Andritz Paper Stock Pumps 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™ Andritz Pump Spare Parts Design Features:
Bearing assembly--A large diameter shaft with short overhang minimizes deflection and contributes to long bearing life. Only four through bolts are required to hold the cartridge type housing in the frame.
Liners--Easily replaceable liners are bolted, not glued, to the casing for positive attachment and ease of maintenance. Hard metal liners are completely interchangeable with pressure molded elastomers. Elastomer seal rings back all liner joints.
Casing--Casing halves of cast or ductile iron with external reinforcing ribs provide high operating pressure capabilities and an extra measure of safety.
Impeller--front and rear shrouds have pump out vanes that reduce recirculation and seal contamination. Hard metal and molded elastomer impellers are complete interchangeable. Cast in impeller threads require no inserts or nuts. High efficiency and high head designs are also available.
Throatbush--Wear is reduced and maintenance simplified by the use of tapered mating faces to allow positive accurate alignment during assembly and simple removal.
