1.Radially split, between-bearing two-stage casing design Horizontal radially split barrel casing, double impeller in series layout. Split plane perpendicular to shaft centerline; casing owns outstand
2.Series twin-impeller hydraulic layout Two single-suction impellers mounted back-to-back, most axial force self-balanced inherently; only tiny residual axial load borne by thrust bearing.
3.High-rigidity robust rotor assembly Long rigid shaft with precision dynamic balance, compact bearing span to limit shaft deflection under high differential pressure. Standard replaceable shaft sleev
4.Full API610 standardized construction Seal chamber conforms to API682 / ISO21049, compatible with single / double mechanical seal + auxiliary flush plans. Optional oil bath, forced feed oil lubricat
5.Flexible material & medium compatibility Available in cast iron, carbon steel, stainless steel, duplex stainless steel. Suitable for clean / slightly corrosive low-viscosity process fluid, hot boile
Easy maintenance: Axially split casing, pull-out rotor without disconnecting piping or motor, short overhaul time.
Stable operation: Back-to-back impellers self-balance most axial thrust, low vibration, longer seal & bearing life.
High pressure capability: Multi-stage design delivers ultra-high head, eliminates complicated pump serial installation.
Excellent suction performance: Optional double-suction first impeller reduces NPSHR for poor inlet pressure conditions.
Wide applicability: Wide flow/head range, flexible material options for oil, petrochemical, power and corrosive media.
