New X-Series Plunger Pumps

Cat Pumps X-Series plunger pumps

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).
