A careful assessment of historic mechanical problems has led to the design of a low-bulk elastic joint in our motors. We place this in the coupling between the crankshafts and pump and it greatly reduces the inevitable vibrations, eliminates axial thrusts, and absorbs dynamic forces due to misalignment in the shafts. The elastic coupling integrated in the unified flange has allowed the supply of a complete component and eliminated assembly of an external joint or direct couplings between engine and pump. The elastic coupling also fulfills the problem of galvanic currents which naturally are triggered in the humid microcircuits between two coupled shafts.
The sealed bearings are largely sized and lubricated with Lithium-based grease which allows for high performance use from -13 to 302 °F
