Double Suction Horizontal Split Case Water Pump 250S65 (330-620m3/h @ 49-71m)
S Series pumps are double suction horizontal split case centrifugal pump, they are single-stage, double suction, horizontally mounted, applied for general water supply, booster service, municipal waterworks, condenser cooling, water circulation, industrial service, building service, chemical plant, power plants etc.
High efficiency
The shapes of impeller and pump casings are optimized to achieve the highest possible efficiency for the specific design flow rate and pressure head. Off design characteristics are optimized to give each pump a wide operating range, ensuring that cavitation limits are not exceeded.
Easymaintenance
The pumps are easy to maintain as the upper half can be removed without dismantling pipe connections and driver components so that the alignment is not disturbed. In addition, our service department offers financially attractive service and maintenance contracts, which guarantee that downtime in pumping installations is kept to a minimum.
Durability
By using double suction impellers and double volute casings Sanchang supplies pumps with low vibration and noise levels. A double volute reduces radial thrust, resulting in longer service life for bearings and seals.
