Reverse Osmosis Desalination Pumps
There are thousands of CAT Reverse Osmosis Saltwater Desalination systems in use today. There is a ever growing world wide demand for fresh water. Remote areas, islands, offshore platforms, ships and pleasure crafts all use reverse osmosis desalination systems. Reverse osmosis desalination is a very economical means of converting dirty, brackish or seawater to fresh water. CAT PUMPS has developed an extensive line of 316SS and Duplex SS pumps exclusively for the seawater reverse osmosis desalination market. CAT PUMPS unique design and high quality materials offer compatibility, dependability and energy efficiency. Our stainless steel reciprocating pumps offer high efficiency without an energy recovery system. Our compact, lightweight 2SF, 3CP and 5CP Stainless Steel direct-drive models are suited to reverse osmosis units for pleasure craft, while the larger 25 FR, 35 FR, 60 and 150 FR pumps are used in community water, offshore platforms and island support desalination systems. Many of our pumps operate for 7,000-10,000 hours or more before seal replacement is required which means that our pumps are running continuously for long periods of time and meeting your fresh water demands.
