Double Suction Horizontal Split Case Centrifugal Water Pump COS200-670 (396-864m3/h @ 80-163m)
COS 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.
The split case pump is the right choice for a wide range of applications with medium to high flow rates. The optimized design of the split case pump ensures high efficiency and durability.
The environmental-friendly split case pump has low maintenance requirements and can be produced in a number of materials according to the specific application requirements. Split case pumps are vailable for a wide range of flow rates and pressure heads. Available in horizontal and vertical execution and one or two-stage.
Features
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.
Easy maintenance
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.
Split-case pumps are the workhorses of industrial and municipal applications. They are more expensive than end-suction or vertical inline pumps, and not as flexible or adaptable as vertical turbines. However, what they lack in low-cost flexibility they make up for in durability, efficiency, and dependability.
A split-case pump, properly installed, designed, and operated, can provide decades of service.Most split-case pumps are axially-split – meaning that the flange at which the pump casing separates is in the same plane as the pump axis. Radially-split pumps are also available, and are commonly used in very high-pressure and high-temperature industrial applications (boiler-feed pumps are one common application for radially-split pumps).
