Product Description

SAER ELECTRIC CENTRIFUGAL MG1 – MG2 WITH RIGID COUPLING

FEATURES pumps with single impeller centrifugal monoblock in coupling, coupled to an induction motor of standard B3/B5 . MG1: bare shaft pump, MG2: complete electric. The coupling is achieved by a complete support of the ball bearing which is fixed on the pump shaft is integrated with a plug-in coupling. The motor unit and the rotating part of the pump can be removed without having to remove the pump from the piping system. Hydraulic: pump body with dimensions and performance according to EN 733, closed impeller dynamically balanced with balance holes for the balance of 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. 30. Engine: 2-pole asynchronous with external ventilation. Mounting position B3/B5 Protection: IP55 Insulation: Class F Standard voltages: 220-240V up to 4 kW, 380-415V / 660-720V from 5.5 kW. Frequency: 50 Hz DATA suction DN: 50 to 100 – DN Delivery: 32 to 80. Qmax 255 m3 / h @ 2900 1/min Hmax: 100 m @ 2900 1/min Temperature of pumped liquid: -15 ° C to +120 ° C Maximum operating pressure (maximum allowable pressure considering the sum of the maximum pressure in the intake and the prevalence at zero flow): Type Body Temperature PN PN max max pump pumped liquid standard request Pumps: UNI-EN ISO-9906 Appendix A – Level 1 on request Engine: IEC 60034-1. INSTALLATION AND OPERATING CHARACTERISTICS The pumps can be positioned with the axis horizontal, inclined or vertical Always use full throttle up. 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, carattetistiche the 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 DN (suction pipe) – mm 80 – 100 – 150 – 200 SPECIAL VERSIONS Materials of Construction (p. 30) Different mechanical seals (p. 152) Mechanical seal normalized according to UNI EN 12756 Special voltages ACCESSORIES REQUEST A counter flanges Kit Motor with PTC protection Hydraulic characteristics Dimensions and weights Nomenclature
