• The machine integrating the pump must be made in such a way as to ensure conformity with the safety
requirements indicated in the European Directives. This fact is guaranteed by CE markings and by the
Declaration of Conformity of the Manufacturer of the machine integrating the pump.
• Adequately protect the moving parts using suitable protection devices. Special attention must be given to pulley
applications.
• Install the pump in a place with safe accessibility for cleaning and maintenance. Clean up any water flows produced
by leaks, drainage, pipe maintenance, etc..
• The pump must be installed and allowed to operate horizontally (max tilt angle 3°÷5°).
• The pump must be stably fastened. The supporting surface must be flat and strong enough to avoid any misalignment
between the pump and the motor and any vibrations during operation. To fasten the pump, use the four supporting
studs in the pump crankcase. For sizes refer to Fig. 3.
• Being of the positive-displacement type, the pump must always be equipped with a pressure unloader/regulation valve
and with a pressure relief valve.
CAUTION
• Perform correct motor-pump alignment. Special attention must be given to pulley and flexible coupling drives
(max acceptable angle discrepancy 3°).
• In case of pulley application, it may be necessary to reduce the allowed performances. In those cases please
contact the Manufacturer's After-Sales Service. The pulley drive is allowed only for versions without gearbox.
• Keep to the exact direction of rotation as indicated in the illustration (Fig. 1):
• Pump application must be such that during operation, an oil temperature of 80 °C/176 °F is never exceeded.
• In case the pump is painted on the outside, protect the PTO (oil guard included) and water drainage holes, located
on the cover (12) on the crankcase (see figures 6 and 7).
For the main dimensions, refer to Fig. 3.
The Manufacturer's After-Sales Service is at the disposal of Skilled Technicians to provide all related information:
• to identify the most suitable application and its correct execution;
• as regards the precautions to be adopted in the event of continuous operation being required;
• as regards particularly heavy-duty use.
The pump applications must, in any case, be performed according to the best rules of mechanical engineering.
