delivery base and the electric motor and allows coupling. (Fig.13)
Two half-couplings allow the transmission of motion from the motor to the pump.
The vertical shaft is in carbon steel or, on request, in stainless steel.
It is fitted with a device against the reversal of rotation.
1.4.3 with pulley (5.1/ 5.2 - Fig.11)
All commands can be supplied in two versions, with groove pulley for traditional belts
or with flat pulley for flat belts.
Allowing an easy coupling to endothermic engines with great elasticity of adaptation

lubricated type, made up of 2 bearings that hold both the axial thrust of the pump
and the radial load generated by the belts. The vertical shaft is in carbon steel or, on
request, in stainless steel. They are fitted with a device against the reversal of rota-
tion. Fig. 14a summarises the couplings to thermal engine by V-belts while Fig.14b
summarises the couplings with flat belts.
