What are rotary pumps?

A rotary pump is like a special kind of machine that helps move liquid from one place to another by spinning around.

Imagine you have a big cup full of juice, and you want to pour it into a smaller cup across the table. Instead of lifting the whole cup, you could use a rotary pump, which is like a tiny, spinning scoop inside a tube. As it spins, it grabs some juice and moves it along, just like how your hand might spin a straw in a drink to make bubbles.

Inside a rotary pump, there’s a part called the rotor that turns around and around. This rotor has little arms or sections that fit into another part of the pump, called the stator. As the rotor spins, it pushes liquid from one side to the other, like how your foot moves water in a puddle when you stomp.

Rotary pumps are used in many places, like in your kitchen, where they might help move milk or oil from big tanks to smaller ones. They’re strong and can handle both thick and thin liquids, just like how you can carry both syrup and water without spilling.
