INTRODUCTION

Today's problem of liquid handling is much more involved than it was five years ago. The variety of liquids being handled has increased along with temperatures and pressures. The costs of engineering and construction have risen considerably. The need for economy and interchangeability in design has become more important. The variety of today's installations demands quiet, smooth-running, long life pumps. The reliability of pump performance has become an essential. The 340/360 series is a modern design based on Aurora Pump's 70+ years experience with the design, sales and manufacture of centrifugal pumps. Significantly, pump Models 341A and 342A offer as standard HI-NEMA Type JM stock motors and Models 361A and 362A offer HI-NEMA Type JP stock motors. Aurora Pump also offers the powerframe mounted Model 344A and 364A.
