Multifunctional metering pump eONE PLUS

EONE PLUS multi-function proportional metering pump with integrated PH-RX-CL controller

  • Productivity: 1 ÷ 30 l/hour.
  • Pressure: 0.5 ÷ 20 bar .

The eONE PLUS proportional metering dosing pump with a PVDF head is a compact manual pump for dispensing liquid reagents of any chemical composition. With its vast selection of features, this state-of-the-art digital dispenser is the flagship of the Etatron solenoid pump range. It is implemented on the basis of a microelectronic circuit that “intelligently” controls the solenoid, adjusting power consumption and supply according to the backpressure fluctuations in the system.

The dosing pump eONE PLUS operates manually, or in a proportional dosing mode according to the level of pH (acid/base balance), RedOx (redox potential Rx) and free chlorine (Cl), from signals (pulses) of an external flow meter, from 4-20 mA signal, as set by ppm.

Dosage regimens:

- Manual « Manual » . The pump doses in a constant ON/OFF mode, the performance is regulated by the frequency of pulses (injections) in the range from 0 to 180 pulses/min or from 0 to 100%.

- Proportional « PROP » . In this mode, the manufacturer offers a wide selection of functions.

  • Dosing according to pH, RedOx, Cl water level. The pump is equipped with a built-in controller, when programming you must select one of the measured parameters: pH, Rx or Cl. Ranges of level measurement: pH 0-14 with a resolution of 0.01 pH, Rx from -1000 to +1400 mV with a resolution of 1 mV, Cl 0-20 ppm with a resolution of 0.1 ppm.
  • Dosing according to signals from an external flowmeter. For each flowmeter signal, the pump supplies a certain portion of the reagent. The number of servings of the reagent is set by choosing the function:
    « 1xN » - for 1 signal of the flow meter, N pump pulses are issued
    « 1xN (M) » - NxM pump pulses are given per 1 flowmeter signal, where M is the number of flowmeter signals in memory
    « 1: N » - 1 pump impulse is outputted to N flowmeter signals
    « 1 x ml » - a preset number of milliliters of reagent is supplied per meter signal
    « 1 x L » - a preset number of liters of reagent is supplied per meter signal
    « ml x m3 » - the specified number of milliliters of reagent is supplied to the number of flowmeter signals corresponding to one cubic meter of water
    The values N, M, ml, L are entered by the user.
  • ppm mode (millionth of a share). This mode is used when you need to dose very accurately.
    Through the menu, the parameters of the signal from an external flowmeter, pulse volume of the reagent,% - reagent concentration and ppm value (from 0 to 20.00) are programmed. Based on this data, the number of pulses per volume of water passing through the flowmeter is automatically determined and set.
  • Dosing by an external current signal with a range from 4 to 20 mA. The pump pulse frequency is proportional to the received mA signal - the larger the signal, the higher the performance.

Additional functions: using a timer, setting the 4-20 mA output, setting the on-delay time, manual or automatic thermal compensation (when the corresponding PT100 sensor is connected).

Installed on/off protection functions , which provide the inclusion of an alarm and can independently stop the pump:

  • « UNDERLOAD » (underloading) - responsible for reagent collection
  • « OVERLOAD » (overload) - responsible for reagent discharge
  • « FLOW SENSOR » - signaling of the output flow sensor, control of the reagent output from the dispenser head
  • « ALARM » - signal about memory overflow (exceeding the number of recorded signals).
  • Productivity up to 30 l/h (500 ml/min) with a back pressure of 5 bar
  • Maximum pulse frequency 180 cpm
  • Electrical parameters: universal voltage 100-250 V
  • Height of reagent intake 2 m
  • Level sensor support (sensor not included).
