Red Jacket® CoreDEF™ Submersible Turbine Pump


The Red Jacket® CoreDEF™ Submersible Turbine Pumps are a revolutionary solution that sets a higher standard in the optimization of diesel exhaust fluid (DEF) pumping infrastructure. The CoreDEF™ STP is the entirely customizable DEF pump, designed for a complete range of light to heavy duty submersible DEF applications.

Various motor sizes, Quick Set® variable lengths, and the only adjustable pressure relief offering on the market, make the CoreDEF pump a flexible solution that can be tailored to maximize value, while controlling cost.

With included pre-assembly and factory leak testing, the CoreDEF submersible DEF pump cuts out the stress and time of installation and get you pumping sooner.

Model Portfolio for Varying Applications:

  • The CoreDEF Series Portfolio holds the perfect motor size for your site.

Factory Leak Tested – Diesel Exhaust Fluid is extremely hard to contain and even harder to clean up:

  • CoreDEF submersible DEF pumps are factory-tested to prevent any possibility of leaks in the field.
  • Using a competitive pump may allow leaks and crystallization, seriously complicating serviceability.

Adjustable Pressure Relief Option – Enables the user to adjust line pressure between 20-45 PSI, making for painless post-installation flow rate tuning:

  • Optimize operation with any dispenser.
  • Avoid excessive nozzle squeeze.
  • Prevent nozzle spit back.

Product Compatibility:

  • Designed for DEF consisting of 32.5% urea and 67.5% de-ionized water.
