36 Frame XD-Series Plunger Pump

Industrial Duty, Long Lasting, Dependable Pumps

Model: 3621XD

This triplex (three plunger rods) positive displacement, reciprocating plunger pump is part of the Cat Pumps XD-Series, engineered specifically for low-lubricity deionized (DI) water applications. The model 3621XD features a 316 stainless steel inlet manifold, duplex stainless steel discharge manifold, 316 stainless steel valve assemblies, solid ceramic plungers, and standard NBR (Buna-N) O-rings.

XD-Series pumps incorporate advanced X-Series high-pressure packing technology along with a proprietary low-pressure seal design that eliminates the need for a freshwater flush. A precision-machined crankcase with upgraded connecting rod and plunger rod materials ensures smooth, continuous-duty performance in ultra-pure DI water applications.
