JQB 7stars pneumatic piston-type slurry pump series (referred to as: pneumatic slurry pumps, pneumatic pumps, slurry pumps, also known as: pneumatic pump barrel plug pumps, explosion-proof plug pneumatic piston pump barrel, barrel pump, pneumatic piston pump, pneumatic piston pump, pneumatic pump concentration, pneumatic reciprocating pump, Pneumatic plastic pump, pump pneumatic pump, pneumatic pump explosion-proof stainless steel, leather spray pumps, high-viscosity slurry pump, pneumatic pump, slurry pump to fight) is widely used in artificial leather, leather shift membrane, calendar leather, printing and dyeing, pharmaceutical, coatings, chemicals, textiles, painting, spraying, film-plated aluminum, color-coated steel tile, ink, Japan, and sanitation, mining, plastics additives, intermediates, PU foam, PVC, organic solvents such areas as trade, low, medium and high viscosity liquid carrier material. Applicable to media of high viscosity (VIS) ≤ 12 million CPS/25 ℃ chemical pulp and other raw materials, the pump with explosion-proof, anti-precipitation, resistant, durable, low-noise, energy saving, small size, light weight, easy to operation, stability and good function, is an ideal equipment for mobile transmission. Qixing JQB type slurry pump pneumatic products are developed to introduce advanced technology from abroad, the working principle is the role of pressure difference, so that the piston running up and down, expected to lead the Pistons led off and played the role of reference materials. Adjustments to the pneumatic pump slurry flow of working gas pressure to control and aerodynamic flow pump feeding regulation. Combination of sensor switch can automate the process of work.
