<h3 style="text-align: left;">Introduction</h3>
<p style="text-align: left; font-family: Arial; font-size: 10pt;">STAR pumping stations collect water in a tank in order to evacuate it with a pumping unit.</p>
<p style="text-align: left; font-family: Arial; font-size: 10pt;"><strong>2 regulation systems :</strong></p>
<ul style="margin-left: 5%; text-align: left;">
<li>
<p style="font-family: arial,helvetica,sans-serif; font-size: 10pt;">Ball switch float</p>
</li>
<li>
<p style="font-family: arial,helvetica,sans-serif; font-size: 10pt;">Aero performance</p>
</li>
</ul>
<p style="text-align: left; font-size: 10pt; font-family: Arial;">TECHNEAU offers 2 ranges of pump stations STAR :</p>
<ul style="margin-left: 5%; text-align: left;">
<li>
<p style="font-size: 10pt; font-family: Arial;">Polyethylene</p>
</li>
<li>
<p style="font-size: 10pt; font-family: Arial;">Polyester</p>
</li>
</ul>
<h3 style="text-align: left;">Standards</h3>
<p style="text-align: left; font-size: 10pt; font-family: Arial;">All stations meet the regulatory requirements of the standard NF EN 12050 and are supplied with a certificate of conformity initial type (test report) issued by the authorized body CSTB.</p>
<h3 style="text-align: left;">Operation</h3>
<p style="text-align: left; font-size: 10pt; font-family: Arial;">Pump switching on and off is triggered by the water level in the pumping tank (level is controlled by a ball switch float or pressure measuring device).</p>

<h4 style="text-align: center;">With 1 pump</h4>
<p><img style="display: block; margin-left: auto; margin-right: auto; width: 75%;" title="Operation with 1 pump" src="images/relevage/star/STAR_installation_1_pompe_UK.png" alt="STAR installation 1 pompe UK" /></p>
<p style="text-align: left; font-size: 10pt; font-family: Arial;">Water rises in the tank and reaches level one, a level sensor switches the pump on, water backs down and reaches thlevel 2 where the detector stops the pump.</p>
</td>
<td class="bloc_50_gris">
<h4 style="text-align: center;">With 2 pumps</h4>
<p><img style="display: block; margin-left: auto; margin-right: auto; width: 75%;" title="Operation with 2 pumps" src="images/relevage/star/STAR_installation_2_pompe_UK.png" alt="STAR installation 2 pompe UK" /></p>
<p style="text-align: left; font-size: 10pt; font-family: Arial;">The operation is the same as with one pump, but the control panel commands the two pumps to work alternatively :</p>
<ul style="text-align: left; margin-left: 5%;">
<li>
<p style="text-align: left; font-size: 10pt; font-family: Arial;">1st cycle = 1 pump;</p>
</li>
<li>
<p style="text-align: left; font-size: 10pt; font-family: Arial;">2nd cycle = pump 2.</p>
</li>
</ul>
<p style="text-align: left; font-size: 10pt; font-family: Arial;">In case of malfunction of one of the two pumps, or in case inflow higher than that of the working pump (level 3 is reached), the level detector will trigger the second pump. The non return valve is a device that prevents the return of water from the discharge pipe.</p>
