ZCQF Magnetic Drive Pump

I. Product Overview

The ZCQF series self-priming magnetic drive pump (hereinafter referred to as the magnetic pump) is a new product utilizing the working principle of permanent magnet couplings. It features a rational design and advanced manufacturing technology, offering a fully sealed, leak-free, and corrosion-resistant performance that rivals advanced international equivalents.

II. Product Features

1. The magnetic self-priming pump replaces dynamic seals with static seals, keeping the pump's flow-path components completely sealed. This eliminates the leakage issues (spraying, dripping, or seeping) inherent in the mechanical seals of other pumps. Materials such as corrosion-resistant, high-strength reinforced polypropylene, PTFE alloys, silicon nitride, carbon-graphite, and corundum ceramics are used in construction. Additionally, a stainless steel mounting bracket is employed, sparing customers the hassle of frequent bracket replacements caused by atmospheric corrosion.

2. It combines the functions of the CQF magnetic drive pump with self-priming capabilities, eliminating the need for a foot valve or priming water. It offers excellent self-priming performance with short priming times and high operating efficiency, and it can run dry without liquid. With a self-priming lift of 4 meters, it provides superior corrosion resistance and ensures the pumped medium remains uncontaminated.

III. Product Applications

These magnetic pumps feature a compact structure, attractive appearance, small footprint, low noise, reliable operation, and ease of maintenance and use. They are widely used in sectors such as chemicals, pharmaceuticals, petroleum, electroplating, food processing, film processing, scientific research, and national defense. Applications include pumping acids, alkalis, oils, rare or precious liquids, toxic substances, and volatile fluids, as well as serving as components for circulating water systems and filtration equipment. They are particularly ideal for pumping leak-prone, flammable, or explosive liquids, especially when paired with an explosion-proof motor.

IV. Working Principle

This pump utilizes an external-mixing axial return-flow casing structure. The pump body consists of components including a suction chamber, liquid storage chamber, volute, return port, and gas-liquid separation chamber. After the pump starts, under the action of centrifugal force, the residual liquid in the suction chamber and the air in the inlet pipeline are agitated by the impeller into an air-liquid mixture. This mixture enters the gas-liquid separation chamber via the volute casing; as the flow velocity decreases, the air and liquid separate. The air is discharged through the pump outlet, while the liquid returns to the pump body through the recirculation port. Through repeated cycling, the air in the inlet pipeline is completely evacuated, creating a vacuum within the pump and enabling self-priming operation.
