Radial split suction impeller design, excellent cavitation performance,first Impeller can adopt double suction structure to improve cavitation performance；Cavity dimensions fully meet API682 standards and can be equipped with various seal plan and cooling plan；Precise balance calculation.The axial force can be controled,pump running stability；Multistream diffuser design,effectively balance the hydraulic radial force of the rotor effectively；Ball radial and 7300 series thrust bearings are standard. Pressure lubricated sleeve/pivot shoe bearings are optional；Seal chamber meets API682 requirements； The high standardization design not only reduces inventory costs but also achieves the maximum interchangeability of components, thereby reducing the operating costs of the equipment throughout its life cycle.
