Produced by Shanghai Crowns Pump Manufacturing Co., Ltd. with over 20 years of manufacturing experience, the mechanical diaphragm metering pump is a type of diaphragm pump where the flexural deformation of the diaphragm is directly driven by mechanical force. It is generally suitable for conveying liquids without solid particles, with a temperature range of -15℃~85℃ and a viscosity range of 0.3mm²/s~2000mm²/s. The flow rate can be steplessly adjusted within the range of 0-100%. The product features static seal without leakage at the hydraulic end, simple structure, low maintenance cost, and excellent cost performance. It is applicable to industries such as environmental protection, water treatment, pharmaceuticals, papermaking, and new materials, and can be used for conveying slurries and hazardous chemicals.
