The advantages of elastic plate couplings include a high resource, no need for maintenance, a radical reduction in the loads on the supports of the connected machines in comparison with gear tooth-type and pin flexible couplings.
The use of couplings of this type helps to increase the operating time of bearing assemblies, mechanical face seals, reliability and service life of the entire pumping unit as a whole.
An example of elastic plate couplings (EPC) symbol with an intermediate device, a nominal torque of 650 N⋅m, a distance between the half-couplings of 200 mm, a pump shaft diameter of 48 mm, a motor shaft diameter of 75 mm:
