This arrangement is specifically designed for the pump industry and is available in a variety of industry standard shaft separations. The shaft center spacer drops out to facilitate easier maintenance of pump parts without disturbing the alignment of pump and motor. Spacer type couplings utilize either standard delta hubs or optional round hubs. The center member of the Deltaflex is captured by the construction of the spacer flanges for greater safety. Standard spacer drop out lengths aremore

Coupling Design

Coupling Design

    The Deltaflex coupling is the real solution to installation, misalignment, and performance problems. Conventional couplings – even when carefully aligned to the manufacturer’s specifications – cannot match the low level of vibration, moment of inertia, and additional cushion for future misalignment of a visually aligned Deltaflex coupling.
    In addition, the Deltaflex coupling gives longer life to equipment shaft bearings. That means longer operating time and reduced maintenance cost. The Deltaflex can handle greater shaft misalignment without generating heavy reaction loads on the equipment shaft bearings.
    A properly applied and installed Deltaflex coupling offers more equipment protection compared to conventional couplings.

Features

Features 

  • Maximum misalignment capabilities, with negligible reactionary load, for longer equipment bearing life
  • Operates as smoothly when misaligned as when perfectly aligned
  • No lubrication and no maintenance required
  • Equipment can be visually aligned. No special tools are required, which saves on installation time and cost
  • Eliminates premature equipment bearing and seal failure resulting from misalignment forces. This means greater equipment productivity
  • Torsionally stiff coupling with no backlash means it is capable of high speed applications, within catalog ratings
  • Provides long-term performance and economy
  • Available in 5 basic sizes, from 10HP to 900HP
  • Standard all-metal and stainless steel versions are both available from stock
  • Many configurations are available, including shaft-to-shaft, spacer, floating shaft, and special assemblies

Notes

Notes 

  • Size 50: In some bore sizes the tap is 5/8-18.
  • Maximum bores are provided with standard keyway.
  • RSB hubs do not have a keyway.
  • Both Delta hubs and Round hubs are provided with two set screws at 120°.
  • Minimum bore hubs are furnished with 2 set screws at 120°, No Keyway.
  • S is the Spacer drop out or floating shaft length, S = BE-2(R).
  • LTB is the length through the hub bore. OAL is the overall length, OAL = BE + 2(LTB).
  • BE is the distance between the ends of equipment shafts—please supply this dimension when placing orders, BE = OAL-2 (LTB), BE = S + 2 (R), BE < 18 inch = Spacer coupling (Type 3); BE > 18 inch = Floating Shaft coupling (Type 4). ED
