With over 20 years of manufacturing expertise, Shanghai Crowns Pump Manufacturing Co., Ltd. presents the CQ series magnetic drive pump (referred to as magnetic pump), a new type of centrifugal pump that applies the working principle of permanent magnet couplings. Absorbing advanced technologies, materials, and processes from domestic and international horizontal magnetic pump production, this pump successfully solves the technical challenges of easy damage to components like isolation sleeves and impellers in domestic magnetic pumps, achieving more refined performance. It features rational design, advanced craftsmanship, full sealing, no leakage, and corrosion resistance.

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.
