About


Bellhousings are the mechanical elements used to
connect an electric motor equipped with standard
flange to a hydraulic pump, thus forming the
pump/motor unit. The bellhousings of this range allow
to establish a perfect assembly between electrical
motors with standard flange up to 270 kW and the
majority of the hydraulic pumps available on the world
market. They are produced in alluminium alloy and
can be divided into two categories:

SINGLE PIECE BELLHOUSING
made of a single piece

COMPOSITE BELLHOUSING
made of several components
– base bellhousing + flange
– base bellhousing + distance ring + flange
Composite bellhousings are employed under the fol-
lowing conditions:
1. The dimension "H1" of the base bellhousing is infe-
rior to the summed length of motor and pump
shafts plus spider.
2. The fixing points of the pump are not compatible
with the fixing holes of the bellhousing.

Necessary indications
for the choice of the correct bellhousing
1. Power of the motor (tab. motors see pag. 21/29).
2. Dimensional data of the hydraulic pump.
