How Much Do You Learn About Vehicle Urea Pump and The Partnership Between Urea Pump And SCR

The environmental pollution brought on by auto exhaust has seriously impacted the planet, and the invention of the urea pump has wonderfully improved the environmental pollution triggered by exhaust discharges. The crucial element for regulating diesel exhaust discharges is the urea pump controller, which has actually been commonly utilized in established nations such as Europe. If you wish to buy SCR urea pump controller, you need to know more comprehensive details on it.


The urea pump is a fundamental part of the urea solution injection metering system. Its main feature is to draw out the urea service in the urea storage tank, keep a specific pressure, and then provide it to the injection unit to meet the flow as well as stress demands of the shot metering system.

The Connection Between Urea Pump And SCR
The urea pump is the core part of the SCR system, and also its performance is closely pertaining to the engine's exhaust feature. In order to make certain that the working reliability of the urea pump fulfills the working demands of the SCR system, the urea pump requires to be adjusted.

After using SCR technology, the engine's exhaust function depends to a large extent on the calibration of the urea injection system and also the loved one performance of the urea pump. Based on the standard concept of nitrogen as well as oxygen decrease, the SCR gadget makes use of a 32.5% urea liquid solution as a reducing agent, and also under the catalysis of the catalyst surface layer, the NOX in the exhaust gas is lowered to N2 as well as WATER.

The exhaust temperature level of diesel motor is generally 200-500 ° C, which generally fulfills the activity demands of the vanadium-based stimulant made use of in SCR. The NOX in the exhaust gas released by the diesel engine quickly responds with the urea liquid service to create nitrogen and water.

Urea Pump Feature
Discerning Catalytic Reduction (SCR) technology is just one of the NOX catalytic purification technologies for diesel engines that meet strict exhaust policies in the future. It has the advantages of great safety and security, reduced gas usage, as well as great sulfur resistance. Its working principle is to make use of urea remedy as well as NOX oxidation-reduction response to generate N2, which is non-toxic to human body, as well as release it right into the ambience. The urea pump pumps the urea service out of the urea storage tank and delivers the urea remedy to the nozzle with the sharing pipeline.

Functioning Principle

1. Urea storage tank 


2. Supply pump 
3. Orifice 
4. Stress chamber 
5. On-off shutoff 
6. Reverse pump 
7. Electric motor

The hydraulic and also mechanical concept of the urea pump is displayed in the figure, which is mainly composed of a motor, a supply pump, a reverse pump, an on-off shutoff, a stress chamber, and also an orifice. The pump has 2 working states, supply as well as empty. When providing fluid to the urea injection system, the motor drives the supply pump to supply the urea option from the urea storage tank to the stress chamber. A part of the urea solution is made use of for injection as well as a component is gone back to the urea tank with the orifice.

In a low temperature level environment, in order to stop pipeline blockage, the pump requires to clear the pressure chamber # The controller immediately courts that it gets in the empty state. Currently, the supply pump quits working, as well as the on-off shutoff is opened at the same time. The urea service is drawn back into the urea container.

Everyone intends to stay in even more eco-friendly city, it is a good idea to buy SCR urea pump controller can make life far better.


The mechanical and hydraulic concept of the urea pump is revealed in the number, which is mainly made up of an electric motor, a supply pump, a reverse pump, an on-off valve, a stress chamber, and also an orifice. When providing liquid to the urea shot system, the electric motor drives the supply pump to provide the urea remedy from the urea storage tank to the stress chamber. A part of the urea remedy is used for shot and a part is returned to the urea storage tank through the orifice.
