1. Centrifugal Pumps
Centrifugal pumps are one of the most widely used water pumps. Their key features include high flow rate, high head, high efficiency, smooth operation, low noise, and easy maintenance. They are suitable for a wide range of applications, including industry, agriculture, construction, public utilities, and residential sectors. Centrifugal pumps use centrifugal force to draw liquid into an inlet and accelerate it, then convert the high-speed liquid into high-pressure energy for flow out the outlet.
2. Self-Priming Pumps
Self-priming pumps are self-priming centrifugal pumps. They use their own air valve to self-prime the liquid, eliminating the need for pre-priming. They are suitable for pumping volatile liquids or applications where water is difficult to prime. Key features of self-priming pumps include compact structure, easy maintenance, high self-priming efficiency, and reduced number of starts. Self-priming pumps are suitable for pumping clear water or liquids that are chemically similar to water.
3. Submersible Pumps
Submersible pumps are pumps used for underwater pumping. Their key features include compact structure, easy installation, flexible operation, and low noise. Submersible pumps are widely used in industry, agriculture, construction, and residential sectors, such as drainage pumps, deep well pumps, and centrifugal sewage pumps. The basic operating principle of a submersible pump is to draw in liquid and discharge it through the rotation of an impeller driven by an electric motor. It is suitable for conveying both clean water and wastewater containing solid particles.
4. Vortex Pumps
A vortex pump, also known as a micropump, is a type of pump suitable for conveying low-head, high-flow liquids. Its key features include high flow rates, compact size, low noise, and long service life. Vortex pumps are suitable for conveying low-head, high-flow liquids such as compressed air, lubricating oil, and circulating water in both industrial and civilian applications. The operating principle of a vortex pump is to convert gas or liquid into a vortex through the rotating impeller, generating high kinetic energy. The vortex is then converted into fluid pressure for discharge.
