J Capacities to 4500 (850 M3/HR) Heads to 370 Feet (78 Meters) Temperatures to 300 F (149 C) 340A/360A SeriesSingle Stage End Suction PumpsModel 362 AModel 344 AModel 341 Apage 2 Setting New Standards of EfficiencyLiquid handling requirements are much more involved than they were five years ago. The variety ofliquids being handled has increased along with temperatures and pressures. Today s installationsdemand quiet, smooth running Pumps with long life. Aurora Pump s 80 years of experience withdesign, sales and manufacturing of centrifugal Pumps has lead to the 340A/360A Series .

2 Thesemodern Pumps with a clean, straightforward design were developed with maximuminterchangeability in mind. Aurora s highly reliable 340A/360A Pumps offer an economical solutionto your liquid handling 340A/360A Pumps Standard 340A and 360 ADischarge position No. 1 Regreaseable bearings (Model 344A, 364A)Standard JM motor (Model 341A, 342A)Standard JP motor (Model 361A, 362A)Coupling guard (Model 344A, 364A)Standard 360a OnlyInterchangeable stuffing boxGraphite impregnated acrylic packingOptional 340A and 360 AStandard 340A and 360a Series Pumps are designedto meet the requirements of most , to meet special services, a number ofoptional features have been made available.
