Bypass Operation: Bypass pumps continue to run regardless of pressure in the system by internally bypassing flow if the discharge outlet is closed, staying ready to deliver full power as soon as system outlets are re-opened. The Viton valves and diaphragms provide resistance to corrosion from many types of chemicals, making this pump suitable for agricultural spraying, lawn care, and fluid transfer applications.
