Design Envelope 4280 End Suction Pumps
Brand: Armstrong Fluid Technology
Base mounted end-suction horizontal pumping unit with integrated intelligent controls for easier installation and superior energy performance. Saves up to 75% in energy over comparable traditional constant speed or variable frequency operated pump installations. Units up to 10hp (7.5kW) include integral vibration isolators.
Features- Integral vibration isolation eliminates the need for inertia bases or baseplates for base-mounted installations
- Split-coupling design enables easy seal service without removal of pump or motor
- Active Performance Management through internet connectivity provides lowest lifecycle operating cost
- No inertia base required for lower installed cost (for 1-10hp only)
- Integrated intelligent controls provide fast and easy commissioning as well as reduced radio frequency interference/ improved electromagnetic compatibility
- Balance rotor design, soft start controls, direct coupling to motor, and reduced overall weight minimize transmission of vibration
- 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)
- Design meets ASHRAE 90.1 noise and vibration control recommendations – isolating transmission of vibration between the piping, pump and floor of the building
- Energy savings through new hydraulics and intelligent motor (for 1-10hp only)
- New hydraulics included in Armstrong intelligent motors (PM Motors) in the 1-10hp range provides up to 30% in energy savings.
- Choose 50:50 of design flow with embedded parallel sensorless control for additional energy savings through best efficiency staging
- 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
- Active Performance Management through internet connectivity on all Design Envelope pumps for lowest Lifecyle operating cost.
