Flow characteristics in a volute-type centrifugal pump using large eddy
The flow characteristics in a volute-type centrifugal pump operating at design (Q d = 35 m 3 /h) and off-design (Q off = 20 m 3 /h) conditions are investigated using large eddy simulation.Numerical results indicate that separation bubbles are generated on both the pressure and suction sides of impeller blades.

Diffuser versus volute
The stator section of a centrifugal pump, after flow exits the impeller, is usually either a 'diffuser' or a 'volute'. The purpose of each of these two stator types is to efficiently diffuse velocity energy into pressure. Diffusers are characterized by a plurality of radially symmetric diffusing passageways surrounding the impeller.

Influence of different types of volutes on centrifugal aviation fuel pump
The doubles volute can also optimize the radial force under the off-design condition. The radial force of the single volute fuel pump is 100 N. The radial force of the two types of double volute fuel pump is between 10 and 20 N. The three types of volute have no obvious influence on the axial force.
