ELECTRONIC
PUMPS
All the electronic pumps possess microprocessor technology. The pump is
continuously measuring a voltage, which in turn determines the mode of
operation, within the hydraulic preset characteristics of it.
There are three series of electronic
pumps, namely the F, G and C series.
"F" series electronic pumps are
designed to inject small volume of chemicals accurately; (0.03L/hr to
10L/hr).
"G" series
electronic pumps are designed to inject chemicals accurately from
1.0L/hr to 30L/hr.
"C" series
electronic pumps are suitable to inject chemicals accurately within
20L to 60L/hr.
Please refer to following
pictures:
Each series of pump has
different models for various types of application.
The models available in
analog pumps are :
|
Model |
Main
features and characteristics |
|
CO |
Constant flow, On/Off mode; injection frequency adjustment
0-100% |
|
CL |
Same as CO mode with additional level control and level
switch with coaxial cable. |
|
PV |
Proportional mode divider (1:n) to external voltage free
contact (turndown ratio 1-1000) |
|
PVM |
In addition to the PV model, step-up mode (multiplier, 1xn)
and divider mode (turndown ratio 1-1000) |
|
IC |
Proportional response to an external analog signal: avalable
at 0-20mA or 4-20 mA. |
|
TE |
Timer pump with start-up
signals, not available in C series |
|
CE |
Constant flow, On/Off mode; injection frequency adjustment
0-100%, only available in F series |
The models available for
digital pumps are :
|
Model |
Main
features and characteristics |
|
MAN
|
constant flow, level control, stroke frequency % rate,
stroke/min, stroke/hour. |
|
EXT
|
proportional mode to external
mA, mV or V signal;
proportional mode divider (1:n) and multiplier (1xn) of
external pulses without pacer. |
|
EXT
RS-485 |
same as EXT,
in addition RS 485 connection for remote control. |
|
RH
|
driven by built in
redox meter (mV) proportionally. |
|
CD
|
driven by built in conductivity meter; proportional
mode, only available in F series. |
|
EN
|
with internal weekly timer, eight daily
programs, only available in F series. |
|
PH
|
driven by built in ph
meter proportionally. |
