9. There are two options: stainless steel impeller liquid ring pump and common material + atmospheric ejector.
10. Kfl 2bw4 water ring vacuum pump unit has more perfect and reliable configuration.
3、 Technical parameters
Pumping rate: it depends on the supporting vacuum pump
Vacuum degree: it depends on the supporting vacuum pump
4、 Model representation
For example, 2bw4 353-0bl4: 2bw4 is the series code of the complete set of vacuum pump unit dedicated to vacuum pumping of condenser; 353-0 is the supporting vacuum pump, and the specification is the improved 2BE1 353-0; B refers to the material of the pump, which is ordinary material (the stainless steel time number of impeller or other flow passage parts is e); L refers to wearing the injector (without the injector, the time number is k); 4 is that the shaft seal mode of the pump is the water supply mode in the packing (the code of the water supply mode in the single end mechanical seal is 2).
5、 Application field
Kfl 2bw4 liquid ring vacuum pump unit can be applied to condenser vacuum pumping, flue gas desulfurization, fly ash transportation and water chamber vacuum pump in power industry.
