End Suction HVAC Pumps Design Envelope 4200H

« Back

Summary
Applications
End Suction pumps for HVAC system pumping and control; general purpose pumping; industrial or process pumping and control (water or glycol based)
Description
End Suction, base mounted 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 7.5kW (10hp) include integral vibration isolators.
Materials
- Cast-iron or ductile iron casing / ductile iron e-coated casing on units 0.75-7.5kW
- Bronze or stainless steel impeller on units 0.75-7.5kW
- Sintered silicon carbide mechanical seal
Configuration
On-board Intelligent Variable Speed controls with Sensorless control. Controls enclosure IP55 (UL Type 12) indoor applications. 0.75-7.5 kW (1-10hp) range standard with Design Envelope permanent magnet (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 283 L/s (25 to 4500 USgpm) flow; 3 to 121 m (10 to 400 ft) head (composite curves available)
Temperature
150^oC (300^oF)
121^oC (250^oF) - for units up to 7.5kW
Power
0.75 kW to 90 kW (1 hp to 125 hp)
Size
32 mm to 200 mm discharge (1.25" to 8”)

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)
