pressure washer flow switch for sale, brand-new and used.

The General Pump flow switch is designed to operate in response to a low volume, low pressure flow and still allow for a high pump output flow. The system will provide reliable switching with as little as .75 GPM flow and 18 PSI from the city water supply and will also allow pump output flow up to 18.7 GPM @ 4,000 PSI with negligible pressure drop through the valve. General Pump flow switches provide durable, reliable on/off switching for systems that require start/stop capability.
