Product Overview

The CWB Vortex Magnetic Drive Pump (hereafter referred to as the magnetic vortex pump) is a centrifugal pump designed based on the principle of permanent magnetic coupling. It uses a static seal concept, ensuring the pump operates in a completely sealed state with zero leakage, high head, low flow, and excellent corrosion resistance. This pump is particularly suitable for applications that require high safety standards and centralized control, and is widely used for handling high-safety-demand media while avoiding the risk of leakage.

CWB Vortex Magnetic Pump – High Head Corrosion Resistant Pump type

Key Features

  1. Permanent Magnetic Drive Design
    The magnetic drive system achieves complete sealing and zero leakage operation, eliminating the need for traditional mechanical seals.

  2. Low Power, Low Flow Hydraulic Characteristics
    Operates efficiently under low flow and high head conditions, with high energy efficiency suitable for various needs.

  3. Compact Design
    The pump is compact, occupying minimal space, making it suitable for environments with space constraints. It is easy to install and use.

  4. Cantilever Impeller Design
    The cantilever impeller reduces radial forces, improving stability and efficiency, making it adaptable to different working conditions.

  5. Self-Lubricating and Independent Cooling System
    It integrates a self-lubricating circulation path and a dedicated cooling circuit to extend the lifespan of sliding bearings and reduce maintenance requirements.

Engineering Overview

The CWB magnetic vortex pump replaces traditional mechanical seals with permanent magnetic coupling, completely isolating the drive end from the pumped medium. All wetted parts operate within a fully enclosed system, fundamentally eliminating leakage issues such as dripping or seepage associated with mechanical seals. This design makes it especially suitable for applications where leakage is intolerable, and it can operate reliably in high head and low flow environments.
