4. MANAGEMENT Observe the current accident prevention standards. Risk of crushing. The pump may be heavy. Use suitable lifting methods and always wear personal protection equipment. Before handling the product, check its weight to identify suitable lifting equipment.
4.1 Storage All the pumps must be stored indoors, in a dry, vibration-free and dust-free environment, possibly with constant air humidity.They are supplied in their original packaging and must remain there until the time of installation. If this is not possible, the intake and delivery aperture must be accurately closed. 4.2 Handling Avoid subjecting the products to needless jolts or collisions. To lift and transport the unit, use lifting equipment and the pallet supplied standard (If applicable). Use suitable hemp or synthetic ropes only if the part can be easily slung, connecting them if possible to the eyebolts provided. In the case of coupled pumps, the eyebolts provided for lifting one part must not be used to lift the pump-motor assembly.
The pump motors supplied with eyebolt should not be used to handle the whole assembled electric pump (fig.1C, page 1). For handling pumps with motor of up to 4kW, use the belts wound around the motor as shown in fig. 1A, page 1. For pumps with motor power greater or equal to 5.5kW, use the belts attached to the two flanges, located in the coupling area between the pump and the motor as shown in fig.1B, page 1. There is a risk that the pump may overturn during handling; make sure that the pump remains in a stable position during handling.

5. WARNINGS 5.1 Checking motor shaft rotation Before installing the pump you must check that the rotating parts turn freely. For this purpose, remove the fan cover from its seat in the motor end cover. Insert a screwdriver in the notch on the motor shaft from the ventilation side. Fig. 2, page 1.
Do not force the fan with pliers or other tools to try to free the pump as this could cause deformation or breakage of the pump.

5.2 New systems

Before running new systems the valves, pipes, tanks and couplings must be cleaned accurately.

To avoid welding waste or other impurities getting into the pump, the use of TRUNCATED CONICAL filters made of corrosion resistant

materials (DIN 4181) is recommended.

6. PROTECTIONS 6.1 Moving parts Before starting the pump all the moving parts have to be properly protected with dedicated components ( fan, cover, etc.).
During pump operation, keep well away from the moving parts (shaft, fan, etc.). If getting closed to the running pump is necessary, be properly dressed as from laws rules, in order to avoid injuries.
6.2 Noise level See table A, pag. 105. In cases where the LpA noise levels exceed 85 dB(A), suitable HEARING PROTECTION must be used in the place of installation, as required by the regulations in force. 6.3 Hot and cold parts
DANGER OF BURNING !! As well as being at high temperature and high pressure, the fluid in the system may also be in the form of steam! It may be dangerous even to touch the pump or parts of the system. If the hot or cold parts are a source of danger, they must be accurately protected to avoid contact with them.
7. INSTALLATION The pumps may contain small quantities of residual water from testing. We advise flushing them briefly with clean water before their final installation.
7.1 Pump installation – The electropump must be fitted in a well ventilated place and with an environment temperature not exceeding 50°C.
– If installed outdoors, protect the pump from the weather and direct sunlight. – It is always good practice to place the pump as close as possible to the liquid to be pumped.
16

ENGLISH – The installation baseplate, provided by the customer, if they are metallic they have to be painted rust and corrosion. They have to be
flat and stiff enough to resist to short circuit forces and avoid resonance due to vibrations. – Concrete basements have to be well solid and dry before installing the pumps. – A firm anchoring of the feet of the pump assembly on the base helps absorb any vibrations created by pump operation. – The pump can be installed horizontally with the aid of the appropriate supports or vertically with the motor at the top. – Ensure that the metal pipes do not transmit excess force to the pump apertures, so as to avoid causing deformations or breakages. – Use pipes with a suitable thread to avoid damage to the inserts. – The internal diameter of the pipes must never be smaller than that of the electric pump inlets. – If the head at intake is negative, it is indispensable to fit a foot valve with suitable characteristics at intake. – For suction depths of over four metres or with long horizontal stretches it is advisable to use an intake pipe with a diameter larger than
that of the intake aperture of the pump. – Any passage from a pipe with a small diameter to one with a larger diameter must be gradual. The length of the passage cone must be
5 to 7 times the difference in diameter. – Check accurately to ensure that the joins in the intake pipe do not allow air infiltrations. – To prevent the formation of air pockets, the intake pipe must slope slightly upwards towards the pump. Fig. 4, page 1.
– Interception valves must be fitted upstream and downstream from the pump so as to avoid having to drain the system when carrying
out pump maintenance. Do not run the pump with closed valve on the plant.
– If there is any possibility of the pump operating with the interception valves closed, provide a by-pass circuit or a drain leading to a liquid
recovery tank.
– To reduce noise to a minimum it is advisable to fit vibration-damping couplings on the intake and delivery pipes and between the motor
feet and the foundation. – If more than one pump is installed, each pump must have its own intake pipe. The only exception is the reserve pump (if envisaged). 7.2 Minimum inlet pressure ( Z1 ) (negative suction head pump) To have good performances of the pump avoiding cavitation phenomenon it is necessary to calculate the suction lift Z1. Fig. 5, page 2 To determine the suction level Z1, the following formula must be applied:
Z1= pb rqd. N.P.S.H Hr correct pV Hs where:
Z1 = difference in level in metres between the intake mouth of the pump and the free surface of the liquid to be pumped. Pb = barometric pressure in mcw of the place of installation.(chart 1, pag. 107) NPSH = net load at intake of the place of work. Hr = load loss in metres on the whole intake duct. pV = vapour tension in metres of the liquid in relation to the temperature expressed in °C. (chart 2, pag. 107) Hs = safety margin = minimum 0.5 metres head

If the calculated “Z1” is positive, the pump can operate at a suction lift of maximum “Z1” metres head.

If the calculated “Z1” is negative, than the pump has to be fitted with a positive lift of at least “Z1″ mt. Ex. : installation at sea level and fluid at 20°C

Z1

10,33 3,25 2,04 0,22 0,5 = 4,32 approx.

This means that the pump can operate at a suction lift of maximum 4,32 metres head. 7.3 Minimum suction pressure (positive suction head pump)

It is important to maintain the sum of the inflow pressure and that developed by the pump, the latter with feeder closed, always lower than the

maximum pressure rating (PN) permitted by the pump. P1max + P2max PN (fig.6A, page 2) P1max + P2max + P3max PNHP (fig.6B, page 2) 7.4 Minimum nominal capacity

The function of the pump at a lower level than the minimum permitted nominal capacity may cause excessive and detrimental overheating of the pump. For liquid temperatures higher than 40°C, the minimum capacity should be increased in relation to the temperature of the liquid (see fig. 6A, page 2).

The pump must never operate with the delivery valve closed.

7.5 Electrical connections Scrupulously follow the wiring diagrams inside the terminal board box and those on table C, page 106.

–

Ensure that the mains voltage is the same as that shown on the motor data plate.

–

The pumps must always be connected to an external switch.

17

ENGLISH
– Three-phase motors must be protected with an automatic switch (e.g. circuit breaker) calibrated at the values shown on the data plate of the electropump.
– In the case of three-phase motors with star-delta start, ensure that the switch-over time from star to delta is as short as possible.(see table B, page 106). In electropumps the terminal board may face in four different positions: slacken and remove the four retaining screws between the motor flange and the support. Turn the motor into the desired position and replace the screws.
7.6 Starting In accordance with accident-prevention regulations, the pump must be run only if the coupling (where provided) is suitably protected. So the pump must be started only after having checked that the coupling protections are correctly fitted. To obtain priming, proceed as follows: NKV (Fig.7):
– Before filling the pump through the filling hole you must first partially unscrew the drainage pin/cap (when filling just unscrew it by 3 or 4 turns) 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. 7 – 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. 2, page 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.

7.7 Stopping

ENGLISH

Close the interception device on the delivery pipe. If there is a check device on the delivery pipe, the interception valve on the delivery side may

ramain open as long as there is back.

For a long period of inactivity, close the interception device on the intake pipe and, if supplied, all the auxiliary control connections. 7.8 Precautions

The electropump should not be started an excessive number of times in one hour. The maximum admissible value is as follows:

Type of pump NKV 10
NKV 15 – NKV 20 NKV 32 – NKV 45 NKV 65 – NKV 95

Maximum number of starts per hours 10 ÷ 15
5 ÷ 10

– When the pump remains inactive for a long time at temperatures of less than 0°C, the pump body must be completely emptied through the drain cap.
Check that the leakage of liquid does not damage persons or things, especially in plants that use hot water.

– It is recommended to empty the pump when it is not running for a long time at normal temperature. – The drain plug shall be opened until the pump will be utilized again. – When restarting after long periods of inactivity it is necessary to repeat the operations described above in the paragraphs WARNINGS
and STARTING UP.
8. MAINTENANCE – In normal operating conditions the electropump does not require any kind of maintenance. – It is recommended to check time by time current absorption, pressure head at closed valve and maximum flow. – The electropump can only be dismantled by specialised, skilled personnel in possession of the qualifications required by the specific regulations. – In any case all repair and maintenance jobs must be carried out only after having disconnected the pump from the power mains. If the liquid has to be drained out maintenance, ensure that the liquid coming out cannot harm persons or things, especially in using hot water. The legal requirements on the disposal of any harmful fluids must also be complied with.
8.1 Modifications and spare parts Any modification not authorised beforehand relieves the manufacturer of all responsibility. All the spare parts must be authentic and all the accessories must be authorised by the manufacturer.
Carry out maintenance based on the type of bearing indicated on the technical data plate.
