Couplings for Interpumps

Couplings for Interpumps

  • In the event INTERPUMP flanges and couplings are used (available for a range of models), correct connections is guaranteed by the accuracy in the machining of INTERPUMP components and the same is also true of INTERPUMP gear reducers. With this type of coupling, take care to fix the motor to the base of the unit (using rails or silent blocks if needed), leaving the pump free
  • If the pump is driven with belts and pulleys, pay special attention to pulley alignment and belt tension (to do this, the pump must be assembled on a special belt-tightener slide with adjusting screws). Please note that if the belts are too tight, the oil could overheat and reduce bearing life. For more information on pulley and belt size, please refer to the technical specifications supplied by the manufacturer of the transmission belts
  • Direct coupling using a flexible joint without flange is more difficult. In this case, both the pump and motor are attached to the unit base and, before connecting pump to motor, the two shafts must be perfectly aligned, if necessary using spacers under the feet of the pump or motor. The purpose of this is to avoid pressure on the pump and motor bearings. If the pump has been coupled using the joint or belts and pulleys, all exposed moving parts must be protected with joint- or belt-guards
