Urea-water-solution metering pump is embedded in the urea pump case. Besides used for CNHTC’s MC series engine applications, the urea solution metering pump can also be supplied to the SCR system integration manufacturer. It is directly used for after-sale service to replace similar products in the market.
Urea solution metering pump adopts gear pump structure, with DC motor driving the permanent magnetic drive shaft sleeve, magnetic coupling driving the gear pump indirectly, and its static sealing in place of dynamic sealing to have urea-water solution absolute isolated. Key parts such as pump housing are made of 316L stainless steel, which is corrosion-resistant, wear-resistant and highly reliable.
Maximum pump pressure is up to 9bar.
