Design Envelope 4380

  • Summary
  • Applications

    HVAC-system pumping and control; general purpose pumping; industrial/process pumping and control (water or glycol based)

  • Description

    Pipe-mounted UL 778 pumping unit with integrated intelligent controls for space-saving installation and superior energy performance. Saves up to 75% in energy over comparable traditional constant speed or variable frequency operated pump installations. Remote services through internet to enhance reliability and sustain optimal performance over life of pumps.

  • Materials
    • Ductile iron e-coated casing
    • Stainless steel impeller
    • Sintered silicon carbide mechanical seal
  • Configuration

    On-board Intelligent Variable Speed controls with Sensorless control. Controls enclosure IP55 or IP66 for outdoor applications. 0.75-7.5 kW range standard with DEPM motors that reduce losses by more than 20% over NEMA Premium efficiency. Network capable for remote performance management services.

  • Performance Range

    1.5 to 28 L/s (25 to 450 USgpm) flow; 3 to 48 m (10 to 160 ft) head (composite curves available)

  • Temperature

    121oC (250oF)

  • Power

    0.19 kW to 7.5 kW (0.25 hp to 10 hp)

  • Size

    25 mm to 150 mm (1" to 6")

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.
  • 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.

Pump Models Designed and Engineered for Outdoor Operation

Controls enclosure rated for UL type 4x. Equipped with overhead weather shield to prevent icing in cold weather or overheating in direct sunlight.

Lowest operating 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
  • Shorter pipe runs for reduced system friction
  • Vertical In-Line configuration allows less disruptive pump service (casing stays in place)

Lowest environmental cost

  • 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

Lowest project and operating risk

  • 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)
