot, drip, turf and nursery applications. Our irrigation pumps are available with various power sources and gallon capacity. The Anhydrous Ammonia Impellicone is a flow divider from John Blue Company that accurately divides anhydrous ammonia to multiple rows across an applicator. The design of the Impellicone allows for better control of targeted rates without over-applying Anhydrous Ammonia.
