Split Case HS Grundfos

Split Case HS Grundfos is a single-stage, non self-priming, between bearing, centrifugal volute pump. The axially split design allows easy removal of the top casing and access to the pump components ( bearing, wear rings, impeller, and shaft seal ) without disturbing the motor pipework.

The Grundfos HS Horizontal pump split case are used for liquid transfer and pressure boosting in these main fields of applications commercial system, industrial systems, water distribution, and irrigation.
