Single vs. Double Suction: All of the impellers shown in the specific speed table above are of the single-suction design. This means that there is a single portion of the impeller that is designed to take in water. There are also impellers designed to take suction from both sides of the impeller. A drawing of this type of impeller can be seen ...
An impeller is a rotating component equipped with vanes or blades used in turbomachinery (e. g. centrifugal pumps).Flow deflection at the impeller vanes allows mechanical power (energy at the vanes) to be converted into pump power output..

Description: Horizontal, high-pressure barrel-type pump with radial impellers, single- and double-entry, multistage, with flanges / weld end nozzles to DIN and ANSI. Applications Handling of feed water and condensate in power stations andindustrial facilities, generation of pressurized
• Overhung Impeller Type: The impeller is mounted on the end of a shaft which is "overhung" from its bearing supports. Example: –Close Coupled pumps where the impeller is mounted directly on the motor shaft –Separately coupled or frame mounted where the impeller is mounted on a separate pump shaft supported by its own bearings.
Horizontal Split Case pumps are a types of centrifugal pump type has a single double suction impeller supported between bearings. Casing is split horizontally for maintenance. Suction and discharge flanges are opposed to each other. Double suction impeller gives better NPSH and lower axial thrust.
Helical Impeller Helical Impeller (2 Outer Flights) (1 Inner Flight, 2 Outer Flights ) Helical impellers are used primarily in applications involving very viscous materials. They operate with minimal clearance at the vessel wall and provide axial flow at low speed. Their construction can be single or double outer
Impeller – Types of Impellers. ... Double-suction. A double-suction impeller allows liquid to enter the center of the impeller blades from both sides simultaneously. This reduces forces exerted on the shaft. The output pressure slightly changes according to the design used. The blades may be open or closed.
The closed impeller has both a back and front wall for maximum strength. They are used in large pumps with high efficiencies and low NPSHR. They can operate in suspended-solids service without clogging but will exhibit high wear rates. The closed-impeller type is the most widely used type of impeller for centrifugal pumps handling clear liquids.
When a casing contains only one revolving impeller, it is called a single-stage pump. When a casing contains two or more revolving impellers, it is called a double- or multi-stage pump. In biology, many different types of chemical and biomechanical pumps have evolved; biomimicry is sometimes used in developing new types of mechanical pumps.
Centrifugal Fan Blade Types. ... On single inlet fans, the drive side is the side opposite the fan inlet. On double inlet fans with drives on both sides, the drive side should be on the same side as the higher-powered drive unit. ... Impeller overhung on prime mover base mounted or integrally directly connected.
A double-entry impeller is an impeller with a suction entry on both sides. A double-entry impeller is employed to reduce the axial thrust and the NPSHr value. See Figs. 6, 18 Impeller
An impeller is a rotating component of a centrifugal pump which transfers energy from the motor that drives the pump to the fluid being pumped by accelerating the fluid outwards from the center of rotation. The velocity achieved by the impeller transfers into pressure when the outward movement of the fluid is confined by the pump casing.
Mixing 101: Flow Patterns & Impellers Mixing Flow Patterns & Impeller Types. In our article on 4 Impeller Types and Their Applications, we provided an overview on the most common types of impellers used in industrial mixing.Now we'll go into more detail about each impeller type and their influences on the mixing process.
impeller between the impeller vanes. If an object gets caught on the leading edge of one of the vanes, it will slide along the backswept shape towards the perimeter of the inlet. Stage 2. The solid object will slide along the tip of the impeller vane inside the relief groove. The guide pin in the insert ring will push all types of solids away from

Pump Impeller Types. Impellers of pumps are classified based on the number of points that the liquid can enter the impeller and also on the amount of webbing between the impeller blades. Impellers can be either single suction or double-suction. A single-suction impeller allows liquid to enter the center of the blades from only one direction.
