Outlet duct
With a flow rate of ~ 170 l/min and a water velocity of
5.5 m/sec. The graph line joining the two scales meets the
central scale showing the diameters, corresponding to a value
of ~ 30 mm.
Optimal speeds:
-
Suction:
≤ 0.5 m/sec.
-
Outlet:
≤ 5.5 m/sec.
The graph does not take into account pipe
resistance, valves, load loss produced by the length
of the ducts, the viscosity of the liquid pumped or
the temperature itself.
If necessary, contact our Technical or Customer
Service Departments.

V-belt transmission
The pump can be controlled by a V-belt system.
For this pump model, we recommend to use No. 4 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 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 definition). 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 differing from those specified
above, contact our Technical or Customer Service
Departments.
