The couplings are used to establish a connection
between an electrical motor with standard flange and
a pump. The couplings of this range allow to establish a
perfect assembly between electrical motors with
standard flange up to 315 kW and the majority of the
hydraulic pumps available on the world market.
HALF COUPLINGS ND series
Made in alluminium, with precast minimal boring (elastic type)
Motor Power: 0,12÷90 kW. HALF COUPLINGS NS series
Made in alluminium, blank (elastic type)
Motor Power: 0,12÷90 kW. HALF COUPLINGS NDG series
Made in spheroid iron, blank (elastic type)
Motor Power: 2,2÷200 kW. HALF COUPLINGS OMT series
Made in steel, available blank or with machined front
In the following cases the halfcouplings are machined
from blank raw parts:
1. The length of the ND type halfcoupling is not sufficient
to realize the required complete coupling.
2. The diameter of the precast minimal boring is too
big to allow correct fixation on the pump shaft.
3. The diameter of the head is too small to allow the
realization of the required pump side boring.
Motor Power: 0,12÷100 kW. |
Necessary indications
for the correct choice of a halfcoupling
1. Power of the motor (tab. motors see pag. 17 in the
catalogue).
2. Dimensional data of the hydraulic pump.
