What is Pump?

A pump is a mechanical device used to move fluids or gases from one location to another. Pumps are commonly used in a variety of industries including water treatment, chemical processing, and oil and gas production.

Different Types of Pump

Here are definitions of some common types of pumps:

1. Gear Pump: A gear pump is a type of positive displacement pump that uses gears to transfer fluids. As the gears rotate, the fluid is drawn into the pump and forced out through the discharge port.
2. Lobe Pump: A lobe pump is a type of positive displacement pump that uses rotating lobes to move fluids. As the lobes rotate, they create a vacuum that draws fluid into the pump and then compress it to discharge it out of the pump.
3. Vane Pump: A vane pump is another type of positive displacement pump that uses vanes to transfer fluids. The vanes slide in and out of slots in the pump rotor, creating chambers that trap and transfer the fluid.
4. Peristaltic Pump: A peristaltic pump is a type of positive displacement pump that uses a series of rollers to compress a flexible tube, creating a vacuum that draws fluid into the tube and then pushing it out.
5. Screw Pump: A screw pump is a type of positive displacement pump that uses an auger-like screw to transfer fluids. The screw rotates inside a cylinder, trapping and transferring fluid along its length.
6. Piston Pump: A piston pump is a type of positive displacement pump that uses a reciprocating piston to move fluids. The piston draws fluid into the pump on the upstroke and pushes it out on the downstroke.
7. Flexible Impeller Pump: A flexible impeller pump is a type of positive displacement pump that uses a flexible impeller to transfer fluids. The impeller rotates inside a casing, creating a vacuum that draws fluid in and then pushing it out.
8. Diaphragm Pump: A diaphragm pump is a type of positive displacement pump that uses a flexible diaphragm to move fluids. The diaphragm flexes back and forth, drawing fluid into the pump and then pushing it out.
