GDL Vertical Inline Centrifugal Pump

I. Product Overview

The GDL series vertical multistage in-line centrifugal pump is a new-generation product designed and manufactured by our company based on excellent overseas pump models, user requirements, relevant fire-fighting standards, and the JB/TQ6435-92 standard.

The pump's suction and discharge ports are aligned on the same axis. The rotor assembly consists of a shaft, impellers, impeller spacers, shaft sleeves, and other components; the inlet, middle, and discharge sections are connected by tie bolts. A mechanical seal is used for the shaft, lubricated and cooled by pressurized water from the balance chamber. It is an ideal pump for transporting hot and cold water, or other liquids with physical and chemical properties similar to water, across various industries.

Our products are designed and optimized using computer-aided technology. Backed by strong technical expertise, extensive manufacturing experience, and comprehensive testing facilities, we ensure stable and reliable product quality.

II. Scope of Application

Widely used for the circulation and pressurization of clean hot and cold water in high-pressure systems, parallel water supply for high-rise buildings, fire-fighting systems, boiler feed water and cooling water systems, and the transport of various flushing fluids.

III. Product Features

1. Advanced Hydraulic Model: High operating efficiency and a wide performance range.

2. Convenient Installation and Maintenance: In-line piping design allows the inlet and discharge ports to be installed at any position or orientation along the pipeline—much like a valve—making installation and maintenance extremely convenient.
