Cat Pump 7501 Stainless Steel Pressure Sensitive Regulating Unloader
The Cat Pump 7501 SS Pressure Sensitive Regulating Unloader is engineered to deliver precise and reliable pressure control in high-pressure cleaning systems. Built from durable 316 stainless steel, it provides excellent corrosion resistance, making it suitable for demanding industrial and commercial environments. Designed for single pump or single gun operation, this unloader maintains consistent system pressure and automatically diverts flow to bypass when the trigger is released or flow is obstructed.
Its pressure-sensitive design allows for a wide operating flow range while ensuring rapid return to full pressure when the system resumes operation. This results in smoother performance, reduced wear on components, and improved operational efficiency. The adjustable cap allows for easy pressure tuning, making it adaptable across a variety of pressure washing and fluid handling applications.
Compact yet powerful, the 7501 unloader is ideal for intermittent cleaning systems where dependable pressure regulation is critical. Its rugged construction and precision engineering make it a trusted solution for professionals who demand consistent performance and long service life.

FAQ
What makes the Cat Pump 7501 unloader pressure-sensitive?
It reacts to downstream pressure changes, automatically shifting to bypass when flow stops and restoring pressure instantly when flow resumes.
Can this unloader be used in continuous duty systems?
It is best suited for intermittent duty applications rather than continuous weep systems.
Is the pressure adjustable?
Yes, the built-in adjusting cap allows precise tuning of system pressure.
Why is stainless steel construction important?
316 stainless steel provides high resistance to corrosion, making it ideal for harsh or chemical environments.
Does the unloader require a bypass flow?
Yes, a 5–10% bypass flow is recommended for optimal performance and longevity.
