9.10 V-belt Transmission
The pump can be controlled by a v-belt system. For these pumps we recommend use of 3 XPB belts (16.5x13
serrated). Use an XPC profile only for long durations. Both the characteristics and transmissible power of each belt can
be verified in the diagram in fig. 7, in relation to the number of RM normally declared by the manufacturer.
Minimum duct pulley diameter (on pump shaft): ≥ 6.3” (160 mm).
The radial load on the shaft must not exceed 4500 N (value necessary for Layout definition). The transmission is
considered adequate if the load is applied to a maximum distance a=50 mm from the shaft shoulder (PTO) as shown in
fig. 10.

9.11 Transmission Definition
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
