Product Description

SAER ELECTRIC CENTRIFUGAL IR impeller A 2900 1 min

FEATURES Pump: pump body with dimensions and performance according to EN 733, closed impeller dynamically balanced with balance holes for balancing the axial thrust.  shaft in stainless steel, ball bearings lubricated with grease, flanges (UNI EN 1092-2): up to DN 150: PN16, DN 200: PN10. Mechanical seal: see p. 152, to request special seals. For the construction materials refer to page. 6. Motor: Asynchronous, 2 or 4 poles with external ventilation. Protection: IP55 Insulation: Class F Standard voltage: 220-240V up to 4 kW, 380-415V / 660 – 720V from 5.5 kW. Frequency: 50 Hz DATA suction DN: 50 to 100 (150 to IR4P) –  DN Delivery: 32 to 80 (125 to IR4P). Qmax: 275 m3 / h @ 2900 1/min • 400 m3 / h @ 1450 1/min Hmax 100 m @ 2900 1/min 43 m @ 1450 1/min • Temperature of pumped liquid: from -15 ° C to +120 ° C Maximum operating pressure (see table on page 4 of the catalog). Maximum ambient temperature : 40 ° C (over inquire). Pumps: UNI EN ISO 9906 Appendix A, at the request level 1. Engine: IEC 60034-1. The pumps can be positioned with the axis horizontal, inclined or vertical always with the motor upwards. The operating characteristics of the catalog and label are for continuous service and clean water (specific gravity = 1000 kg/m3) with max manometric suction of 1,5 m for higher manometric heights and up to a maximum of 6 -7 mca, features decrease in the various flow rates. The suction pipe must be absolutely watertight and catalog data must have the following minimum diameters (smaller diameter pipes can reduce the maximum capacity): DN (suction pump) – mm 50 65 80 100 125 150 DN (suction pipe)-mm 80 100 150 200 250 300  SPECIAL VERSIONS Materials of Construction (p. 6) Different mechanical seals (p. 152) Mechanical seal normalized according to UNI EN 12756 Special voltages Frequency: 60 Hz OPTIONS Kit counter flanges Motor protection with PTC Hydraulic characteristics Dimensions and weights Nomenclature
