APPLICATIONS

These electro pumps find use systems for lifting water from wells, first collection tanks or cisterns, streams, to basement pump out (cellar, garages), to swimming pools pump out and small agricultural installations, sprinkling systems for gardens and allotments. When installed in wells or tanks, the pump, which is particularly silent running, avoids all problems related to suction and loss of priming.
The pump may be supplied with a float switch cutting out operation automatically in the event of an insufficient water level.
These pumps cannot be used in swimming pools, ponds or tanks in which people are present, or for pumping hydrocarbons (petrol, diesel fuel, fuel oils, solvents, etc.) in accordance with the accident-prevention regulations in force.
N.B. : The liquid employed in the pump for lubricating the sealing device is not toxic, but it could alter the water properties (in the case of pure water) if there were any leaks in the seal.

PUMPED FLUIDS

The machine has been designed and built for pumping water, free from explosive substances, and solid particles or fibres, with a density of 1 Kg/dm³ and a kinematic viscosity of 1mm²/s, and chemically non-aggressive liquids.

INSTALLATION

7.1 SITE OF INSTALLATION

  • Before immersing the electro pump in the pit or tank, ensure that the place is free from sand or solid sediment.
  • In case there is sediment, accurately clean the site where it is to be placed.
  • Keep the pump at least 1 mt. raised above the bottom of the pit so that any deposits that form after installation will not be sucked up.
  • Remove the sediment periodically.
  • It is very important to ensure that the water level never falls below the body of the pump.

7.2 WORKING CONDITIONS

  • Water temperature: from 0°C to +50°C.
  • Pump body always completely immersed.
  • The pump cannot operate dry.
  • Installation in vertical or horizontal position.
  • The housing pit must be frost-free.
  • Maximum depth of immersion 5 mt. (below water level).

7.3 PIPING

  • The hydraulic connection of the pump may be made with iron or plastic parts, either rigid or flexible.

  • Avoid any kind of choking of the output pipe.

  • It is advisable to use pipes with an internal diameter at least equal to that of the delivery pipe, so as to avoid a fall in the performance of the pump and the possibility of clogging.

  • For the version with a float switch, ensure that the latter can move freely (see Paragraph 9.2.
    “REGULATING THE FLOAT SWITCH”).
    The size of the pit must always be calculated in relation to the quantity of incoming water and to the flow rate of the pump so as not so subject the motor to an excessive number of starts.

  •  To lower the pump, always use a rope or chain fixed be forehand to the upper handle on top of the pump.
    Never use the power cable to lift the electro pump.

  • When using in deep wells, it is advisable to secure the power cable to the delivery pipe with clamps, every two/three metres.

WARNING! The pump should not be run dry! It should be put fully into the liquid to be pumped.
Slurping for long periods should be avoided.
**** The length of the power cable on the electro pump limits the maxi mum depth of immersion at which the pump may be used.

ELECTRICAL CONNECTIONS

CAUTION! ALWAYS FOLLOW THE SAFETY REGULATIONS!
8.1 The electrical installation must b e carried out by an authorized and competent electrician who assumes all the responsibilities.
8.2 Ensure that the mains voltage is the same as shown on the plate of the motor to be fed and be sure TO MAKE A GOOD GROUND CONNECTION.
8.3 The electro pump, both the single-phase and the three-phase version is supplied with an
electric cable. If the power cable is damaged in any way it must be replaced, not repaired.

  • It is advisable to connect the pump to a dedicated power line.

  • Upstream from the pump, fit a suitably sensitive magnetothermal differential switch.

  • Switch off the power upstream from the system before making the electrical connection.

  • Single-phase motors are provided with built-in thermal overload protection and may be con nected directly to the mains.
    Warning: If the motor is overloaded it stops automatically. Once it has cooled down it starts again automatically without requiring any manual intervention.

  • Three-phase pumps must be protected with motor protectors suitably calibrated according to the values on the data plate of the pump to be installed.

  • Connect the pump cable to the electric panel, ensuring that the following parts correspond:
    SINGLE PHASE

  • Before making a test start, check the water level inside the well.

8.4 CHECKING THE DIRECTION OF ROTATION (for three-phase motors)

Fig.2 CAUTION! ALWAYS FOLLOW THE SAFETY REGULATIONS
The direction of rotation must be checked each time a new installation is carried out.
Proceed as follows:

  1. Place the pump on a flat surface.
  2. Start the pump and stop it immediately.
  3. Carefully observe the kick-back on starting, looking at the pump from above. If the direction of rotation is correct, the upper cap will turn counter-clockwise as indicated by the arrows in the drawing (Fig. 2).

If it is not possible to check as described above because the pump is already installed, check as follows:

  1. Start the pump and observe the water flow rate.
  2. Stop the pump, switch off the power and invert two phases on the supply line.
  3. Restart the pump and check the water flow rate again.
  4. Stop the pump.
    The correct direction of rotation is the one that gives the higher flow rate.

9 START-UP
9.1 Turn the differential magnetothermal switch upstream from the pump to position I (O N) and wait until the water comes out of the delivery pipe.
If malfunctions are found, disconnect the pump from the power supply, turning the differential magnetothermal switch to position 0 (OFF) and consult the chapter 13 on “TROUBLESHOOTING”.

  • The pump may be started and stopped:
    – Manually by means of the differential magnetothermal switch upstream from the system.
    – Automatically when water level rises, for versions with a float switch.

9.2 FLOAT SWITCH SETTING
By lengthening or shortening the stretch of cable between the float and the fixed point (Float locking) it is possible to regulate the level at which the pump switches off. Ensure that the float witch can move freely when the pump is operating. Make sure the stop level does not uncover the filter.

PRECAUTIONS

  • The suction filter must always be present when during pump is operating.
  • The pump must not be started more than 30 times in one hour so as not to subject the motor to excessive thermal stress.
  • DANGER OF FROST : When the pump remain s inactive at temperatures of less than 0°C, it is necessary to ensure that there is no water residue which might freeze, and cause cracking of the pump components.
  • If the pump has been used with substances that tend to deposit, rinse it after use with a powerful jet of water so as to avoid the formation of deposits or scale which would, tend to reduce the pump characteristics.

MAINTENANCE AND CLEANING

In normal operation the pump does not require any type of maintenance, thanks to the oil bath lubricated seal and to the greased-for-life bearings.
**** The electro pump can only be dismantled by skilled and qualified personnel, in possession of the technical qualifications required by the specific regulations in force.
In any case, all repair and maintenance jobs must be carried out only after having disconnected the pump from the power mains, once made sure that it cannot suddenly begin working. During dismantling it is necessary to pay great attention to sharp parts which may cause injury. The cutting edge flange of the electro pump is provided of aspiration fans. It is advisable, every now and then, to clean these fans to avoid a loss of efficiency. Best cleaning is obtained through a throw of water. Sand and other abrasive materials cause precocious wear and tear, as well as loss of performances.

MODIFICATIONS AND SPARE PARTS

Any modification not authorized beforehand relieves the manufacturer of all responsibility.
**** All the spare parts used in repairs must be original.
All accessories must be approved by the manufacturer so as to be able to ensure maximum safety of the machines and systems in which they may be fitted.
