Vertical Multistage Centrifugal Pump CDL

Shanghai Crowns Pump Manufacturing Co., Ltd. is famous for making and selling excellent water pumps. Our Vertical Multistage Centrifugal Pump CDL/CDLF is a very practical product.

These pumps are able to transport various kinds of liquids. They can handle normal tap water, and also work with different industrial liquids. You can use them in different temperature conditions, and they can manage various flow rates and pressures. The CDL type is suitable for liquids that won't cause corrosion. As for the CDLF type, it's designed for liquids that are a little bit corrosive.

The CDL/CDLF pumps are vertical and can't start by themselves. They are driven by a common electric motor. The shaft of the motor and the shaft of the pump are connected directly through a coupling. The parts that can resist pressure and the parts for the liquid to flow through are fixed between the pump head and the inlet and outlet parts by bolts. The inlet and the outlet are both at the bottom of the pump, on the same level. We can also install an intelligent protector on these pumps. This protector can effectively prevent the pump from running without liquid, having phase problems, and getting overloaded.

Work Conditions

• Liquid: The pumps are suitable for thin and clean liquids. These liquids should not burn or explode, and there should be no solid particles or fibers in them.
• Liquid Temperature: There are two temperature ranges. The regular ones can deal with liquids from - 15℃ to 70℃. And the high-temperature ones can handle liquids up to 120℃.
• Surrounding Temperature: The pumps can work in places where the temperature is up to + 40℃.
• Altitude: They can be used at altitudes of up to 1000 meters.

Product Performance

• Low Noise: The impellers of these pumps are made precisely. They have a proper shape and smooth channels for the liquid to flow. They are well balanced, so the pumps run stably. There is not much vibration and the noise is very low.
• Environmentally Friendly: We make these pumps in an environmentally friendly way. And when you use them, they also don't harm the environment.
• Safe and Hygienic: They are made of 304/316L stainless steel, which is safe and clean. This makes them suitable for tasks like water supply, in the food industry, and in the pharmaceutical industry.
• Easy to Install and Use: They are installed vertically, so they don't take up much space. The inlet and outlet are in a straight line, which is very convenient for connecting pipes. They have a flange that can rotate 360 degrees, making it really easy to connect the pipes.
• Easy to Maintain: You can replace the cartridge-type machine seal in just a few minutes. For motors larger than 7.5kW, when you need to replace the machine seal, you only need to remove the coupling, not the whole motor.

• Water Treatment: These pumps are very useful for processes like ultrafiltration, reverse osmosis, and distillation in water treatment.
• Industrial Use: They are widely used in industrial water systems, cleaning systems, high-pressure washing systems, and fire-fighting systems.
• Water Supply: They can be used to supply water to high-rise buildings or to increase the pressure in main pipelines.
• HVAC Systems: In cooling and air-conditioning systems, they help with the water circulation.
• Boiler and Condensation: They work effectively for supplying water to boilers and for recovering condensed water.
