Cat Pumps drive-ends have a reputation for being the longest-lasting, most durable pump drive-ends on the market. After decades of use, or through oil contamination of the drive-end, oil can sometimes leak past the seals. Typically, the proper method of replacing crankcase oil seals is complicated and involves removing the two bearing covers, the crankshaft and bearings, and the plunger rod and connecting rod assemblies before finally removing the oil seals. This method is time-consuming but prevents scoring of the plunger rods when using a sharp pick to remove the oil seals.

High-Quality Primary Pressure Protection

By building on the simplicity and strength of our existing modular unloaders, Cat Pumps engineers have created this design to match our 5CP4100CSS Series Pumps to meet the demands of our customer's high-pressure application needs. Model 7865 features a 2.1 mm orifice chemical injector, and model 7866 has a 1.8 mm orifice. For applications where an injector is not required, model 7867 includes a standard discharge fitting.

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

Continued research and pump development has led to the new 7CP Series model pump being 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 provide many hours of trouble-free service.

The Ultimate Protection for Winter Storage of Pressure Washer Pumps

Pressure washer pumps can be adversely affected during long-term storage, especially in cold temperatures. That's why Cat Pumps developed the best solution: Pump Protector.

Models 7CP6165CSG1 and 7CP6165CSG118 Gearbox-Drive Plunger Pumps

Cat Pumps engineers continue to expand the 7CP Series pumps by adding a gearbox that allows the pump to run at about half the engine’s speed. This design increases the pump’s longevity in continuous-duty applications, allowing for an easy-to-assemble compact footprint and eliminating the need for cumbersome belts and pulleys.
