The mechanical seal support system contains a highly reliable and repeatable thermal actuator that continuously senses the seal water temperature. If the seal water should exceed the specified factory set-point the valve will modulate open discharging the hot water, displacing it with cool water. This cooler water will cause the EcoFlow® to modulate closed. This cycle will continue to occur as long as excessive heat is being transferred to the seal water causing the water temperature to exceed the valve’s factory set-point.
The EcoFlow® valve is installed on the seal water outlet of a double mechanical seal to continuously maintain a constant seal water outlet temperature. This increases seal life by ensuring an optimum seal environment while drastically reducing water consumption and significantly increasing cost savings.
