Benefits & Features

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.

75% decrease in energy consumption reduces operational greenhouse gas emissions at equal ratio.
Elimination of inertia bases, housekeeping pads, flex connectors and superfluous piping avoids all procurement related environmental impacts. (material, energy, carbon)
Equipment downsizing mitigates environmental impacts associated with procuring unnecessarily large equipment.
Integrated design packs and ships more economically for less packaging waste compared to loose component shipping and assembly.

Integrated intelligent controls for fast and easy commissioning as well as reduced radio frequency interference/ improved electromagnetic compatibility.
Optional performance management for early warnings, online trending and analysis, and reports and summaries.
Optional sediment filters or separators for extended seal life in contaminated systems.
Single-source responsibility for optimum design and field support.
Independent operation through embedded Sensorless control or in conjunction with a building automation system (BAS)
