Applications

● Suitable for use with clean water and liquids that are not chemically aggressive towards the materials from which the pump is made.
● As a result of their reliability and the fact that they are easy to use, these pumps are widely used in domestic and civil applications such as the distribution of water in combination with small and medium sized pressure sets, for transferring liquids and for the irrigation of gardens and allotments. The pump should be installed in an enclosed environment, or at least sheltered from inclement weather.

Working principle of clean water centrifugal pump

Under normal circumstances, liquid can only automatically flow from high to low, and from high-pressure equipment to low-pressure equipment. If the liquid at a lower place is sent to a higher place and the liquid in low-pressure equipment is sent to high-pressure equipment, a certain amount of energy must be provided to these liquids to achieve this goal. We usually call the equipment that can provide energy to liquid a clean water centrifugal pump.

The driver drives the impeller to rotate through the clean water centrifugal pump shaft to generate centrifugal force. Under the action of centrifugal force, the liquid is thrown toward the impeller outlet along the blade flow path, and the liquid is collected through the volute and sent to the discharge pipe. The liquid obtains energy from the impeller, which increases both pressure energy and speed energy, and relies on this energy to transport the liquid to the work site. While the liquid is thrown toward the impeller outlet, a low-pressure area is formed at the center of the impeller inlet, and a pressure difference is generated between the liquid in the suction tank and the center of the impeller. Under the action of this pressure difference, the liquid in the suction tank It continuously enters the impeller through the suction pipeline and the suction chamber of the pump.
