12-Volt Speed Controller

John Blue Company is excited to introduce our upgraded 12-Volt Speed Controller. We have taken our customers’ ideas and incorporated them into our new design. Accurate and smooth control over a wide range of RPM’s, stand-alone gauge option, easily readable digital display, better wiring connectors, standard run/hold on 35 amp units plus much more. We consolidated greater amp capacity through better design, all at a competitive price. The 12-Volt Controller coupled with the John Blue 12-Volt Pump is ideal for low volume fertilizer applications.

The John Blue 12-Volt Controller is available in 15 and 35 amp models. A stainless steel ammonia pressure gauge is available as an option with or without a plumbing kit. The 35 amp is also available with a digital display, which keeps pressurized fertilizers or chemicals out of the cab of the tractor. The remote stainless steel sensor has a 1/4″ NPT male fitting and uses a 20 foot wiring harness. The 35 amp control comes standard with run/ hold feature, which can be wired to your implement lift switch using a whisker or proximity switch.

Centrifugal Pumps Coupled to Electric Motors

  • Patented Vac-U-Seal impeller design creates a vacuum between the impeller and mechanical seal. Lack of pressure on the seal face minimizes seal wear and results in a longer seal life.
  • Double wet seal design provides for continuous lubrication of the seal faces. This wet seal design allows the pump to be run dry for extended periods with no damage to the mechanical seal faces.
  • Closed impeller design minimizes thrust loading on the drive motor extending the life of the drive motor. Impeller wear actually increases performance.
  • Extra thick cast walls provide extra strength and extend the life of the unit due to abrasion and corrosion.
