Tobee® Alternative Andritz S series single-stage process centrifugal pumps are available with closed, semi-open or open impellers. These wear-resistant pumps are suitable for working with a wide range of media. Depending on the type of impeller, they can transport contaminated liquids with amount of solids up to 8%. They are used as process pumps in paper, chemical, sugar, energy, food industries, water, sewage treatment, drainage or other systems.
ANDRITZ S series centrifugal pumps are available with closed, semi-open or open impellers in a highly wear-resistant design. The S series pumps are suitable for conveying many different media. Depending on the impeller design, they can convey slightly contaminated and contaminated media with some solids and content up to consistencies up to 8%. Thus, operating as processes pumps, they cover a wide range of applications in the pulp and paper, mining, offshore, power, food, and chemical industry. Additionally, ANDRITZ single-stage centrifugal pumps can also be used in water supply, waste water treatment, desalination plants, and irrigation as well as drainage. A modular system ensures high availability, enables the use of proven components and reduces the number of spare parts to be held in stock. For more information on our single-stage centrifugal pumps from the ACP and S series please have a look at our brochures in the sidebar or contact us directly.
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.
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
• Tandem mechanical seal
• Stuffing box packing
• Dynamic shaft seal
