Setting New Standards of Efficiency
Liquid handling requirements are much more involved than they were five years ago. The variety of liquids being handled has increased
along with temperatures and pressures. Today’s installations demand quiet, smooth-running pumps with long life. Aurora Pump’s 90 years of
experience with design, sales and manufacturing of centrifugal pumps has led to the 340A/360A Series. These modern pumps with a clean,
straightforward design were developed with maximum interchangeability in mind. Aurora’s highly reliable 340A/360A pumps offer an economical
solution to your liquid handling problems.
End suction products such as the flexible coupled horizontal pump seen above are used in offices and high rise buildings for
internal environment control. End suction pumps come in a variety of configurations including close coupled, flexible coupled,
horizontal or vertical mounted units.
