- Use compatible hoses. Respect the diameters described in this manual. Using a too soft hose can cause the obstruction of the suction power.
- Suction: minimum diameter 1" · best diameter 1 1/4"
- Delivery: minimum diameter 3/4" · best diameter 1"
- Fit a diesel fi lter in the suction hose.
- CHECK VALVE: For suctions of more than 2.7 m in depth, with or without meter, it is required a check
valve. It is always advisable to install a check valve according to the pipe diameter.
Equivalent height of the maximum suction: 4 m for diesel. (This equivalence is the vertical distance
from the bottom of the suction tube to the pump inlet tube plus the wastages due to the friction in the
vertical and horizontal route of the tube, the elbows etc.). The top depression levels will affect the fl ow,
cause the accelerated fatigue of the pump and the possibility of cavitation will drastically increase.
- For a suction height higher than 2.7 m or for a horizontal suction length of 10 m, it is necessary a
suction tube higher than the pump admission hole, i.e. 1 1/4".
- RECOMMENDATION: If the delivery hose has a length higher than 5 m in a supply kit, it is advisable
to install a non-return valve in the pump outlet or the meter in order to avoid any overpressure in the
pump retainer or the meter. Make sure the valve is installed in the correct way.
- When lengthening the electricity cable, its cross-sectional area must be increased. Otherwise, the motor can be damaged. Do not make "connections" in the electricity cable.
Periodically follow the below steps so that the pump remains in its best state:
6.1. The IRON-50 230 VAC pumps have an extractable fi lter on the suction in order to avoid the solid impurities input into the pump and/or the meter. The absence of these impurities
means the long life of the pump.
6.2. Check the fi lter in order to see whether there are any stored waste.
2,7 m
5 m
10 m
P: 2,2 bar
4 m
5. CORRECT PUMP USE
5.1. When switching on the pump, the pump motor starts working, self-suctioning the liquid and when opening the nozzle, the diesel transfer will start.
5.2. When the refuelling is fi nished, turn off the pump switch.
5.5. The pump use under extreme conditions can cause an increase of the motor temperature, causing its stop because of the thermal motor protection.
Turn the pump off and wait until it gets cold. Then, the thermal protection will be deactivated.
6. MAINTENANCE
7. REPAIR
ATTENTION
Clean carefully the suction and discharge holes, removing the dust or original packaging material.
Check the sealing liquids or Tefl on go into the pumps. Otherwise the pump or the bypass can be blocked.
ATTENTION
Never use hydraulic pressure adapters for the connections.
These adapters are too narrow, decreasing the fl ow and the pump life.
The installer is the responsible of using the required accessories for the good operation of the kit. The inadequate use of accessories can contaminate or
damage the pump or people.
5.3. IMPORTANT
DO NOT FORGET TO STOP THE PUMP USING THE SWITCH, once the refuelling operation is fi nished. In the event of closing the liquid way through the nozzle,
the liquid freely runs through the bypass of the pump inner. The kit can be damaged.
The pump cannot work in bypass (closed nozzle) during a period higher than 3 minutes because, otherwise, the pump will be seriously damaged. Do not start
the pump without liquid in its inner.
5.4. IMPORTANT
As the pump has worked with the nozzle closed, there is an overpressure in the hose. WHEN STOPPED THE MOTOR, IT IS ADVISABLE TO OPEN THE NOZZLE in
order to allow the discharge of the pressure accumulated in the hose
6.3. Check the hose and the nozzle in order to see whether these are worn or broken. The damaged hoses or nozzles can be a potential risk and/or attempt
against the environment.
- Seal the hose connections of the hoses or pipes with Tefl on or compatible seal liquid. Any air inlet through the suction tube will cause the pump does not suction. Make sure the
leak absence.
- The elbows can cause a fl ow leak. Install the minimum ones the installation requires in order to avoid a charge loss.
- The elbows, unions and connections must have an inner diameter equal or higher to the diameter of the installed pipe. Reducing the diameter diminishes the fl ow and can cause a
breakdown in the motor.
- Fitting a microfi lter in the pump suction will avoid many breakdowns because of the impurities and the long-term of your pump. You will also avoid problems in your vehicle or
machinery injectors when installing an FG-100 microfi lter.
Refer to:
Check valve + York Base fi lter
FUP-1 fi lter · code 66030
FG-100 microfi lter · code 39023
- Using the «silent blocks» pump installation, the vibration noise will be reduced.
- The IRON-50 230 VAC pump can use manual and automatic nozzles. WHEN USING NOZZLES, THE FLOW WILL BE REDUCED BETWEEN 7 and 14 %.
- In case that the pump does not suction during its installation:
Immediately stop the pump.
Check the suction tube is well-sealed (there is not any air inlet).
Check the recommended height or length of the suction tube are not exceeded.
If you are using an automatic nozzle, it is possible there is an air chamber in the delivery line. The air evacuation can be diffi cult because of the automatic stop device that holds
close the valve when the pressure is too low. If so, disassemble the nozzle, start the pump until the liquid fl ows. Then, assemble again the nozzle.
Refer to the next section "PROBLEM GUIDE".
We have got customized ACCESSORIES for each type of pump allowing the rapidity and neatness of the installation both in the suction and in the delivery.
- The suction reels have special injected self-screwing sealing joints, assuring a total sealing.
- The delivery hoses clamped with brass adapters have injected self-screwing joints of its total sealing, not being necessary sealing liquids or other elements.
- The PP telescopic tubes with built-in fi lter do not have impurities in their inner, allowing getting the recipient bottom. (To specify sizes).
The authorized repair workshops are the only ones that can repair the damaged motors. Clean and drain the pumps before sending them.
If a pump is used, by mistake, with fl uids not derived from diesel, this must be rinsed as many times as necessary, enclosing a note where it is stated which fl uids have been pumped.
The pumps, which do not have this specifi cations, will be admitted neither in the workshop nor in the factory.
When ordering spare parts, make sure of giving the spare part code, its description and its serial number. This will guarantee the correct supply of the required part.
