PUMP The GRUNDFOS CR 3 Pumps are vertical, multistage centrifugal pumps with suction and discharge ports on same the level (in-line) enabling installation in a horizontal one-pipe system. They are suitable for water supply, irrigation, liquid transfer and boosting applications. The heavy duty pumps are designed for continuous duty in commercial & industrial installations. The pump head and base are in cast iron – all other wetted parts are in stainless steel. A cartridge shaft seal ensures high reliabil-ity, safe handling and easy service and access. For aggressive liquids the 'N' version is available which features stainless steel AISI 316 top and bottom pump housings. Power transmission is via a split coupling. MOTOR The pumps are coupled to totally enclosed fan cooled 2-pole GRUNDFOS motors complying with IEC and DIN standards. The high efficiency class IE3 motors have ‘blueflux” logo. Single phase motors have a built-in thermal overload switch, though a standard remote starter is recommended. Three phase motors are connected to an effective motor starter in accordance with local regulations or to a Grundfos CUE controller for optimal performance. Enclosure Class: IP55 Insulation Class: F Speed: 2900rpm Voltage: 3 x 380/415V OPERATING CONDITIONS Pumped liquids: Thin, clean, non-aggressive and non-explosive liquids without solid particles or fibres.
