Cat Pumps introduces the X-Series, a new line of plunger pumps designed specifically for seawater reverse osmosis (SWRO) and other harsh desalination applications. Built on Cat Pumps' original wet-seal design and enhanced with proprietary packing technology, X-Series pumps deliver up to three times longer seal life than standard designs. The result: more uptime, fewer service calls, and lower total cost of ownership in the world's most demanding applications.
Key Features
- Innovative high-pressure packings extend seal life up to 3x longer.
- Corrosion-resistant 316 or duplex stainless steel wet-ends provide superior durability in saltwater.
- 36-frame valve plate covers eliminate threaded stainless steel valve plugs.
- High-strength connecting rods and plunger rods ensure continuous-duty SWRO performance, even at low RPM.
- Exclusive internal crankcase oil porting delivers critical crosshead lubrication, reducing wear during long runs.
- Precision 316 or duplex stainless steel valve assemblies ensure saltwater resistance and reliable sealing.
- 36-frame plunger sleeves reduce wear and extend seal performance.
- Proven wet-seal design keeps seals internally cooled and lubricated – ideal for scale-prone RO feedwater.
- Flow range: 10–45 GPM (38–170 l/min).
- Pressure range: up to 2,200 PSI (152 bar).
