CDLF Series Multistage Pumps
CDLF series multistage pumps are designed to pressurize an existing system water supply. They are high pressure, highly efficient and do not consume much energy.
The impeller, the impeller guide 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 pollution. The shaft and coupling are made of high quality carbide and have a mechanical seal, which serves for a long time and does not leak.
All pump features ensure quiet, uniform operation. The pump has a compact design and is easy to transport and install, safe for the environment. CDLF pumps can be widely used for water supply in everyday life and industry.
The 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 systems fire extinguishing, booster systems, systems for water treatment, irrigation, hot and cold water supply in heating, cooling and air conditioning systems, especially for supplying boilers thanks to reliable pump design.
Multistage pumps
Applications
- Water supply: water filtration and its supply through water supply networks, pressure increase in plumbing and in multi-storey buildings.
- In industry: process water, flushing system, flushing system under pressure, fire extinguishing system.
- Industrial water supply: cooling and air conditioning system, water supply to boiler, condensation system, production plants, work with acids and alkalis.
- Water treatment: ultrafiltration system, reverse osmosis system, distillation system, separation, use in pools.
- Irrigation: agricultural land irrigation, spray irrigation, drip irrigation irrigation, etc.
