GDL Vertical Multistage Centrifugal Pump
GDL series vertical multistage centrifugal pump's suction and
discharge outlets are located on the same straight line. The rotor
components are composed of shafts, impellers, impeller stop
sleeves, shaft sleeves and other parts, and the water inlet
section, middle section, and water outlet section are connected by
tightening bolts. The shaft seal adopts a mechanical seal, and is
lubricated and cooled by pressure water in the balance chamber. It
is the best pump type for the transportation of liquids such as
cold and hot water or physical and chemical properties similar to
water in major industries.
Application:
The GDL vertical multistage centrifugal pump can be used for household, irrigation, car wash, fire protection systems, air conditioning and pressure boosting in water networks.
Working Condition:
1. Used to transport clear water or liquids with physical and
chemical properties similar to clear water.
2. There should be no solid particles, no fibers, no strong
corrosiveness, and no explosion hazard in the conveying liquid.
3. The maximum liquid temperature does not exceed 120℃.
4. The maximum working pressure does not exceed 2.5MPa.
5. The power supply is 3-phase 380V, 50HZ. Voltage fluctuation is
within ±5%.
6. The ambient temperature should be lower than 40℃, and the
relative humidity should be lower than 95%.
GDL stainless steel multi-stage pump is especially suitable for boiler water supply, and can also be
widely used in pressure vessel water supply, hot water circulation,
high-rise building water supply, farmland irrigation, fire
pressurization, hydraulic washing, food, brewing, medicine,
chemical industry, and aquatic products. Various industries, such
as breeding, environmental protection, chemical process and machine
tools, are used as power equipment for water supply and drainage. 
Advantage:
1. Advanced hydraulic model: high efficiency and wide performance
range.
2. Convenient installation and maintenance: pipeline installation,
inlet and outlet can be installed in any position and direction of
the pipeline like a valve, installation and maintenance are
extremely convenient.
3. Beautiful appearance: high-quality stainless steel jacket is
used, and the appearance is beautiful.4. Less operating and maintenance costs: high-quality mechanical seals
are used, which are resistant to wear, no leakage, long service
life, low failure rate, and less operating and maintenance costs.
5. Unique components, reduce noise: unique design of water conservancy
components, good flow performance, reduce flow noise.
6. Vertical structure, small footprint.
