Lowest installed cost

Vertical In-line design eliminates the need for inertia bases, housekeeping pads, and flex connectors and reduces piping requirements
Integrated intelligent controls eliminate separate mounting of variable frequency drive (VFD) as well as procurement, installation (incl. wiring), calibration and upkeep of differential pressure sensor
Vertical motor positioning requires up to 60% less floor space compared to other pump configurations.
Expertly staggered product line for perfect pump match-up and selection especially in retrofit situations
Superior energy performance qualifies for significant cost recovery under utility and government rebate programs
Design Envelope selections frequently recommend a smaller motor and/or pump which reduces installed cost.

Integrated intelligent controls – combined with perfect component match-up and tuning – for up to 75% in energy savings over traditional constant speed and variable frequency operated pump installations
Split-coupling design for easy seal service without removal of pump or motor
