9.10 V-belt Transmission
The pump may be driven by a v-belt system. For this pump model, we suggest using 4 XPB belts (16.5x13 cogged); for
long durations, use the XPC profile; both the characteristics and the power transmission capacity of each belt can be
verified on the diagram in fig. 8, in function of the number of rotations normally declared by the manufacturer. Minimum
diameter of the driven pulley (on the pump shaft) ≥ 9.8 in. (250 mm). The radial load on the shaft must not be greater
than 7500 N (value required for the definition of the lay-out). The transmission is considered adequate if this load is
applied at a maximum distance of a=40 mm from the shaft shoulder (PTO) as indicated in fig. 11.
The diagram does not take into account the hose and valve resistance, the pressure drop due to the pipe length,
the viscosity and the temperature of the pumped fluid. If necessary, contact our Customer Service Department.
For sizing that differs from that indicated above, please contact our Customer Service Department for
assistance.
