The WQ Submersible Sewage Pump is designed for the efficient transfer of wastewater and sewage from buildings, industrial sites, and other areas prone to flooding. With a fully submersible design, this pump operates directly in the fluid it is tasked to move, making it ideal for applications where space is limited or pumps must be submerged. It features corrosion-resistant materials and reliable sealing, ensuring long-term durability and uninterrupted performance in harsh environments.

The JYWQ Submersible Sewage Pump with Agitator is a high-end wastewater treatment equipment developed for complex industrial and municipal sewage environments. Integrated with an innovative agitator design, it ensures solid materials and sediments remain suspended through continuous agitation, effectively preventing pipeline blockages, significantly enhancing sewage transfer efficiency, and reducing maintenance frequency. Its advanced structural design fundamentally prevents large particles from settling at the pump’s bottom, achieving a dual breakthrough in energy efficiency and reliability through hydrodynamics optimization.

Shanghai Crowns Pump Manufacturing Co., Ltd. excels in designing, producing, and selling various water pumps. Our cast iron horizontal pipeline pump meets ISO standards, ensuring high performance and reliability. This series offers robust engineering, making it an ideal choice for efficient and reliable water pump solutions.

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.
