Andritz Centrifugal Pulp and Paper Pumps Designs:
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.
Shaft seal
Depending on operating requirements, there is a choice of eight different shaft seals:
• Cartridge mechanical seal - single
• Cartridge mechanical seal - double
• Standard cartridge mechanical seal - single
• Standard cartridge mechanical seal – double
• Single standard mechanical seal

Andritz Paper Stock Pulp Pumps and Wearing Spares working advantages:

1. High efficiency and energy saving: The operating efficiency is 3-10 percentage points higher than that of ordinary pulp pumps on average, and the energy saving and consumption reduction reach 15-30%.
2. Good cavitation performance and long service life: the actual service life can be 2-3 times longer than that of ordinary pulp pumps;
3. High concentration and no clogging: the pulp concentration can reach 6%;
4. Reasonable structure and convenient maintenance: The pump head part adopts a front and rear door-opening structure. There is no need to disassemble the pipeline during maintenance. The pump can be disassembled and repaired by simply moving the motor backward.
