About Diesel Exhaust Fluid (DEF)
The Fill-Rite DEF pump is designed to pump AUS32 (Aqueous Urea Solution 32.5%), better known as Diesel Exhaust Fluid, or “DEF”.
AUS32 is used by modern diesel engines which are equipped with an SCR (Selective Catalytic Reduction) system. DEF never comes into contact with the fuel;
the common misconception is that it is an additive. DEF is carried on-board the vehicle in its own storage tank. It is injected into the exhaust gases as a post
combustion process through an SCR where it breaks harmful NOx (Nitrous Oxide) emissions down into mostly Nitrogen and Oxygen.
Because the specific purity of the AUS32 solution is critical to the catalytic reaction, the Fill-Rite DEF pump is designed to maintain the integrity by using
components made of materials that will not taint or alter the solutions chemical structure.
After initial assembly and installation, flush the entire dispensing system by pumping 1 - 2 gallons of DEF through it. This
purges the system of air, and ensures any impurities that may have been in the system are washed out. Dispose of the Diesel
Exhaust Fluid used to flush the system using approved Diesel Exhaust Fluid handling procedures; do not return the fluid to the
drum or tote, or use it in a vehicle.
Symptom Cause Cure
Pump will not prime
Suction line problem Check for leaks or restrictions in suction line
Jammed check valve Inspect inlet and piston valves
Fluid incompatibility Consult fluid mfg. for compatibility with wetted materials
Low capacity
Excessive dirt in nozzle screen Remove and clean screen
Suction line problem Check for leaks in suction line
Pump fluid leakage
Dirty seal Clean O-ring and seat area
Bad seal Replace seal
Gasket leakage Tighten covers and joints
Fluid incompatibility Consult fluid manufacturer for compatibility with wetted materials
Troubleshooting: FR20V and FRHP32V Hand Pumps
Troubleshooting: FRAP32V Air Operated Pump
Symptom Cause Cure
Pump air piston does not
operate
Air pressure is too low; minimum
recommended air pressure is 30 psi (2 bar)
Increase air supply pressure to between 30 psi and 100 psi (2 bar to 6 bar).
Piston frozen in place (frost on air
cylinder)*
Close air inlet valve and allow piston & cylinder to thaw (see * note below)
Low capacity
Low air pressure, or pressure has dropped
below 30 psi (2 bar)
Close & re-open air inlet valve
Piston frozen (see above) If stalling occurs regularly, adjust the regulator to increase the air pressure
* After periods of extensive use, usually with a hose kit, the air piston on the FRAP32V air pump may freeze because of excess moisture in the air supply line. If this
condition persists, install a filter, filter / lubricator, or a water separator to reduce moisture content in the air supply to the pump.
