Interpump 71 Series - V-Belt Transmission; Transmission de Nition

ENGLISH
30
9.10 V-belt transmission
The pump can be controlled by a V-belt system.
For this pump model, we recommend use of 4 XPB belts
(16.5x13 serrated). Use an XPC prole only for long durations.
Both the characteristics and transmissible power of each
belt can be veried in the diagram in Fig.7, in relation to the
number of rpm normally declared by the manufacturer.
Minimum duct pulley diameter (on pump shaft): ≥250mm.
The radial load on the shaft must not exceed 7500N
(value necessary for Layout denition). The transmission is
considered adequate if the load is applied to a maximum
distance a=40mm from the shaft shoulder (P.T.O) as shown in
Fig.10.
For dimensions diering from those specied
above, contact our Technical or Customer Service
Departments.

9.11 Transmission denition
To prevent irregular radial loads on the shaft and the relative
bearing, follow these directions:
a) Use pulleys with V-belts with the size of the groove
required/recommended by the manufacturer of belt used.
In the absence of directions, follow Fig.8 and the table in
Fig.9.
