S valve filling pump can be used for coarse aggregate tailings, tailings dry row, high concentration mud, slurry and chemical sludge and other materials pumping. According to the characteristics of the slurry, the specially designed internal structure reduces the flow resistance of the slurry, and the slurry is sucked into the concrete cylinder to the maximum during the reversing process. The volumetric efficiency (processing capacity) of the filling pump is greatly improved, and the maximum filling capacity of a single device reaches 400m.3/h。

2. The industrial filling pump adopts a dual pump dual circuit fully hydraulic control system (patented by Heyu), and the automatic pumping process is completely controlled by hydraulic pressure without any electro-hydraulic conversion control link, with extremely high reliability.
3. The dual pump system of industrial filling pump has the following advantages over the single pump system: the pumping and S-pipe swing functions are driven by independent oil pumps, the oil pump can withstand half of the number of directional shocks, and the service life of the main oil pump is longer than that of the single pump system; At the same time, the pumping and distribution oil circuits do not interfere with each other, and compared to a single pump system, the peak hydraulic shock can be reduced by 80%.
