Design Envelope 4300 Pumps

« Back

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. Split-coupling design and outside balanced or inside single spring mechanical seal. Controls enclosure UL type 12 or UL type 4X for outdoor applications. 1-10hp range standard with DEPM motors that exceed IE4 Efficiency IEC 60034-30-1. Network capable for remote performance management services.

ADEPT Select

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.

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

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
