Multistage pumps
CDLF multistage pumps
Multistage pumps of the CDLF seriesdesigned to increase pressure in an existing water supply system. They are high pressure, highly efficient and do not consume much energy.
The impeller guiding the impeller and all parts in contact with the liquid are made of stainless steel by stamping and casting, which means the flow path is smooth and prevents contamination. The shaft and coupling are made of high quality carbide and have a mechanical seal that lasts long and does not leak. All features of the pump ensure quiet, uniform operation. The pump has a compact design, easy to transport and install, and environmentally friendly. CDLF pumps can be widely used for domestic and industrial water supply. Multistage pumps are made of stainless steel. Reliable, quiet and easy to operate pumps are used in municipal, industrial and agricultural facilities. For example, in fire extinguishing systems, booster systems, water treatment, irrigation, hot and cold water supply in heating, cooling and air conditioning systems, especially for feeding boilers due to the reliable design of the pump.
