DHG series adjustable gap grinding pump comprise 3-5layers 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 grind,dispersion, refinery, homogenization step by step. The gap between rotor and stator can be adjustedby external hand wheel according to medium particel size and technology requirement,adjusting range is0.03mm-7mm. Besides this, the gap also can be adjusted when rotor or stator has a litle womn.so that remain effect while long-term production,upgrade the production efficiency and reduce production cost.

These series products are widely used in petrochemical,refinery chemistry,viscose fiber, environmental protection,papermaking,foods processing and so on.
