China OEM Andritz Interchangeable Housing Cover Spares Manufacturer

Tobee™ Andritz Pump Spare Parts namely the pump parts have direct connection with slurry, are very crucial to the service life of slurry pumps. The wet parts, include impeller, liner, throatbush, frame plate liner insert, casing, etc., are very easily worn-out components because they work under longtime impact of abrassive and corrosive slurries in the high speed. For the long service life of pump parts, the material plays an important role here.

Andritz Paper Pumps and Spares Design Features:

• Impeller - Adopting full open type impeller with large channel design by precision casting, No. of vanes is 3-6 vanes,This configuration can reduce the axial force, And in the transporting, it will not generate bubbles, non-clog impeller channel,Improving the pulp concentration.
• Volute casing - Adopting single stage vortex casing, big size, Casing is designed as duoble casing structure for reducing radial force and axis deviation.
• Materials - various mateials of Wetted parts are available, Such as Cast iron,SS304,SS316L,Duplex stainless steel etc
• Shaft seal - Mechanical seals and packing seal can be used as per requested
• Severe application - Excellently suited for transporting media containing solids (e.g. for pulp, paper, or effluent applications)

Tobee® manufacture a range of replacement parts including impellers(2 vanes, 3 vanes, 6 vanes, 8 vanes), casings, casing cover, front lining, rear lining, stuffing box body, shaft etc which for Andritz S series pumps, ACP series pumps, FP series pumps, VP series pumps, CP series pumps etc

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
