Flow Center is designed for indoor
installation only.
Flow Center must be installed with
the pump’s motor shaft horizontal.
Do not install flow center with the
pump’s motor shaft vertical.
The terminal box should be located in
one of the following orientations:
Grundfos UPS26-99 & Magna GEO variable spd. (requires controller)
High Impact Polystyrene plastic
CFC-free, polyurethane foam
1” Full-port, 3-Way, 4-Position flushing and isolation/service valve,
Brass body and spool, NBR seals, stainless steel retaining ring.
UPS26-99 motor: 208-230V, 60 Hz, single phase, 2-pole UL and CSA approved, internal thermal
overload protection, insulation class F, three speed

Flow (U.S. GPM) [l/s]
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 flow/head)
Magna GEO (highest duty cycle -- lowest flow/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 flow rate or temperature difference.
