CDLF Multistage High Pressure Pumps

CDLF Multistage High Pressure Pumps

Application FormsealBuy


CDLF multistage high pressure pumps are designed for pressure boosting in the existing water supply system. They feature high head, high efficiency, and little energy consumption.

The impeller and all its parts contacting with liquid are made of stainless steel by pressing and casting. Thus, the flow is smooth, and contamination is prevented. The shaft and the coupling are made of extra strong alloy materials and have mechanical seal that features long service life and prevents leakages.  

The above mentioned features of the pump ensure its quiet regular work. The pump have compact design, is easy to be transported and installed; it is safe for environment. CDLF pumps can be widely used for water supply both in household and industry.

Multistage pumps are made of stainless steel. They are reliable, quiet, easy to be operated, used for municipal, industrial and agricultural facilities, namely, in fire-extinguisher systems, booster systems, water treatment systems, irrigation, hot and cold water supply in heating, cooling and air conditioning systems, and particularly for boiler feed  due to pump robust design.
