Diesel Engine Emissions Control
Diesel Engine Emission Control
The use of Selective Catalytic Reduction (SCR) to remove NOx from the exhaust of diesel engines
How It’s Used
A gear pump is used to inject Urea into the exhaust of the diesel engine. The Urea combines with the exhaust and converts the NOx to nitrogen and water in the catalytic converter
Smooth flow, Freeze Resistant, Rugged
SCR modules for diesel emissions control
Urea (30% Ammonia in water)
10 to 100 mL/min (0.16 to 1.6 USG/hr)
<116 psi (<8.0 bar)
To meet diesel engine manufacturers are turning to Selective Catalytic Reduction (SCR). SCR is an emissions control system that injects liquid urea into the catalytic converter in the exhaust stream of engines. The urea converts the NOx into harmless nitrogen and water.
Gear pumps are used to deliver urea under pressure to a nozzle in the exhaust stream. Gear pumps provide the smooth flow and precise flow control required for this application.
Micropump pump used to inject urea into the exhaust stream.
FLOW RATE: 10 to 100 mL/min (0.16 to 1.6 USG/hr)
Our Series GA and GB pumps offer flow rates from 8.5 to 6400 mL/min (0.13 to 102 USG/hr)
MAX DIFFERENTIAL PRESSURE: 8.0 bar (116 psi)
Our Series GB pumps support differential pressure up to 8.6 bar (125 psi)
PRECISE FLOW CONTROL
Our pumps offer smooth, pulseless flow with an integrated drive offering fast responses to changing flow requirements
Mag-drive gear pumps minimize leaks by eliminating dynamic shaft seals (no shafts penetrate the pump chamber wall)
Survive Harsh Environments
Our drives and pumps were built to survive the harsh conditions found in vehicular markets. Our pumps are designed to tolerate freezing liquids and the electronic components in our drives are all automotive rated.
Simplified system design, low maintenance and long life are a winning cost-of-ownership combination for our mag-drive gear pumps
