Description
Benefits & Features
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 VFD and the associated procurement, installation, calibration, and maintenance of differential pressure sensors.
- 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 utility and government rebate programs.
- Design Envelope selections frequently recommend a smaller motor and/or pump which reduces installed cost.
Lowest operating cost
- Integrated intelligent controls with matched components allow up to 75% energy savings over traditional constant speed or VFD-operated systems.
- Split-coupling design allows for easy seal service without removing the pump or motor.
Lowest environmental cost
- 75% decrease in energy consumption significantly reduces operational greenhouse gas emissions.
- Eliminates need for excess installation components, reducing material, energy, and carbon footprint.
- Equipment downsizing lowers environmental impact associated with oversized equipment procurement.
- Integrated design enables efficient packing and shipping, resulting in less packaging waste.
Lowest project and operating risk
- Integrated intelligent controls enable faster commissioning and improved electromagnetic compatibility.
- Optional performance management provides early warnings, analytics, and reports.
- Optional sediment filters or separators extend seal life in contaminated systems.
- Single-source responsibility ensures optimal design and support.
- Sensorless control enables independent operation or integration with BAS.
- ETL Listed – conforms to UL STD 778; Certified to CSA STD C22.2 NO.108.
