Series SD split case water pumps are single stage, double suction with horizontally split casings. They are suitable for pumping unsettled water, clean water, non-drinkable or hydrocarbon at a temperature not exceeded 105C degree.
SD split case pumps are available for capacities of 68-18000m3/hr and head of 7-240m. It has the following advantages compared the common double suction pump:
Innovative Casing:
-- In-line design
--Short distance between bearings and correspondingly short shaft
-- Leak-tight due to compact joint flange with long, prestressed bolts
-- Counter-rotation possible with similar parts
Service-Friendly Shaft:
-- Completely sealed and dry for zero corrosion
-- Short and rigid with negligible vibrations
-- Replaceable shaft protecting sleeves
-- No threads exposed to pumped medium, long operating lift and no corrosion
-- Adjustment-free assembly
High-Performance Impeller:
-- Minimal axial thrust due to double entry impeller
-- Optional impeller wear rings
-- New vane passage with excellent hydraulic characteristics
Excellent efficiencies, Outstanding NPSH:
-- Computer-optimized double entry impellers
-- Smooth surfaces inside the casing and on the impeller
-- Smooth, quiet running also gurantted by a large impeller eye area
-- No drop in efficiency due to cost effective replaceable casing wear rings and impeller wear rings
-- Smooth, low loss running due to a swirl-free inlet
