Grundfos LS is a horizontal, single-stage or double-stages, between bearings, split case pump. 

The axially split design allows easy removal of the top casing and access to the pump components 

without disturbing the motor or pipe work.Â

LS 500-400-423A ,1F1DBBBQE1 220/4

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.
