ACP400-700.5 Centrifugal Pump Impeller is made of 1.4460 and 1.4474 duplex SS materials, and it's 5 vanes.
ACP Centrifugal Pump Design:
Impeller(230)
Accelerating the medium by charging it with energy.
Semi-open impeller with vanes on the back.
Spiral casing (102)
Guiding the medium with a favorable flow pattern, converting speed energy into pressure energy.
Pressure-sealed pump casing with delivery and suction channels.
Suction and delivery flange.
Holds the bearing housing with bearing assembly, shaft and impeller.
Pump shaft (211)
Holding the impeller, shaft seal, bearing assembly and coupling.
Transmitting the drive energy to the impeller and thus, to the medium.
Sturdily dimensioned drive shaft.
Bearings
Interface between stationary and rotating parts. Absorption of axial and radial forces.
Impeller side: Two angular contact ball bearings (321.1) with steel cage.
Drive side: One deep groove ball bearings (321.2) with steel cage.
