centrifugal pump dab KDNE MCE-C
centrifugal pump dab KDNE MCE-CStandardized centrifugal pumps complete with flexible coupling and MCE/C drive on a common frame are designed for a wide range of applications, such as:
- Circulation of hot water in systems heating.
- Circulation of cold water in air conditioning systems.
- Circulation of cold water in cooling circuits.
DAB's MCE/C inverter provides the ultimate in flexibility and performance, allowing the pump to automatically adapt to varying system requirements and maintain a constant differential pressure.

DESIGN FEATURES
The hydraulic housing is made of cast iron and meets the requirements of the DIN-EN 733 standard (installation . DIN 24255). The mechanical seal flange and motor support are made of cast iron. The flanges meet the requirements of DIN 2533 (DIN 2532 for DN 200).
Closed cast iron impeller dynamically balanced by axial force compensation via balancing holes, impeller neck wear ring to reduce hydraulic losses (available on request). The pump shaft is made of stainless steel and rotates on oversized bearings located in the intermediate support of the hydraulic part of the pump, filled with liquid lubricant.
DIN 24960 standard mechanical seal graphite/silicon carbide with EPDM sealing rings. Pumps with gland seals are available on request. The pumps are equipped with a two-or four-pole air-cooled asynchronous electric motor. To ensure low noise levels and increase engine life, the rotor rotates on oversized bearings. Electrical protection: The motor design complies with the requirements of the EMC Directive EEC 89/336 and subsequent amendments, the Low Voltage Directive EEC 73/23 and subsequent amendments, as well as the requirements of CEI 2-3 standards.
