Especially for the pumping equipment using the S pendulum valve, the skirt valve and the gate valve as the distribution valves, in the reversing process of the distribution valves, as the conveying pipelines are communicated with the hopper through the distribution valves, the materials can flow back under the action of pipeline pressure, and part of high-concentration materials flow back to the hopper through the distribution valves, so that the pumping volumetric efficiency is reduced, and even the high-pressure materials flowing back can cause great pressure impact on the hopper and feeding equipment, and the safety of the pumping equipment is influenced.

Because the seals of the distribution valves of the S-shaped swing valve, the skirt valve, the gate valve and other pumping equipment are directly contacted with the materials and are all dynamic seals, the bearing pressure of the distribution valves is small, so that the pumping pressure of the pumping equipment equipped with the distribution valves is too small, and when the conveying distance is long or the concentration of the materials in a conveying pipeline is high, the conveying system is difficult to overcome large conveying resistance to effectively convey the materials. Therefore, the pumping equipment using the S pendulum valve, the skirt valve and the gate valve has the problems of easy material backflow and poor reliability and safety.

As described above, the conventional high-concentration material delivery pump is still difficult to adapt to the high-efficiency, long-distance and high-pressure delivery of high-concentration paste materials due to its inherent defects, and has many disadvantages such as complicated structure, poor reliability and stability, and poor safety.
