Our FE Petro™ brand diesel exhaust fluid submersible turbine pump (STP) kits come with everything you need for pumping DEF/AdBlue®. DEF STPs are offered in easy-to-order variable length complete packages or as individual kits for fixed length applications. Powered by the legendary Franklin Electric motor, our DEF STPs are built specifically for DEF applications with a host of application-specific features you won’t find on anything else out there.
Building on the field-proven DEF PMA, our DEF STPs are designed with innovative technology to suit the specific needs of DEF/AdBlue® applications. Unlike others, our entire offering is designed specifically for use in DEF.
The PMA offers a stainless steel encapsulated motor with mechanical shaft seals to protect the motor bearings, isolating the motor from product and preventing any contamination of DEF wetstock.
DEF STP kits feature stainless steel hardware and Viton® or EPDM elastomers for compatibility and longevity.
Performance is Everything
With demand for DEF varying from site to site, we’ve made it easy for you to select a single STP that is designed to perform at maximum efficiency no matter the demand of your application.
The DEF STP’S output caters for both large and small applications without excessive nozzle pressure that can make the trigger hard to squeeze and cause them to shut off prematurely.
Stainless steel hydraulic impeller provides superior performance and efficiency through the life of the STP.
We’ve Made it Simple
The complete variable length DEF STP includes everything you need in a pre-configured package for ease of ordering and ease of installation.
The full variable length kits make it easy to install in most applications while the fixed length kits provide the flexibility to install or retrofit any application.
Models for both 50 Hz and 60 Hz markets, as well as single phase and three phase applications.
Powered by Franklin Electric
Each STP is powered by a Franklin Electric centrifugal motor. As the global leader in submersible motors, Franklin Electric motors are known throughout the world as proven performers with a track record for reliability and dependability.
Motors are rated for continuous operation with bypass flow cooling to prevent motor burnout no matter how often or how long the runtime cycle.
Designed specifically to withstand station voltages and stop/start cycles to prevent motor burnout.
Pump Motor Assembly
Field-proven Franklin Electric encapsulated motor ensures longevity and impermeability to DEF seepage.
Heavy-duty shaft provides superior alignment and resistance to stress.
Double mechanical shaft seals protect the oil-filled bearing chamber from DEF seepage, assuring minimal wear and proper bearing lubrication.
Stainless steel hydraulics provide superior performance and efficiency.
EPDM jacketed power cable provides DEF compatibility and longevity.
All models are suitable for vertical installation where the pump motor is suspended off the bottom of the tank by the discharge piping.
Submersible Turbine Pump Kit
Submersible turbine pump kits come complete with variable length column pipe kit, check valve kit, bypass kit, EZ FIT pump motor assembly connection kit, and pump motor assembly.
Submersible turbine pump kits also available for locally supplied fixed length column pipe applications.
Bypass relief valve creates a continues bypass of fluid to keep the motor cool.
Check valve maintains line pressure while the pump is not in operation.
EZ FIT PMA connection makes disconnection and reconnection of the PMA quick and easy.
Each EZ FIT connection comes complete with coupler and gasket to ensure tight connection.
Each variable length submersible turbine pump kit comes complete with variable length column pipe kit (VL1 or VL2), check valve kit, bypass kit, EZ FIT pump motor assembly connection kit, and pump motor assembly (single or three phase).
Motor rating: Continuous operation with motor cooling provided by product flow and protected from dry running
Submersible Turbine Pump Kit
All stainless steel hardware and Viton® or EPDM seals
Bypass relief valve cracking pressure of 30-40 psi (2.1-2.8 bar) and 4 gpm (15 lpm) minimum flow at the discharge of all models
Non-return check valve cracking pressure of 3 psi (0.2 bar) between product piping and bypass relief valve of all models
Liquid compatibility: All models are intended for use with Diesel Exhaust Fluid (DEF). DEF is a non-flammable, non-combustible liquid that has a specific gravity of 1.09 at 68˚F (20˚C), and is made per ISO 22241-1 specifications with 32.5% urea and distilled or deionized water. As defined by ISO 22241-1, DEF is the same as AUS 32® (aqueous urea solution) and also commonly known as AdBlue®
Pump Motor Performance
DEF-PMA150A (Single Phase) and DEF-PMA150D (Three Phase)
Note: Performance is based on pumping water (1.00 specific gravity). Pressure is taken at the discharge outlet of the pump motor.
