Product data Endsuction centrifugal monoblock pumps Introduction The Lubi series are nonself priming, horizontal, singlestage, centrifugal, endsuction pumps. Pumps are available from to 5 HP in singlephase and from 2 to 15 HP in threephase power supply. Motor and pump are close coupled in a convenient and compact design for quick installation in limited space. The pump is fitted with a maintenancefree, mechanical shaft seal and single piece pumpmotor shaft. The pumps have axial suction port and radial discharge port. Applications For suitable liquids which are thin, clean, nonexplosive, nonaggressive, not containing solid particles or fibers. For water supply systems and irrigation. For heating, cooling, airconditioning and circulation plants. For civil, industrial and fire fighting applications. As pressure boosting pump for central water systems with low pressure (follow local specifications if increasing network pressure). Features and benefits Following are the main features and benefits offered by the pumps. Compact design Easy and simple installation Userfriendly operation Low noise level Reliable and robust construction Back pullout design which simplifies inspection and maintenance Operating conditions Flow range Head range Ambient temperature Liquid temperature range Total suction lift : Up to 7 USgpm : Up to 18 feet : Max. +122 F : 2 F to +194 F : Up to 26 feet Pumped liquids These pumps are designed for liquids like potable water, rain water or other than thin, clean, nonaggressive, nonexplosive, not containing solid particles or fibres. Sand content Maximum sand content: 5 g/m³ A higher sand content will reduce the pump life considerably due to wear Pump location The pumps have been designed to operate in a nonaggressive and nonexplosive atmosphere. The relative humidity should not exceed 95%. Curve conditions The conditions below apply to the curves shown the following pages. Tolerances in accordance with ISO 996, Annex A. The motors used for the measurement are standard motors. Test results with clean cold water, without gas content. Measurements have been made with airless water at a temperature of 68 F. Head and power values valid for liquids with density = 1. kg/dm³ & kinematic viscosity = max 1 mm²/s (1 cst). The QH curves apply to a rated motor speed of 45 min ¹. A safety margin of + 2 feet is recommended for the NPSH value. Motor The pump is fitted with a Totally Enclosed Fan Cooled, Cast iron 2pole induction motor. Ratings Rated speed Enclosure class Insulation class Standard voltages : 1 phase, 2 V (Tolerance +5% / 15%) phase, 22/8 V, 2/46 V Supply frequency Duty / Rating Direction of rotation : 1 phase to 5 HP phase 2 to 15 HP : 45 rpm : IP 55 : F : 6 Hz : S1 / Continuous : Clockwise as seen from the motor rear end. Threephase motors must be connected to a motor starter according to local regulations.
