DHB homogeneous & emulsification pump comprise 3-5 layers of stators and rotators. The alveolus of eachlayer stator and rotator is from wide to slender, let original asymmetric size material to enter pump chamberto breaking, dispersion, refinery, homogenization, emulsion step by step. They are high-efficiency compoundfine homogeneous pumps for breaking, dispersion, disaggregation, compound, refinery, homogenizationemulsion and transmission, it is also major compound homogeneous equipment in chemical workingprocedures.
