The new range of Etatron DS Dosing Pumps, the eOne series, represents an important step forward. The eOne technical characteristics deliver a reliable and effective solution for those businesses and customers involved in Chemical Dosing and Water Treatment.
The main common characteristics for all the eOne series (except for the eOne BASIC pump) are as follows:
1. High stroke rate up to 300 impulses/min
2. Flow rate variation control in relation to pressure changes
3. Energy efficient (typically 26W at the maximum load) using absorbed power control in comparison to the real dosing conditions.
This gives the following advantages: • Constant dosing • Energy saving • Low operating temperatures resulting in reduced mechanical/electrical stress and giving increased equipment life cycle and reliability.
4. eOne Dosing Pumps power supply range of 100v….250Vac (50-60Hz) voltage
5. Proportional function. 1÷1 on all manual pumps
6. UNDERLOAD – Suction alarm: in the event of a low chemical level, blocked suction valve or damaged suction line
7. OVERLOAD – Discharge alarm: in the event of overpressure in pump head caused by an obstruction or increased operating system pressure beyond the pump specification - 8. Level control.
Multifunction microprocessor dosing pump, suitable for applications which require proportional dosing. The pump operates at a high dosing frequency (up to 300 impulses/min) and is equipped with a backlit graphic display for correct setting of the various programming parameters. The functions performed by the pump are as follows: • Calibration procedure of the actual impulse injection rate delivered to a specified need • Manual flow rate regulation 0..100 %, 0..300 impulses/min • Proportional mode 1 x n (pulse multiplier), at each signal from the pulse supply emitting meter corresponds “n” injections of the pump, during the injections any following pulses neglected • Proportional mode 1 x n(M) (pulse multiplier with memory), at each signal from the pulse supply emitting meter corresponds “n” injections of the pump, during the injections the following pulses from the meter are memorized and the pump modifies “n” (injections to be delivered) in proportional to the pulses received from the meter during the dosing • 1:n function (pulse divider), at each signal from the pulse supply emitting meter the pump delivers a dosing product injection • ml x I, at each signal from the pulse supply emitting meter the pump delivers a specific amount of the dosing product in “ml” (millilitres), corresponding to the value set during the programming phase • l x I function, at each signal from the pulse supply emitting meter the pump delivers a specific amount of dosing product in “l” (litres), corresponding to the value set during the programming phase • ml x m3 function, at each signal from the pulse supply emitting meter which indicates the transition of l m3 of fluid, the pump delivers a specific amount of dosing products in “ml” (millilitres), corresponding to the value set during the programming phase • ppm function, the dosing pump makes the necessary calculations and doses the exact amount of ppm (parts per million) set during the programming phase • mA function, the pump doses in a proportionally to the current signal (usually 4..20mA) riceived by a flow meter or another connected device • timer/ programmer function • UNDERLOAD – Suction alarm • OVERLOAD – Discharge alarm • Flow sensor alarm – the activation of this alarm indicates an injection failure. A Flow Sensor, located on the discharge side of the pump head, has not detected a predetermined number of injections despite the activation of the electromagnet • Alarm for too many pulses from the supply pulse emitting meter – this is activated when the set parameters, in the functions “1 xn(M)” and “ppm”, have been exceeded from the supply pulse emitting meter. The user must restore the correct setting of the dosing pump • Level control setting (supplied without probe) • Relay output for signalling the alarm status.
