9.13 Transmission of power from the second PTO
Upon request, KF series pumps can be supplied with an auxiliary PTO on the opposite side to the drive (Transmission
of power from the second PTO).
Transmission can be carried out:
- By means of the V-belt.
- By means of the joint.
Finally, given a distance between pulley centers of 23.6 inches (600 mm) and a load of 75 N at the middle of the
distance, a belt flexion “te” of around .425 inch (10.8 mm) will confirm the correct belt tension as shown in
fig. 12
.
Note 1
: If not differently indicated by the belt Manufacturer, the inspection of the correct tension value, and the related
tension adjustment if needed is to be carried out after at least 30 minutes of operation in order to obtain belt setting. The
best efficiency and maximum belt life is obtained with the correct tension value.
Note 2
: If required, or during normal maintenance, never replace a single belt, but the entire set.

By means of the V-Belt, withdrawable max torque is:
48 ft. lbs. (65 Nm) which corresponds to:
7 HP at 750 rpm;
7.4 HP at 800 rpm;
8.3 HP at 900 rpm;
9.3 HP at 1000 rpm;
11.1 HP at 1200 rpm.
By means of the V-Belt, withdrawable max torque is:
98 ft. lbs. (130 Nm) which corresponds to:
14 HP at 750 rpm;
14.8 HP at 800 rpm;
16.6 HP at 900 rpm;
18.6 HP at 1000 rpm;
22.2 HP at 1200 rpm.
By the means of the V-belt, the transmission is
considered suitable if: belt pull is applies at a max
distance of 0.87 in. (22 mm) from the bend shaft
shoulder fig. 13. Min diameter of pulley to be
used = Ø 3.94 (100).
With transmission by means of the joint, make
sure it is perfectly aligned so that to transverse
forces are generated on the pump shaft.
For applications different from those specified
above, please contact our Technical or Customer
Service Department.
