Product Description
GP 100557- 3/8″ Pump Thermal Protector
Protects the pump from damaging heat build-up while it is in bypass mode.
The thermal relief valve, sensing a rise in temperature, opens and discharges a small amount of heated fluid.
This allows cooler water to enter the system and cool the pump. When the gun is discharged the cooler water will cause the valve to close immediately.
