Priming
Before commissioning the pump, air in the
pump head should be bled.
For this, attach the PVC hose that you can find
among the accessories to the air bleed union on
dosage pump, whose assembly and wiring should
be completed beforehand, and then send the output
to chemical tank
Loosen the air bleed union.
Start the pump.
Check whether chemical is resupplied to the
thank from the hose connected to air bleed union.
Priming is over.
Close tight the priming union.
This cannot be manually done in models
equipped with automatic priming feature.

Operation
18
11 Operation
Your dosage pump operates with a
Teflon (PTFE) diaphragm connected to an
electromagnet driven with a direct current. When
electromagnet pulls the piston, pressure is
generated on pump head and released from
dosage liquid output valve in a pressurized
manner.
Once electricity pulse is interrupted, a spring
brings back the piston and liquid enters through
input valve.
Easy to use and no need for pump oiling.
Consequently, it's maintenance-free.
Materials in pump body are specially
manufactured to protect against toxic and acidic
substances.
Pumps have been manufactured in various
capacities to operate under max 20 Bar pressure
between 0 and 20 lt/hour.
Pump capacities are easily adjustable through
capacity control pots on them in analogue models.
Digital Model Pump Details
You can adjust pump capacities of digital models
from the parameters using the buttons on them
easily. Parameter settings are given in detail in
following pages.
You can mount Liquid Level Sensor to BNC socket if
needed. If Liquid Level Sensor has been installed,
pump will stop operating once the liquid in the
chemical tank is consumed up. If the model has
pump alarm output feature, it activates alarm output
tips and the warning system.
There is no major difference between analogue and
digital models with respect to installation.
