A peripheral pump is a type of centrifugal pump that is designed to handle liquids with low to medium viscosity. The main difference between a Vortex Peripheral pump and a traditional centrifugal pump is the way that it generates flow. In a traditional centrifugal pump, flow is generated by the impeller spinning within the volute, which is a casing that surrounds the impeller. EDWIN PUMP provides a big power range from 370w to 1500w. Max flow can be 100L/Min and max head can be 70M. Inlet and outlet sizes are 1" and 1.5". The vortex in the volute is created by the shape of the volute and the way that it is positioned in relation to the impeller. The volute has a unique shape that is designed to cause the liquid to flow in a circular pattern. As the liquid moves in this circular pattern, it creates a vortex that pulls the liquid from the inlet and pushes it toward the outlet of the pump. This creates a low-pressure area in the center of the vortex, which causes the liquid to be drawn into the pump. This is because the vortex in the volute is able to generate flow more efficiently than the impeller in a traditional centrifugal pump. The vortex also helps to keep the liquid in suspension, which reduces the risk of the liquid separating or becoming aerated. EDWIN PUMP uses a two-pole induction motor for centrifugal pumps. Insulation class B, protection IP44, and continuous service S1. Because the vortex generates flow more efficiently than an impeller, the pump requires less energy to produce the same flow rate. This can result in significant energy savings over time, especially in applications where the pump is used for long periods of time. Anti-block system is important for long service life. So EDWIN PUMP has a brass or SS insert equipped between the pump body and the support of peripheral pumps. It can reduce the abrasion of the impeller and avoid pump clogging when the pump is not used for a long time.
