DESIGN FEATURES
Suction and discharge flanges comply with EN 7005 PN 10 or 16. All pumps are dynamically balanced according to ISO 1940 class 6.3, impellers are dynamically balanced by compensating axial forces using balancing holes. The pump and electric motor are mounted on a common steel support frame in accordance with EN 23 661. Thanks to the design of the hydraulic part, servicing can be carried out without removing the hydraulic housing from the pipeline. The pumps are equipped with a two, four or six-pole air-cooled asynchronous electric motor. Electrical protection: in accordance with ELECTROMAGNETIC COMPATIBILITY DIRECTIVE EEC 89/336 and subsequent amendments, LOW VOLTAGE Directive EEC 73/23 and subsequent amendments, also conforms to CEI 2-3 standards.
