Grundfos-pumppu CR3-4 a-a-a-e-hqqe

CR 3-4 A-A-A-E-HQQEVertical, multistage centrifugal pump with suction and discharge ports on same the level (in-line) enabling installation in a horizontal one-pipe system. The pump head and base are in cast iron – all other wetted parts are in stainless steel. A cartridge shaft seal ensures high reliability, safe handling and easy service and access. Power transmission is via a split coupling. Pipework connection is via oval flanges with internal Rp threads.The pump is fitted with a 3-phase, fan-cooled asynchronous motor.{br}Liquid:Liquid temperature range:-20 .. 120 °CTechnical:Speed for pump data:2873 rpmRated flow:3 m3/hRated head:19.1 mShaft seal:HQQEApprovals on nameplate:CE,TRCurve tolerance:ISO 9906:1999 Annex AMaterials:Pump housing:Cast ironPump housing:EN-JL1030Pump housing:ASTM A48-30 BImpeller:Stainless steelImpeller:DIN W.-Nr. 1.4301Impeller:AISI 304Installation:Maximum ambient temperature:40 °CMax pressure at stated temp:16 bar / 120 °CMax pressure at stated temp:16 bar / -20 °CFlange standard:OVALPipe connection:Rp 1Flange size for motor:FT85Electrical data:Motor type:71AIE Efficiency class:NANumber of poles:2Rated power - P2:0.37 kWPower (P2) required by pump:0.37 kWPower (P2) required by pump:0.37 kWRated voltage:3 x 220-240 D/380-415 Y VRated current:1,74/1,00 AStarting current:490-530 %Cos phi - power factor:0,80-0,70Rated speed:2850-2880 rpmEfficiency:78,5%Motor efficiency at full load:78,5 %Motor efficiency at 3/4 load:79,0-76,5 %Motor efficiency at 1/2 load:75,5-71,5 %Enclosure class (IEC 34-5):55 (Protect. water jets/dust)Insulation class (IEC 85):FOthers:Minimum efficiency index, MEI =:0.7Net weight:18.7 kgGross weight:21.4 kgShipping volume:0.05 m3
