Which pumps are used in evaporative crystallization system

For evaporative crystallization system, the pump bearing is generally required to be Harbin P5 bearing and pressureless sintered silicon carbide mechanical seal. The specific pump types used are:

1.Stock pump,
Choose chemical pump, 316L material, double face mechanical seal, IH pump with closed impeller, or HJ pump, ij pump;
2.Forced circulation pump,
Chemical axial flow pump, fjx type, 316L material, double face mechanical seal,
3.Vacuum pump,
CS type, single seal, 2BV, open impeller;
4.Salt pump,
Chemical pump, double end mechanical seal, closed impeller, IH / HJ / ij can be used.
5.Transfer pump,
Chemical pump, double end mechanical seal, closed impeller, IH / HJ / ij can be used.
6.Condensate pump,
Centrifugal pump, single end mechanical seal, closed impeller, IH / HJ / ij can be selected.
