Thank you for visiting the Pumptron Web site.
most common question we are asked about Pumptron is:
Should I use Pumptron Instead of a Conventional Controller?
answer is quite simple:
eliminates the need for probes to detect water levels, also flow valves and
pressure valves to detect water flow, devices that are expensive and proven to
be unreliable, consequently Pumptron significantly reduces the cost and
simplifies the overall installation providing high reliability
reason being conventional Borewell Pump Controllers have
sensors that control the Pump, over time these sensors
develop a build up of mineral deposits
and other materials. If the Borewell is dry, and water drops on the sensors from
higher in the Bore, the controller can turn the pump on.
As the Bore
replenishes itself the pump can still be turning, this then makes the pump
cavitate, until such time that there is enough water in the Bore to "break
through the cavitation effect"
The result of this is that, the motor
is pumping dry, which can destroy the pump and damage the
turbine.. This is especially the case if this
is repeated which is frequently the case. What has been needed is an intelligent
controller that knows if the pump is pumping “Air”.
Pump Controllers may not detect a
failed phase which can also damage the pump.
The cost of withdrawing the pump,
having it replaced and having it replaced in the bore can cost 6,000 Euros.

is an Australian designed and manufactured
state of the art electronic device
for the protection and control of Submersible water pumps or any
other applicable pump installation. Pumptron is the product of a research
and development program (R&D) that lasted for more than six years of
investigation in the field. It is a simple, cost effective
protection and control unit that does away with the need for flow switches or pressure switches
immersed into the well or bore, which are expensive to install and tend to be

simple. Power from the main is connected to Pumptron’s input. The output
is connected to the pump. Pumptron can be installed next to the bore or
far away… even kilometres if necessary!
needs to be set up only once to suit the particular pump.
A small adjusting screw is turned until a green light
shows that the pump is being detected and under protection and control.
Once the pump
is started it will run continuously until water is no longer available.
Pumptron senses this and stops the pump. Pumptron’s timer then starts
to measure a pre selected time period (set according to the bore water productivity)
to allow the bore to refill. This recovery time can be set between 3 minutes and
selected recovery time lapses, the pump turns ON automatically and runs until
the water is exhausted again. If water is still not present after the pre-set
recovery time has elapsed Pumptron will start and stop the pump after ten
seconds. This “wait for recovery time/try to pump” sequence will repeat until
water is present.
The pump is
automatically controlled and protected in this manner until Pumptron is
switched OFF manually using the ON/OFF switch on the front panel.
If the pump
overloads for any reason, Pumptron will immediately remove power. A flashing red warning light indicates that an overload exists and the
system is halted. Pressing the Start/Reset button,
or at the water recovery time lapse, Pumptron will check; if the overload condition is still
present, the system will instantly return to the
Stand By condition and the
warning light continues to flash. Call
for service as there may be mud or
other agents causing the overload. On the other hand if the overload condition has
disappeared, normal operation is resumed.
When a pump is used to fill a tank or a dam, a plug (connector supplied) is
available to connect to a float switch or any external switching device. While
Pumptron will maintain its operation of control and protection, the switch
indicates when the tank or dam has reached the desired level and the unit stops.
When the water level drops and the switch turns ON the pump starts again.
The system remains absolutely automatic and unattended.
TECHNICAL - UNIQUE FEATURES:

done at the ZERO voltage cross over point of the AC. Pumptron detects
when the AC sine wave is at zero volts and trigger the switching thyristors only
at that point of time. This results in shock free switching thus providing
protection to starter capacitors (condensers) and to the system itself.
light beam is used in the switching process. This provides high isolation between the low voltage electronics and the main, making
Pumptron very safe to use.
