Technical Information
The information below is for reference. Final order data is subject to the technical agreement and product nameplate.
I. Product Overview
The GDL series vertical multistage pipeline pump is a new generation of vertical multistage centrifugal pumps, designed and manufactured based on advanced pump models while incorporating practical application requirements and relevant fire-fighting standards.
Designed and manufactured in accordance with the JB/TQ6435-92 standard, these pumps are suitable for transporting cold and hot clean water, as well as liquids with physical and chemical properties similar to water.
The pump features an inline suction and discharge configuration with a vertical pipeline structure, ensuring compact dimensions and ease of installation.
The rotor assembly consists of a shaft, impellers, impeller spacers, and shaft sleeves. 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.
The company employs computer-aided design (CAD) and optimization technologies, combined with comprehensive testing systems and advanced manufacturing processes, to ensure stable performance and reliable operation.
II. Scope of Application
These products are widely used in the following areas:
- High-rise building water supply systems
- Pipeline booster systems
- Fire-fighting water supply systems
- Boiler feed water systems
- Cooling circulation systems
- Industrial cleaning systems
- Hot and cold water circulation systems
- Parallel pump water supply systems
Suitable for transporting clean water and liquids with physical and chemical properties similar to water.
