Original Press Release:

66DX Plunger Pump - New Frame, Same Greater Performance

CAT PUMPS announces the renaming of its popular direct-drive Plunger Pump used by many in portable pressure washers. After thousands of pumps, the mold needed to be replaced. The crankcase was designed with a great new look, yet the same reliable internal components are used on the new 66DX models. The high quality materials and unique design of the 66DX Series Pumps offer superior reliability and long life at a very affordable price.

The rugged eight-bolt forged brass manifold head, oversized high-strength connecting rods, concentric, solid ceramic plungers and forged, hardened crankshaft provide considerably longer life and better overall performance than the competition. This compact direct-drive pump delivers an impressive 4000 PSI. Other features of the 66DX pump that assure a high return-on-investment include:

o CAT PUMPS specially formulated Hi-Pressure Seals are field proven to last long under high pressure and yield the greatest number of operating hours.

o CAT PUMPS field-proven, concentric, high-density, solid ceramic plungers provide extended seal life and better overall pump performance.

o V-Packings are reinforced with Male Adapters offering greater endurance under high pressure.

o Flange-design permits easy, quick direct-mounting to most gas engines increasing flexibility and compactness.

o Compact, modular Pressure Regulating Unloader with built-in bypass and fixed chemical injector is available on each pump for insured reliability. Handle permits precise system pressure setting.

o Snap together, interchangeable 304SS inlet and discharge Valve Assemblies offer easy pump servicing and minimum parts inventory.

o Heavy-duty eight-bolt, reinforced Forged Brass Manifold Head offers exceptional strength and durability. So strong it can be frozen without being damaged.

o Crankshaft supported by dual, heavy-duty ball bearings to assure greater bearing load and longer life.
