Light Vertical Multistage Centrifugal Pump

Product Information

The light vertical multistage centrifugal pump from DV/DVS/DVL series is ideal for the transportation of low viscosity, non-flammable, and explosive vaporized liquids without any solids or fibers. It finds extensive usage in high-rise building water supply and drainage, water filtration and transmission from plants, pipeline pressurization, and other similar applications. Besides, this centrifugal pump also acts as a supportive system for equipment like cooling water circulation, boiler water supply, water treatment systems, and more. The pump's versatility and efficiency make it a reliable choice for various industrial and commercial settings.

Features

The light vertical multistage centrifugal pump By using a mechanical seal, this pump can eliminate all leakage and prevent any negative impact on its performance. Not only does this increase efficiency, but it also helps to protect the environment from pollution. Furthermore, all components of the pump that come into contact with water are made of stainless steel AISI304. This not only looks great, but also ensures that the water quality remains pristine. Thanks to computer modeling and a stainless steel impeller, the flow of the pump is incredibly smooth and efficient, with a hydraulic efficiency that is 15% higher than pumps with cast impellers.

MOTOR

The standard motor is a fully enclosed two-stage air-cooled motor.

2. levels of protection: IP55

3. Insulation grade: F

OPERATING ENVIRONMENT

In order to ensure the proper functioning of the pumps, it is important to consider their operating conditions. The pumps have a maximum operating temperature of +40C. It is crucial not to exceed this temperature, as doing so can result in a drop in the output power of the motors. Similarly, if the pumps are installed at an altitude higher than 1000m, their motors may also experience a decrease in output power. To prevent such issues, it is recommended to use motors with larger output power in situations where the pumps operate at temperatures above +40C or are installed at high altitudes. By doing so, it ensures the efficiency and effectiveness of the pumps even in challenging operating conditions.

According to the given information, installing the pump at an altitude exceeding 3500 meters above sea level results in a decrease in P2 to approximately 88%. Additionally, when the ambient temperature reaches 70C, P2 is expected to drop further to around 78%. It is noteworthy that the alterations in both altitude and temperature have a significant impact on the performance of the pump. Thus, careful consideration should be given to these factors during installation and operation to ensure optimal functioning of the pump.
