waterelectricstationary

Standardised centrifugal electronic pumps on base with elastic coupling, designed for: circulation of the hot water of the heating system, of the cold water of the air conditioning and refrigeration systems. APPLICATIONS Standardised centrifugal electronic pumps on base with elastic coupling, designed for a wide range of applications, such as: MCE/C: Circulation of the hot water of the heating system, of the cold water of the air conditioning and refrigeration systems. MCE/P: Pressure increase, supply of drinking water and sprinkler and watering systems. CONSTRUCTION FEATURES OF THE PUMP Cast iron single stage spiral body complying with DIN-EN 733 (formerly DIN 24255), seal holder cover and cast iron motor support, flanges complying with DIN 2533 (DIN 2532 for DN 200). Cast iron impeller, closed and dynamically balanced, with compensation of the axial thrust through balancing holes, operation on interchangeable wear rings (on request). Stainless steel pump shaft supported by two permanently lubricated oversized ball bearings, housed inside an appropriate chamber in the support. Standard seal device: standardised mechanical seal according to DIN 24960 in carbon/silicon carbide with EPDM OR rings. Packing with lubricating hydraulic ring and stuffing box in two easily removable parts available on request. CONSTRUCTION FEATURES OF THE MOTOR Closed asynchronous type, external ventilation cooling, 2 or 4 poles. Rotor running on ball bearings, largely oversized to ensure low noise and durability. Controlled by MCE inverter
