1. Product overview：

　　GDL type vertical multi-stage pipeline centrifugal pump is a new generation of products designed and manufactured by SEALOCEAN based on excellent foreign pump types, combined with user requirements and fire-fighting standards, and based on JB/TQ6435-92 standard.

The suction and discharge ports of the water pump are located in the same straight line. The rotor parts are composed of shafts, impellers, impeller sleeves, bushings and other parts, and the inlet section, middle section, and outlet section are connected with tensioning bolts. The shaft seal is mechanically sealed and lubricated and cooled with pressure water from the balance chamber. It is the best pump type for conveying liquids such as hot and cold water or liquids with physical and chemical properties similar to water in major industries.

2. Scope of application：

　　GDL type vertical multi-stage pipeline centrifugal pumps are widely used in the circulation and pressurization of hot and cold water in high-pressure operating systems, the parallel water supply of multiple pumps in high-rise buildings, fire fighting, boiler water supply and cooling water systems, and the delivery of various flushing fluids.

3. Product features：

　　1. GDL type vertical multi-stage pipeline centrifugal pump has advanced hydraulic model: high efficiency and wide performance range.

　　2. Easy installation and maintenance: ducted installation, import and export can be installed at any position and in any direction of the pipeline like a valve, which is extremely convenient for installation and maintenance.

　　3. Beautiful appearance: the use of high-quality stainless steel jacket, beautiful appearance.

　　4. Less operating and maintenance costs: the use of high-quality mechanical seals, wear-resistant, no leakage, long service life, low failure rate, and less operating and maintenance costs.

　　5. Unique components, reduce noise: Unique hydraulic component design, good overcurrent performance, minimize flow noise.

　　6. Vertical structure, small footprint.
