There are various types of pumps used in various industrial and commercial applications. Each type of pump has a unique design and function. Following are some common types of pumps and their functions:
Centrifugal Pumps: These pumps use centrifugal force to move fluid through the system. They are suitable for transferring fluids with high flow rates and low to medium pressures. Centrifugal pumps are widely used in applications such as clean water delivery, waste water treatment, cooling systems, and the chemical industry.
Crank Pumps: Crank pumps, also known as piston pumps or diaphragm pumps, use the movement of a piston or diaphragm to generate pressure and move fluid. They are often used in applications where high pressure is required, such as chemical processes, high pressure cleaning, and pesticide spraying.
Submersible Pumps: These pumps are designed to work in liquids, usually water. They are placed below the surface of the liquid to be pumped, such as a well or pond, and are used to pump water to the surface. Submersible pumps are often used in agricultural irrigation, oil wells, drinking water supply, and sewage applications.
Vacuum Pump: A vacuum pump is used to remove air or gas from an enclosed space to create a low pressure or vacuum. They are important in a variety of applications, including semiconductor production, food processing, refining, and pharmaceutical processes.
Peristaltic Pumps: Peristaltic pumps move fluid through the hose by periodically squeezing or pushing it. They are ideal for dealing with fluids that are sensitive to contamination because no part of the pump comes into contact with the fluid being pumped. Typical applications include vial fillers, medical infusion pumps, and chromatography analysis.
External Rotor Pumps: These pumps have two rotating rotors inside the shell, creating a volume-changing chamber to move fluid. They are used in applications where positive displacement is required, such as the transfer of heavy materials, silo filling, and pumping fluids of varying consistencies.
Circulation Pumps: Circulation pumps, also known as pumping pumps or transfer pumps, are used to move fluids from one location to another in a closed system. They are often used in heating, cooling, and water circulation systems.
