CAUTION !
THE PUMP CANNOT STAND PRESSURES HIGHER THAN THOSE INDICATED ON THE RATING PLATE.
• With pump not running, check the oil through the oil window (for oil type see table F).
• Check the electric connections and also the direction of rotation of the motor (shown by the arrow on motor body).
• Make sure that all on-off valves on the suction and discharge pipelines are open.
• Make sure that the liquid to be metered has not solidified or frozen inside the piping.
• Carry out the first startup with discharge pressure as low as possible and with adjustment knob set to 20%; keep these conditions
about 3 ÷ 5 minutes. Increase gradually the flow rate up to the maximum value, then set the pump to the required working conditions
(flow rate and pressure).
• During the first stage check the pump discharge pressure by means of the pressure gauge: the pressure value (max. oscillation of the
pointer) must not exceed the max. pressure indicated on the pump rating plate.
THE STARTUP HAS TO BE DONE AS FOLLOWS:
STARTUP
• Make sure that the baseplate is made of steel, stable and even. Do not install the pump directly on a concrete foundation.
• Fix the pump to the baseplate using the specific anchor holes in the pump feet.
• Make sure that the pump valve axis is perfectly upright.
• Before connecting the piping to the pump, it is absolutely necessary to flush the pipelines with water, especially the suction line and
relevant feed tank.
• The pipelines must be independently supported, so as to prevent stresses on the pumphead. Therefore, besides the baseplate, the
pump needs a supporting framework for both suction and discharge pipelines.
• It is recommended to fit a cross after the discharge flange. This fitting will facilitate the removal of the pump from the baseplate and
can be used for the installation of pressure gauges, safety valves and dampeners.
• Make sure that the pipeline fittings and flanges are perfectly tight and in particular that no air enters the suction line, as this would
hinder the priming of the pump.
This preliminary flushing is often underestimated by the installator; if this operation is not
properly carried out, the pump will become a collector of all foreing matters contained in
the pipeline and tank, such as weld drops, gasket scraps, soil and other stuff.
