The GDL series vertical multi-stage pipeline 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. All of our products are designed and optimized using computers. Our company has strong technical strength, rich production experience, and comprehensive testing methods to ensure stable and reliable product quality. 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.

1. Strong discharge capacity, unobstructed, and capable of effectively passing solid particles with a diameter of 30 to 80 millimeters.
2. The tearing mechanism can tear, cut, and smoothly discharge fibrous substances without the need for a filter screen on the pump.
3. Reasonable design, small matching motor power, significant energy-saving effect.
4. By using mechanical sealing materials, the pump can operate safely and continuously for more than 8000 hours.
5. Compact structure, easy to move, simple installation, no need to build a pump room, reducing project costs.
6. It can be equipped with a fully automatic protection control box to effectively protect the product from leakage, water leakage, and overload, improving the safety and reliability of the product.
