Instead of pumping water up, water is let in from the top. Gravity pulling the water down makes the turbine rotate. The shaft of the screw is attached to a generator which transforms the motion into electrical energy.<\/p>\n<p>The Archimedes screw turbine is made from glass fibre reinforced vinylester composite. Because composite materials are used the turbine has a smooth surface on the inside, which reduces\u00a0loss of energy due to friction to a minimum. Another advantage of using GRP composite is the reduced maintenance need\u00a0compared to conventional steel turbines.<\/p>\n<p>Because the hull is attached to the screw, it rotates along with it. This ensures maximum efficiency because not a single drop of water is lost along the way.[\/vc_column_text][vc_single_image image=&#8221;71422&#8243; img_size=&#8221;full&#8221; css_animation=&#8221;appear&#8221;][\/vc_column][\/vc_row][vc_row type=&#8221;container&#8221; padding_top=&#8221;&#8221; padding_bottom=&#8221;&#8221; css=&#8221;.vc_custom_1449062969962{margin-bottom: 50px !important;}&#8221;][vc_column][vc_tta_tabs style=&#8221;flat&#8221; active_section=&#8221;1&#8243;][vc_tta_section title=&#8221;Product attributes&#8221; tab_id=&#8221;1444300654474-2bfb86dc-fd3a&#8221;][vc_column_text css=&#8221;&#8221;]<\/p>\n<ul>\n<li>100% fish safe<\/li>\n<li>efficiency of 80% feasible at variable flow rates<\/li>\n<li>long lifespan, even in salt water<\/li>\n<li>low maintenance<\/li>\n<li>impervious for debris and obstructions<\/li>\n<li>optional adjustable height for fluctuating water levels<\/li>\n<li>can be used as highly efficient fish friendly pump<\/li>\n<\/ul>\n<p>[\/vc_column_text][\/vc_tta_section][vc_tta_section title=&#8221;Technical specifications&#8221; tab_id=&#8221;1444300654691-e081e086-5ad3&#8243;][vc_column_text]<\/p>\n<ul>\n<li>triple blade screw of GRP composite material<\/li>\n<li>diameters in range from 0.6 to 5.0 meters<\/li>\n<li>maintenance free bottom bearing absorbs axial and radial forces<\/li>\n<li>high efficient gearbox and generator<\/li>\n<\/ul>\n<p>[\/vc_column_text][\/vc_tta_section][\/vc_tta_tabs][\/vc_column][\/vc_row][vc_row type=&#8221;container&#8221; padding_top=&#8221;&#8221; padding_bottom=&#8221;&#8221; css=&#8221;.vc_custom_1444504142602{margin-bottom: 0px !important;}&#8221;][vc_column][vc_separator color=&#8221;#e2e2e2&#8243; type=&#8221;normal&#8221; thickness=&#8221;1&#8243; up=&#8221;&#8221; down=&#8221;&#8221; el_class=&#8221;dotted&#8221;][vc_column_text]<\/p>\n<h2>Impressions<\/h2>\n<p>The photos below show parts of the production process of an Archimedes screw.[\/vc_column_text][vc_images_carousel images=&#8221;71474,71476&#8243; img_size=&#8221;full&#8221; onclick=&#8221;link_no&#8221; autoplay=&#8221;yes&#8221; wrap=&#8221;yes&#8221; el_class=&#8221;borderpx&#8221;][\/vc_column][\/vc_row][vc_row type=&#8221;container&#8221; padding_top=&#8221;&#8221; padding_bottom=&#8221;&#8221; css=&#8221;.vc_custom_1444504142602{margin-bottom: 0px !important;}&#8221;][vc_column][vc_separator color=&#8221;#e2e2e2&#8243; type=&#8221;normal&#8221; thickness=&#8221;1&#8243; up=&#8221;&#8221; down=&#8221;&#8221; el_class=&#8221;dotted&#8221;][vc_column_text]<\/p>\n<h2>Get a quotation<\/h2>\n<p>If you are interested in an Archimedes screw turbine that is durable, high-efficient and fish friendly?
