ZCQ Magnetic Drive Pump

I. Product Overview

The ZCQ series magnetic drive centrifugal pump (hereinafter referred to as the self-priming magnetic pump) is a new product that applies the working principle of permanent magnet couplings to centrifugal pumps. Featuring a rational design and advanced manufacturing technology, it is fully sealed, leak-free, and corrosion-resistant, with performance matching the advanced standards of similar international products. The pump is compact, aesthetically pleasing, small in size, quiet, reliable in operation, and easy to maintain. It is widely used in sectors such as chemicals, pharmaceuticals, petroleum, electroplating, food processing, film processing, scientific research, and national defense for pumping acids, alkalis, oils, rare or precious liquids, plating solutions, and volatile liquids, as well as for integration with circulating water systems. It is an ideal choice, in particular, for handling flammable, explosive, or volatile liquids.

II. Working Principle

This pump utilizes an external-mixing axial flow structure. The pump body consists of components including a suction chamber, liquid storage chamber, volute, return port, and gas-liquid separation chamber. Upon startup, centrifugal force causes the impeller to agitate the residual liquid in the suction chamber with the air in the inlet pipeline, creating a gas-liquid mixture. This mixture enters the gas-liquid separation chamber via the volute; as the flow velocity decreases, gas and liquid separate. The air is discharged through the pump outlet, while the liquid returns to the pump body through the return port. After repeated cycles, the air in the inlet pipeline is fully evacuated, creating a vacuum within the pump and enabling self-priming. III. Key Pump Performance Parameters:
