5CP4100CSS Series Modular Unloaders

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.

Lightweight and compact, these unloader valves are the perfect choice for bolt-on unloader valve installation in the discharge line to relieve excessive pressure. Since these products are from Cat Pumps, you know they are built to last. Keep your equipment safe and running with Cat Pumps.

Features:

  • Provides system pressure regulation and protection for on/off trigger gun applications.
  • A built-in bypass channel eliminates the need for an external bypass hose.
  • Convenient flow-through screws allow easy, compact direct mounting to the pump.
  • The grooved plastic handle permits easy pressure adjustment.
  • A chemical injector allows for downstream chemical injection.

Typical Applications:

  • Mobile Pressure Wash
  • Surface Preparation
  • Water Jetting
  • Hydro Excavation
  • Wash Down
  • Sewer Jetting
