VK SERIES
9.10 V-belt Transmissions
V-belt transmission is only allowed on versions without a reduction gear.
For this pump model, we recommend use of 4 XPB belts (16.5 x 13 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. 9, in rela-
tion 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 7,500 N (value necessary for Layout definition). The transmission is con-
sidered adequate if the load is applied to a maximum distance a=40 mm from the shaft shoulder (PTO) as shown in
fig. 12.
For dimensions differing from those specified above, contact our Customer Service Department.
