Bareshaft end -suction Centrifugal Pump IR Single Stage Close Coupled End-Suction Pump at 2900 l/min.

APPLICATIONS

Recircling plants, heating, air conditioning, heat recovery, plants of water supply procurement, pressurising units and fire-fighting systems.

CHARACTERISTICS

Hydraulics: pump body with dimension and performances according to EN 733 rules, closed impeller dynamically balanced and with balance holes for the for the balancing of the axial thrust. Shaft completely in stainless steel, greased ball bearings, flanges (UNI EN 1092-2): up to DN 150: PN16, from DN 200:PN10. Motor: asynchronous with 2 or 4 poles and with external ventilation. The electric pumps can be positioned with horizontal,sloping or vertical axis always with the motor upwards. The operating characteristics of the catalogue and label are to be understood for continuous service and with clear water (specific weight = 1000 kg/m3) with a max manometric suction height of approximately 1,5 m. For higher manometric heights and up to a max of approximately 6-7 m., the characteristics decrease in the various delivery data. The suction piping must be absolutely hermetic and for the catalogue data it must have the following minimum diameters (pipes of smaller diameters reduce the delivery values):

• DN (pump suction) - mm 50 65 80 100 125 150
• DN (suction pipe) - mm 80 100 150 200 250 300
• Protection: IP55
• Insulation: class F
• Standard tensions: 220-240V up to 4 kW, 380-415V / 660- 720V starting from 5,5 kW.
• Frequency: 50 Hz
