KSB pump for seawater desalination

KSB has developed a high-pressure pump type series for seawater desalination applications.

The pump sets are intended primarily for use in small to medium-sized installations of the kind commonly found in hotels and large ships or for transportable installations in containers. These have a desalination capacity of up to 10,000 cubic metres of water a day.

The complete pump sets, offered in horizontal long-coupled design, are special variants of the Multitec range. The fact that they are standard pumps means they have a shorter delivery time and are claimed to be more cost efficient than the customised pumps commonly sold in this market segment.

With a discharge head of up to 800 m and a maximum flow rate of 850 cubic metres per hour, the design of the multistage Multitec-RO pumps is robust. They are made from duplex stainless steel in order to cope with the aggressive salt water they handle.

Featuring a low-maintenance ceramic bearing as well as a hydraulically optimised design and easily replaceable wear parts, Multitec-RO offers good operating reliability and low energy and maintenance costs. Due to the axial inlet, the pump set is compact and requires just a discharge-end mechanical seal, making it suitable for space-saving installation.
