Drive couplings provide the means by which power is transmitted from the electric motor to the hydraulic pump.

By virtue of their flexible structure, they are able to compensate angular and radial misalignments between motor and pump, and appreciably attenuate the noise generated through the drive line.

The couplings illustrated are available in aluminium and cast iron versions, with a variety of spider options, and will cover a range of applications using electric motors from size 63, rated 0.15 kW, up to size 400 rated 400 kW.

Grub screw on all half-couplings.
Cast iron half-coupling SGEG available with screw mounted.
Steel half-couplings SGES and SGDR available with screw.

Standard ATEX 2014/34/EU
Half-couplings are available to use in hazardous area.
The couplings are certified according to Standard ATEX 2014/34/EU - Category certified 2G - Area 1 and 2.
Other information available on our web site “”.

The half-couplings SGE*** series are in conformity to normative DIN 740/2.
The max torque to transmit is always less than the max torque that the coupling can transmit.
