Introduction
A stainless steel magnetic pump is a seal-less, leak-proof centrifugal pump that uses magnetic coupling to transmit torque from the motor to the impeller, eliminating the need for mechanical shaft seals. With its stainless steel wetted parts (typically 304, 316, or 316L), it offers excellent corrosion resistance while providing complete leakage containment, making it ideal for handling hazardous, corrosive, toxic, or high-purity liquids. This article covers its working principle, key features, advantages, disadvantages, and applications.

Introduction
A magnetic gear pump is a type of positive displacement pump that uses a magnetic coupling to transmit torque from the motor to the internal gears, eliminating the need for mechanical shaft seals . This seal-less design provides complete leak-proof operation, making it ideal for handling hazardous, corrosive, toxic, or high-purity fluids where leakage could be dangerous or costly . This article covers its working principle, key features, advantages, disadvantages, and applications.

Introduction
A rotary pump is a positive displacement pump that moves fluid by rotating one or more internal elements, such as gears, lobes, screws, or vanes. Unlike centrifugal pumps, rotary pumps deliver a steady, non-pulsating flow regardless of discharge pressure, making them ideal for high-viscosity fluids and applications requiring precise flow control. This article covers the working principle, key features, advantages, disadvantages, and applications of rotary pumps.

Introduction
The jet pump is a fluid-handling device that uses the Venturi effect to move fluids without any moving parts. Driven by a high-pressure working fluid, it creates a vacuum to draw in and transport another fluid. Its simple, reliable design makes it ideal for handling challenging fluids like slurries and corrosive chemicals, though it operates at lower efficiency than mechanical pumps. This article covers its working principle, key features, advantages, disadvantages, and applications.
