EcoFlow®

Operation

The EcoFlow® 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.

Typical Applications

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.

Seal Water Savings Example

To illustrate the water savings from the case study below that can be realized with EcoFlow®, we’ve used a typical seal manufacturer’s recommendation of 2.6GPM (Gallons per Minute) to be used to flush the seals versus EcoFlow’s ~3GPH (Gallons Per Hour), operating 8 hours a day, 5 days a week (2080 hours per year).

MFR Recommended flow: 2080 hours x 2.6 gallons per minute = 324,480 gallons of water per year.
EcoFlow: 2080 hours x 3 gallons per hour  = 6,240 gallons of water per year.

In our calculation, EcoFlow® can save ~318,000 gallons of water per year.
