This machine is a high efficiency and energy saving product based on the original ZGS series vertical high consistency hydraulic pulper. With the unique upper drive design and bottom suspension technology, the combined power is reduced by more than 50% on the premise of guaranteeing the original ZGS high efficiency and rapid pulping characteristics, and the obvious energy saving effect is achieved. At the same time, the bottom bearingless chamber, no packing seal, no maintenance, no leakage of water worries. The uploading device adopts unique water-cooling decelerator and universal coupling, with low failure rate and easy maintenance.
