Horizontal, axially split case pumps HI design (BB1 & BB3)

SPLIT CASE PUMPS The outcome of many years of experience in the design and manufacture of centrifugal pumps, the Ruhrpumpen HS / ZW pumps are single- or multi-stage, single or double volute, axially split case centrifugal pumps. The HS range (HSC, HSD, HSL, HSR and HSM models) and the ZW pump are designed and built according to the Hydraulic Institute (HI) standard (BB1 & BB3 types). Depending on mechanical features and material selection, they can pump various fluids providing maximum reliability in general industry applications, power generation plants, municipal water systems, mining...

SPLIT CASE PUMPS WEAR RINGS Casing wear rings are standard and replaceable on all pumps. Impeller wear rings are optional. IMPELLER Double suction, dynamically balanced impellers held in place by separate nuts. SHAFT A rigid shaft combined with doublevolute casing results in low shaft deflection at all operating points. Low deflection reduces packing wear, ring wear and bearing loading, which ultimately results in sustained efficiency and economic operation. SHAFT SLEEVE Separate shaft nuts feature provides the greatest simplification of sleeve replacement. Sleeves are sealed to shaft by an...
