CDM, CDMF SERIES
VERTICAL MULTI-STAGE CENTRIFUGAL PUMP
CDM, CDMF SERIES
-
High-efficient non-self-priming vertical multistage centrifugal pump, independently developed according to European standards.
-
Adopts brand-new industrial design, energy efficiency index reaches MEI ≥ 0.7.
-
The impeller guide vane is made of stainless steel plate stamping welding or stainless steel precision casting.
-
The motor is a fully enclosed, air-cooled two-pole standard motor.
Application
CDM/CDMF pumps are designed for a variety of applications from the pumping of potable water to the pumping of industrial liquids. Applied for liquids of different temperatures, different rated flow, and different pressure ranges. CDM is suitable for non-corrosive liquids, and CDMF is suitable for light corrosive liquids.
-
Boosting: Filtering and transferring water in water factories, delivering water in a different zone, pressurizing major pipelines, and boosting high buildings.
-
Industrial Boosting: Cooling and air-conditioning system, cleaning system, high-pressure washing system, fire fighting system.
-
