Carwash Application Spotlight

Cat Pumps pioneered the vehicle wash industry and has been the leading pump manufacturer for over 50 years. In 1968, our original triplex piston pump dramatically improved service life compared to other carwash pumps available at the time. That improvement made Cat Pumps the industry's most dependable pump, with over 85% of car washes using our pumps. Today, our versatility and field-proven long life make Cat Pumps the pump of choice for any vehicle wash system.

Models 7CP6165CSG1, 7CP6165CSG118, and 7CP6185CS Plunger Pumps

Continued research and pump development have led to the new 7CP Series model, built to meet demanding mobile trailer pressure-washing needs. Meticulously designed internal components like solid ceramic plungers, higher-quality seals, and machined stainless steel valves and seats keep pumps running longer. The drive end uses matched connecting rods and oversized bearings to deliver many hours of trouble-free service.

The belt-drive 7CP6185CS turns at 1320 rpm to produce 8 gpm at up to 3,500 psi—the lower rpm results in longer seal life and reduced pump maintenance. Gearbox models allow the pump to run at about half the engine's speed. This design increases pump longevity in continuous-duty applications, provides an easy-to-assemble compact footprint, and eliminates the need for cumbersome belts and pulleys. The model 7CP6165CSG1 pairs to an engine with a 1" horizontal shaft, and model 7CP6165CSG118 mates with a 1-1/8" shaft.

The new 7CP models are what you expect from Cat Pumps — high-quality, dependable products backed by the industry's best customer service and support.

Typical Applications:
• Mobile Pressure Wash
• Surface Preparation
• Water Jetting
• Hydro Excavation
• Wash Down
