Structure Feature

>Axial Split Casing:

The casing is designed with an axial split structure, divided into two parts: the pump body and the pump cover. They are connected with a large flange at the center. The pump’s weight is mainly concentrated on the pump body and pump cover, resulting in high rigidity of the pump casing. Large-sized pump models use a double volute casing structure to reduce radial forces, ensuring stable operation and long maintenance intervals.

>Suction and Discharge Pipes:

The suction and discharge pipes are located in the lower half of the casing.This allows for easy inspection, disassembly, and installation of the entire rotor parts without disconnecting the inlet and outlet piping. This design provides the advantages of easy maintenance, short repair times, and low maintenance costs.

>Double-suction lmpeller:

The impeller is of a double-suction, closed design, capable of automatically balancing a significant portion of axial forces. Excellent blade hydraulic designe ensures high pump efficiency, low cavitation margin, a wide operating range,and stable operation.

>Rigid shaft:

The rigid shaft design is reliable and suitable for harsh operating conditions,ensuring trouble-free operation at the first critical speed. The shorter bearing span and rigid shaft minimize deflection in all operating environments, ensuring stable pump operation.

>Heavy-Duty Bearings:

Conventional pump models use deep groove ball roller wear-resistant bearings on the drive end to absorb radial forces, while non-drive ends use back-to-back mounted angular contact ball bearings to absorb residual axial forces. These bearings are designed for harsh operating conditions, have a long design life.and offer high reliability. This results in the pump having low overall noise, low vibration levels, and other advantages.
