DB 2



Application

The DAYLIFF DB range of horizontal multistage centrifugal pumps is designed for continuous duty in various water transfer applications. These pumps have compact dimensions, an axial suction port, radial discharge port, and are base plate mounted. The suction chamber and pump head are made of grey cast iron, while the impeller and impeller housing are made of stainless steel. The pump and motor unit are of a monoblock design, with special attention given to quietness and smooth operation. Here are some applications where the DB pump range can be used:

1. Water Transfer Systems: The DB pumps are suitable for water transfer applications in commercial, residential, and industrial settings. They can efficiently transfer water from one location to another, whether it's for filling tanks, supplying water to different parts of a building, or distributing water in a water distribution network.

2. Building Water Supply: These pumps can be used to supply water to buildings, including high-rise structures, hotels, apartments, and offices. They ensure a reliable and consistent water supply for various purposes, such as drinking water, sanitation, firefighting systems, and general water usage.

3. Pressure Boosting: The DB pumps can be employed in pressure boosting systems to increase water pressure in buildings or systems where higher pressure is required. They can enhance the water flow and pressure to meet the specific needs of equipment, machinery, or processes that require adequate water pressure.

4. Industrial Water Transfer: These pumps are suitable for transferring water in industrial applications. They can be used in manufacturing plants, factories, and industrial processes where the efficient movement of water is necessary for cooling, equipment operation, or other industrial applications.

5. Irrigation Systems: The DB pumps can be utilized in small to medium-scale irrigation systems. They can provide the necessary water pressure and flow for watering gardens, lawns, agricultural fields, and landscaping projects, ensuring optimal hydration for plants and vegetation.

Proper installation, regular maintenance, and monitoring are essential to ensure optimal performance and longevity of the DB pumps in each application.
