2、 Strong self-absorption ability：

3、Adopt plunger cylinder built-in structure, the height is lower than the conventional vertical plunger pump. The cooling channel is built in, no leakage of circulating water, and the site is clean and tidy.

5、 intelligent control ：

Initial feeding stage: at this time, the chamber of the filter press is empty, and the material needs to be filled quickly. At this time, the hydraulic pumps with large and

Pressure filtration stage: when inside the filter press is filled with material pressure began to rise, filter press quickly out of the water, with the increase of cavity pressure, piston pump feeding pressure began to gradually rise, the piston pump automatically according to the pressure switch to run large displacement hydraulic pump, small displacement hydraulic pump stop, meet the requirements of this stage to provide the corresponding under high pressure and large flow feeding needs.
