Double Suction Split Case Sea Water Pump COS200-320

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.

COS series Split case centrifugal pumps feature a single double suction or two single suction impellers supported between bearings. The casing is split axially, with opposing suction and discharge flanges, greatly simplifying maintenance. With balanced bearings and a robust overall design it’s not uncommon to find a horizontal split case pumps still in use after 30 years of service.Suitable for electric or diesel engine, our COS series split case pump duties range from 50m3/h to 20,000m3/h, head range from 15m to 220m.

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 optimized design of the split case pump ensures high efficiency and durability. The split case pump has low maintenance requirements and can be produced in a number of materials according to the specific application requirements. It is available in both horizontal and vertical configurations, which enables a great deal of installation flexibility. Split case pumps are available for a wide range of flow rates and pressure heads.​

Main Benefits:
* Reduced energy consumption
* Less environmental impact
* Low operating costs
* Extended service life and durability
* Low vibration and noise levels
* Upgrading of existing pumps

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.

Ease of 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.
