Product picture may differ from actual product Product No.: On request Non-self-priming, single-stage centrifugal pump with radial suction and radial discharge port. Pump for the pumping of thin, clean or slightly contaminated, non-aggressive liquids without abrasive or long-fibred solids. The pump has horizontal pump shaft and the housing can be dismantled in the horizontal plane along the drive shaft. Pump and motor are mounted as separate units on a common baseframe and connected via a flexible coupling. The impeller is hydraulically as well as dynamically balanced. Complete unit consists of pump, baseframe, coupling guard and electric motor.
