Product details
GDL vertical multi-stage centrifugal pump
1、 GDL vertical multi-stage centrifugal pump product overview:
GDL type vertical multi-stage pipeline centrifugal pumpIt is a new generation product designed and manufactured by our company based on excellent pump models from abroad, combined with user requirements and relevant fire safety standards, and in accordance with 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 the best pump type 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 centrifugal 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.

__________________________________________________________________
Tip 1: When placing an order, please specify the specific technical parameters, operating conditions, and characteristics of the medium used, so that we can choose the most suitable product for you.
Tip 2: After long-term operation of the pump, if the noise and vibration of the unit increase due to mechanical wear, it should be stopped for inspection and replaced if necessary
Damaged parts (mechanical seals, impellers, bearings, shaft sleeves, etc.), the overhaul period of the unit is generally one year.
Tip 3: Oil the bearings every 500 hours of pump operation.
Tip 4: Due to the use of a flexible shaft, this pump has lower stability and lifespan compared to DL type multi-stage pumps. It is recommended for use as a stabilizer in daily life or in non long-term or uninterrupted water supply situations.
