Structural Features

Pump Casing

Inlet and outlet ports are of the same diameter and aligned on the same centerline, allowing valve-like installation in pipelines.

Compact and aesthetically designed, occupying minimal space.

Impeller

Hydraulically optimized for Grade 1 energy efficiency, ensuring high efficiency and energy savings.

Axial thrust balanced through balance holes + rear wear ring design.

Securely fastened to the shaft via an impeller nut to prevent loosening.

Pump Cover

Designed to withstand the same pressure as the pump casing, ensuring structural strength and rigidity.

Wear rings between the casing, cover, and impeller strictly comply with API 610 hardness and clearance requirements, enhancing efficiency, stability, and service life while reducing part replacement frequency.

Shaft Sealing

Seal chamber conforms to API 682 standards, compatible with

Cartridge-type single mechanical seal

Double mechanical seal

Tandem mechanical seal

· Configurable with standard auxiliary systems; packing seal also available.

Bearing Housing

· Independent bearing pedestal with splash ring oil lubrication (standard design).

 · Equipped with a constant-level oiler for automatic oil level compensation.
