PUMPS
The system has three pumps with the Internal Circulating Loop and a Process Loop each having their
own pump mounted on the main base. A third pump is built into the remote lift station. The system
is designed to provide a nominal 15 GPM (57 LPM) at 45 PSI (0.31 MPa)
The Internal Circulating pump pulls water from the Dirty Side of the reservoir and pumps it through a
cascade of three (3) filters, a chiller and returns the water back to the clean side of the reservoir.
The Process Loop pump pulls clean, refrigerated water from the Clean Side of the reservoir. Pumps it
through a final cascade of two filters (3 filters for the F6 variant) and then out to the process.
The Lift Station pump returns used water back to the Dirty Side of the reservoir.
