Overview

GDL vertical multi-stage pipeline pumps are widely used for the circulation and pressurization of cold and hot water in high-pressure operating systems, parallel water supply of multiple pumps in high-rise buildings, fire protection, boiler feedwater and cooling water systems, and the transportation of various flushing liquids.

Product Details

1、 Product Overview:

The GDL vertical multi-stage pipeline centrifugal pump is a new generation product designed and manufactured by our company based on excellent pump types abroad, combined with user requirements and relevant fire safety standards, and according to JB/TQ6435-92 standards.

The suction and discharge ports of the water pump are located on the same straight line. The rotor components consist of shafts, impellers, impeller sleeves, shaft sleeves, and other parts. The inlet, middle, and outlet sections are connected by tension bolts. The shaft seal adopts mechanical seal and is lubricated and cooled with pressure water from the balance chamber. It is a pump type used for transporting hot and cold water or liquids with physical and chemical properties similar to water in various industries.

2、 Application scope of GDL vertical multi-stage pipeline pump:

Widely used in the circulation and pressurization of hot and cold clean water in high-pressure operating systems, parallel water supply of multiple pumps in high-rise buildings, fire protection, boiler water supply and cooling water systems, and the transportation of various flushing liquids.
