SAFETY DATA
ATTENTION
Use of toxic or hazardous agents:
•All requirements for mitigating the risks caused by composition of
hazardous and toxic agents are provided in this manual.
•Refer to the manuals provided by the manufacturers of the
dosage fluid.
•Examine the hydraulic components of the pump, and use only if
they are in proper condition.
•Use only appropriate materials for piping, sleeve, suction and
discharge valves. PVC pipes can be more proper.
•Read the notes 1, 2 and 3 onthis pageto remove the pump. Refer
to the “MAINTENANCE” section to relive pressure and vent the

GENERAL WARNINGS
ATTENTION
•The air in the pump head must be vented prior to commissioning of
the pump.
•Securely fit the air vent sleeve after completion of the air venting
operation. It is not necessary to remove the air vent hose. If the air
vent sleeve is left loose, the chemical shall not move through the
discharge line.
•Install the pump at a dry place away from any heat source where the
ambient temperature does not exceed 40 ºC.

2. For this purpose, fit thePVC hoseamong the accessories to theair vent sleeve
on the dosage pump with assembly and electrical connection completed, and
place the discharge end of the hose to the chemical tank.
3. Loosen the air vent sleeve.
4. Start the pump.
5. Ensure that the chemical goes back to the tank through the hose connected to
the air vent sleeve.
6. So the air vent operation is completed.
7. Tighten the air vent sleeve securely.
8. This operation is not performedmanuallyfor the models with automatic air vent.

Operation

5Operation
The dosage pump operates with a diaphragm (PTFE) connected to an electromagnet
driven by direct current. When the electromagnet pulls the piston, an amount of pressure is
generated in the pump head, and the pressurized dosage liquid goes through the discharge
valve.
•When the electrical pulse is interrupted, a spring brings the piston back to the position and
the liquid fills through the intake valve.
•It is easily operated, does not require lubrication. Therefore it does not require any
maintenance operations.
•The materials used in the pump body are specially produced so as to be resistant against
toxic and acidic materials.
•Pumps are designed to be operated with max 20 Bar pressure and 0 to 20l/h flow rate.
•Pump capacities can be easily adjusted by means of the capacity control pots on the
analog models.
5.1 Description of the Analog Model Pumps
Pump capacities of the analog models can be easily adjusted by means of the
potentiometer on the pump. A liquid level sensor can be installed in order to cease operation
of the pump when the liquid in the chemical tank reaches down to zero level.
