CAT PUMPS is a major supplier of corrosion resistant,
stainless steel pumps for high pressure, seawater desalination, reverse osmosis systems. Our complete
line of 316L and Duplex Stainless Steel desalination
pumps offer corrosion resistance, strength and long life
when pumping sea water under high pressure. We have
many desalination pumps operating in systems on
large ships, offshore platforms, island support and remote locations. All NATO countries have a compulsory reverse osmosis pump use requirement for specific CAT PUMPS models on specific vessels including:
- Submarines = Model 317 or 311
- Corvettes = Model 1057 or 1051
- Destroyers = Model 3537 or 3531
- Air Carriers = Model 6767 or 6761
CAT PUMPS desalination pumps cover flows from .5 to 320 GPM. To meet limited space requirements of some small reverse osmosis desalination systems, we offer compact, direct-drive motor-pump units that are lightweight and have a small footprint. For larger systems we offer our 150 Frame triplex positive displacement pumps with a Duplex Stainless Steel liquid-end. Our desalination pumps offer high energy efficiency, a smooth low pulsation flow and exceptionally long service intervals, plus they are very easy to service on-site. Each pump has custom seal and valve kits for easy periodic maintenance, typically twice per year. Every sea water pump is matched with safety valves for pressure setting and overpressure protection.
