Centrifugal pump is the most widely used pump that has different types. Each of the centrifugal pumps has different characteristics and applications, and these characteristics of the centrifugal pump depend on its structure and internal components such as the impeller. The pump impeller is responsible for circulating the fluid inside its chamber and is used in most types of dynamic pumps. Centrifugal pump impeller plays an important role in the type of use of the pump and what kind of impeller is used and with what design is important.
Types of Centrifugal Pump Pump
Closed propeller
In the closed propeller, the propeller blades are closed on both sides by a disk-like plate. Due to its structure, this type of propeller can clog when pumping fluids with impurity, and for this reason, it is used in the applications of transferring and pumping clean and low-viscosity fluids such as water. Pumps with a closed impeller have the ability to move a large volume of clean fluid with high pressure, including pumps with a closed impeller, we can refer to all types of household water pumps and floor pumps.
Semi-open propeller
The structure of the semi-open propeller is designed in such a way that one side of its blades is surrounded by a disk-like plate and the other side is open. Semi-open impellers can be used for fluids with higher viscosity than closed impellers. Steel Leo ABK semi-open impeller pump is one of the pumps that are used to transfer liquids that contain small solid particles.
Open propeller
The blades of the open propeller type are open on both sides and for the possibility of fluid contact between the blades, in addition to the blades of the blades, there are two types Closed and semi-open impeller can flow fluids with higher viscosity and also containing solid particles. Open impeller is used in sludge pumps. To buy a sludge pump and to know about its availability and price, you can contact the experts of Kalasanati Pump.
Types of Centrifugal Pump Pumps in terms of blades
Vortex propeller
The vortex propeller looks similar to the semi-open propeller, but one side of its blades is closed, and of course the shape of its blades is different. Because there is more space in the vortex impeller between its outer environment and the pump body, a vortex flow is established in this space and solid particles in the fluid are prevented from coming into contact with the impeller itself. Vortex impeller is usually used for moving liquids containing small amounts of solids and with lower viscosity, such as sewage.
Screw propeller
As the name of this type of propeller indicates, the screw propeller has a screw shape and due to its twisting structure, it can be used to transport fluids with viscosity be used above.
Cutter propeller
The cutter propeller has a sharp edge at the end of its blades, and for this reason, it is used for liquids with more solid particles. This type of impeller cuts the fluid containing solids at the pump inlet and by crushing them into smaller particles, it prevents the pump from clogging and makes the pumping process easier.
