CQ Engineering Plastic Magnetic Pump (Live Connection)

Product Overview

The CQF engineering plastic magnetic drive pump is a new type of pump that utilizes the working principle of permanent magnet couplings to transmit torque without contact. When the prime mover drives the outer magnetic rotor to rotate, the inner magnetic rotor is synchronously driven through magnetic field interaction. Since the inner magnetic rotor is integrated with the impeller, the impeller is driven without direct contact. As the liquid is enclosed within a stationary isolation sleeve, the magnetic drive pump is fully sealed and leak-free, thereby eliminating the unavoidable issues of leakage, dripping, and spillage associated with mechanical seal centrifugal pumps. In industries such as petroleum, chemical, pharmaceutical, and electronics, an increasing number of manufacturers require leak-free processes for the media they transport and urgently seek ideal pump types. Our company's CQF series magnetic drive pumps incorporate advanced technologies, new materials, and innovative processes from high-level magnetic pump production, successfully overcoming the technical challenges of easily damaged components like the isolation sleeve and impeller found in current market magnetic pumps.

Applications

The flow-passing components of the CQF series engineering plastic magnetic drive pumps are made of reinforced polypropylene (PP) engineering plastic. They are widely used in petroleum, chemical, pharmaceutical, electroplating, environmental protection, water treatment, national defense, and other sectors. These pumps are ideal for transporting flammable, explosive, toxic, and precious liquids, making them an excellent choice for creating leak-free and pollution-free workshop environments. Operating temperature range: -20°C to 100°C.

Leak-Proof Design

By replacing dynamic seals with static seals and utilizing magnetic coupling for indirect drive, the pump eliminates dripping issues and prevents contamination of the usage area. It is an industrial pump that杜绝es leakage, spillage, dripping, and running in chemical processes, eliminates environmental pollution, and enables the creation of "leak-free workshops" and "leak-free factories" for safe and civilized production.

Operating Principle

The magnetic drive pump consists of three parts: the pump, the magnetic drive, and the electric motor. The key component, the magnetic drive, comprises an outer magnetic rotor, an inner magnetic rotor, and a non-magnetic isolation sleeve. When the motor drives the outer magnetic rotor to rotate, the magnetic field penetrates the air gap and non-magnetic materials, driving the inner magnetic rotor connected to the impeller to rotate synchronously. This achieves non-contact power transmission, converting dynamic sealing into static sealing.

Advantages

Compared to centrifugal pumps using mechanical seals or packing seals, magnetic drive pumps offer the following advantages:

1. The pump shaft changes from dynamic sealing to enclosed static sealing, preventing medium leakage.

2. No independent lubrication or cooling water is required, reducing energy consumption.

3. The drive changes from coupling transmission to synchronous dragging, eliminating contact and friction. This results in low power consumption, high efficiency, and damping vibration reduction, minimizing the impact of motor vibration on the pump and the effect of pump cavitation vibration on the motor.

4. In case of overload, the inner and outer magnetic rotors slip relative to each other, protecting the motor and the pump.
