Flow Center is designed for indoor
installaon only.
Flow Center must be installed with
the pump’s motor sha horizontal.
Do not install ow center with the
pump’s motor sha vercal.
The terminal box should be located in
one of the following orientaons:
Grundfos UPS26-99 & Magna GEO variable spd. (requires controller)
High Impact Polystyrene plasc
CFC-free, polyurethane foam
1” Full-port, 3-Way, 4-Posion ushing and isolaon/service valve,
Brass body and spool, NBR seals, stainless steel retaining ring.

Grundfos Magna GEO 32-140 and UPS26-99 (pumps in series)
Pumps operate in series
between these curves*
to maintain flow rate
or temperature diff.
Magna GEO + UPS26-99 (high speed)
Magna GEO (lowest duty cycle -- highest ow/head)
Magna GEO (highest duty cycle -- lowest ow/head)
*UPS26-99 is a constant speed pump; Magna GEO is a variable
speed pump. When both pumps are running, the Magna GEO
operates between duty cycles shown below to maintain
set ow rate or temperature difference.
