START UP

CAUTION: the pump must not be started without previous filling. Dry running can damage the me-
chanical seal and the bearings.
Pump under pressure (see figure 1.A and figures 3.A and B)
1 - Close the gate valve on the discharge side of the pump in order to avoid the loss of the fluid that is being used
to fill the pump.
2 - Remove the upper drainage plug (see fig. 3.A) and slightly unscrew the by-pass valve (see fig. 3.B) in order to
let the two internal chambers of the pump communicate and ease filling. Do not completely remove the by-pass
valve; unscrew it 3 or 4 turns during the filling phase. It is removed only and exclusively to empty the pump.
3 - Open the gate valve located on the pump suction side in order to let the fluid come out on the pump. Make sure
that the difference in level between the pump and the valve assures a complete filling of the pump.
4 - When there is a uniform consistent flow from the drainage cap close it again carefully. Close the by-pass valve.
5 - Check the motor rotation direction as indicated on the pump.
6 - Start the pump and check that it rotates in the right direction.
7 - Open the gate valve slowly on the discharge side until fully open.
Pay particular attention to point 3 in case the pump is filled with hot or hazardous liquids, since the fluid coming out
of the upper drainage cap may contact anyone nearby. Make sure you are in a safe position during this operation.
Close the gate valve after the outcome of a constant liquid flow from the cap before closing it again in order to
avoid contact with the liquid.
Pump in suction (see figure 1.B and figure 3.A, B and C)
1 - Close the gate valve on the pump discharge side in order to prevent the flow in the circuit of the fluid that is
being used to fill the pump and open the gate valve on the suction side.
Rotating parts can catch hands, feet or clothing.
Stay clear of equipment and keep shields in place while pump is running.
Stop motor before servicing pump.
Read owner's manual before using equipment.
