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.
