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 WQK Cutting Sewage Pump is a specialized submersible solution for wastewater containing large solids and fibrous materials. Its integrated cutting mechanism efficiently breaks down rags, plastic debris, and organic waste into smaller particles, reducing clog risks and ensuring smooth operation. Ideal for hospitals, residential complexes, and food processing industries, this pump tackles common blockage challenges—from sanitary products to vegetable scraps—with durable, submersible design. It integrates seamlessly into sewage systems, minimizing downtime and maintenance while handling tough wastewater flows.

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.
