  • 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 10hp (7.5kW) include integral vibration isolators.

  • Materials
    • Cast-iron or ductile iron casing / ductile iron e-coated casing on units 1-10hp
    • Bronze impeller (stainless steel available on units up to 10hp)
    • Sintered silicon carbide mechanical seal
  • Configuration

    On-board Intelligent Variable Speed controls with Sensorless control. Controls enclosure UL Type 12 (IP55) indoor applications. 1-10hp (0.75-7.5 kW) 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

    25 to 4500 USgpm (1.5 to 283 L/s) flow; 10 to 400 ft (3 to 121 m) head (composite curves available)

  • Temperature

    300oF (150oC) 
    250oF (121oC) - for units up to 10hp

  • Power Range

    1 hp to 125 hp (0.75 kW to 90 kW)

  • Size

    1.25" to 8" discharge (32 mm to 200 mm)

lowest first installed and lifecycle operating cost

  • 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)
Design Envelope

Lowest installed cost. Lowest operating cost.

lowest project and operating risk

  • 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)
