Specification

APPLICATIONS
Standardised centrifugal monobloc electric pumps with coupling, designed for a wide range of applications, such as:
• Central heating
• Water supply
• Air conditioning
• Refrigeration
• Industry
• Fire fighting
• Environmental engineering
CONSTRUCTION FEATURES OF THE PUMP
Non self-priming single stage spiral body centrifugal pump with axial suction port, radial delivery port and horizontal axis components, in compliance with ISO 2858/DIN 24256. KDN pumps have PN 16 nominal sizes and performances.
The suction and delivery flanges are in compliance with EN 7005 PN 10 or 16. All the pumps are dynamically balanced according to ISO 1940 class 6.3; the impellers are hydraulically balanced.
Pump and motor are installed on a single base according to EN 23 661, made of fully welded steel.
Oversize pumps have a base with welded steel profiles.
Thanks to the particular pump design, the bearings, the impeller, and the seal can be removed without detaching the pump body from the piping (backpull-out design).
