KHPP260 DC Water Pump Flow 260ml/min Peristaltic Pump Liquid Transfer Pump with Gear AssemblyGear reductionHigh stabilityHigh cost performancePeristaltic pumps have many uses in industry, but their most common use Is for high purity applications. The reason these pumps are preferred for high purity applications is because the material being pumped is confined to the tube. The pump never touches the material and the material never touches the pump. This keeps the pump from contaminating the material and it also keeps the material from contaminating the pump.
