SELENOID DOSING PUMP TECRA AXL

The innovative Tecra series electromagnetic metering pump with digital drive is a result of NW's 25 years or working closely with our world-wide customers. These multifunctional metering pumps maintain the high reliability that is synonymous with Waterlink quality.
All Tecra series have IP 65 rated enclosure made of Polypropilene reinforced with glass fiber. Thos allow the pumps to be water and impact resistant and corrosion free.

 

Versatile installation as Tecra series pumps allow for 3 fixing possibilities;
• wall mounting with only one fixing point;
• wall mounting with 2 or 4 fixing points;
• base mounting (on tank or existing wall mounting bracket with optional bracket)

 

DUAL FLOW RANGE SCALE

Tekra AXL dosing pump es made with a dual flow rate range scale.
By a simple switch is possible to reduce of 1/10 the maximun dosing pump pulse frequency.

RELIABILITY

All NW pumps are tested using modern technologies; their reliability is assured through use of high quality materials, intensive laboratory tests and life stress tests. Every pumps, is operated 6 hours at maximun speed before the final test.
Test Certificate with pressure/flow rate diagram made under customer specification is available as an option.

 

CONTINOUS OPERATION

The pumps require only the electrical power supply to work. Flow rate is adjustable through the knob on the front of the pump by changing the number of strokes per minute from 0 to 400.
