DESIGN FEATURES & ADVANTAGES
New high-capacity series of horizontally mounted, axially split, multistage, between bearings pumps with double volute casing
Excellent suction capability due to double-suction first stage NPSH impeller
Back-to-back impellers providing rotor axial balance and low wear of rotating elements
Symmetrical casing parts and centreline-located feet ensure uniform temperature expansion of the casing with high-temperature liquids
Specially designed pump stages, wear rings and bushings provide uniform pressure drop per mm throughout the pump width for uniform distribution of normal wear of the elements for increased reliability
High-strength compact size casing with single row easy accessible bolting simplifies the pump maintenance operations
Extra heavy-duty rigid shaft with minimum deflection in operation to extend lifetime of bearings and mechanical seals
SHAFT SEAL
Seal chamber, being complaint with API 610 / ISO 13709 requirements, is designed to fit API 682 / ISO 21049 compliant seals of a cartridge type and provides necessary space for tandem and double mechanical seals installation.
