Product Overview

The CWB Magnetic Vortex Chemical Pump (hereinafter referred to as “Magnetic Vortex Pump”) is a new type of pump that applies the principle of permanent magnetic coupling to centrifugal pumps. It features a fully sealed structure, zero leakage, low flow, high head, and excellent corrosion resistance, reaching the advanced level of similar foreign products. By replacing dynamic seals with static seals, all wetted parts are completely enclosed, eliminating the inherent leakage problems (such as dripping or seepage) associated with mechanical seals in traditional pumps. The pump primarily uses corrosion-resistant, high-strength engineering plastics, alumina ceramics, and stainless steel to provide excellent corrosion resistance while ensuring the conveyed medium remains uncontaminated.

Model Designation

CWB Magnetic Vortex Chemical Pump type

Key Features

  • Zero-Leakage Operation: Static seals replace dynamic seals to ensure leak-free transfer of the medium.

  • Excellent Corrosion Resistance: Made from high-strength engineering plastics, alumina ceramics, and stainless steel to offer superior corrosion resistance.

  • Low Flow, High Head Design: Especially suitable for low-flow, high-head applications, with speeds typically less than 40.

  • Self-Lubricating Circulation Path: Extends the life of the sleeve (sliding) bearings.

  • Dedicated Cooling Circuit: Removes the vortex heat generated in the magnetic coupling, supporting stable operation.

Engineering Overview

The CWB pump uses a permanent magnetic drive configuration to transmit torque without mechanical contact. The static seals fully enclose the wetted ends, ensuring truly leak-free transfer. The material system, combining corrosion-resistant engineering plastics, alumina ceramics, and stainless steel, balances chemical compatibility and operational reliability, making the pump ideal for low-flow, high-head services.
