Pump Power Curves
Fluid connections are Flo-Link™ double O-ring
style. Transition ttings are not included with
the ow center packaging. Typically, PE fusion
x Flo-Link is used on the ground loop connec-
tions. A Geo-Flo hose kit designed for Flo-Link
connections includes transition ttings for heat
pump connections.
Flow center may be eld modied to a one
pump ow center by replacing the constant
speed pump with a blank plate kit.

NOTES: The Magna GEO (variable speed)
pump adjusts speed (when used with con-
troller) to maintain ow rate or tempera-
ture dierence. The controller energizes
the constant speed pump (UPS26-99) when
the Magna GEO cannot meet setpoint, and
adjusts the Magna GEO pump accordingly.
Total ow center Was equals constant
speed pump Was plus Magna GEO Was
at design condions. For Was based upon
a specic ow rate and pressure drop, go to
www.geo-o.com, and use the pump sizing
calculator.
