There are several components that act as Pump Protectors to help extend the life and durability of the pressure washer pump. Accumulators reduce the pulsations that occur as the incoming water rushes in the pump. Pressure, temperature, and vacuum gauges allow you to monitor the performance of your pressure washer pump to make sure it’s operating at safe levels. Pressure Relief Valves release built up pressure, while a Thermal Relief Valve protects the pump from overheating. Jack’s has accumulators, electric flanges, jetter valves, pressure washer relief valves, gauges, rupture disks, and thermal relief valves. Select the pump protector part you need below or choose from one of our pump protector manufacturers.
