To obtain priming, proceed as follows:
KVC – KVCX (Fig.5) :
 After having removed the cap, fill the pump slowly through the filling hole so as to discharge any air pockets
present inside.
NKV (Fig.6) :
 Before filling the pump through the filling hole you must first partially unscrew the drainage pin/cap without
forcing it.
 After having removed the cap, fill the pump slowly through the filling hole so as to discharge any air pockets
present inside.
 Before starting the pump, close the filling cap and screw the drainage pin/cap all the way, without forcing it.

Vent by means of the screw on the part opposite the filling cap, as indicated in Fig. 6.

Fig. 6 NKV
 Fully open the gate valve on intake and keep the one on delivery almost closed.
 Switch on and check that the direction of rotation is correct, as indicated in Fig. 1. If not, invert any two phase
leads, after having disconnected the pump from the power mains.
 Once the hydraulic circuit has been completely filled with liquid, gradually open the delivery gate valve until its
maximum opening.
 With the pump running, check the supply voltage at the motor terminals, which must not differ from the rated
value by +/- 5%.
 With the unit at regular running speed, check that the current absorbed by the motor does not exceed the value
on the data plate.
