How are the claw couplings joined together?
Claw couplings (with the same claw distance) are connected by pressing two couplings against each other and rotating. The claws engage in the gaps in the claws of the opposite half.
Is the type of material of the claw coupling relevant?
Yes, it is. Before choosing the material, it is necessary to determine what medium these couplings will be used for. Standard coupling materials include zinc-plated cast iron, brass and stainless steel. In addition, the sealing material must be chosen: NBR or Viton.
Is the claw distance important when it comes to claw couplings?
The claw distance does matter, as there are different types of claw couplings. The most popular claw distance is 42mm, 41mm and 40mm (so-called GEKA couplings). Never join couplings with different claw distance.
