The rotor is made of AISI 304 stainless steel and coated with a hard chrome surface.<\/p>\n<p>During operation, the rotor moves on the rubber surface and it\u2019s lubricated by the pumped water. The flow rate is directly proportional to pump speed while the pres-sure supplied is kept almost constant.<\/p>\n<p>In this way, unlike a centrifugal pump, the helical rotor pump provides high head even at low rpm, ensuring water on surface even with very low available power or low irradiation. In addition, the helical rotor pumps feature higher hydraulic efficiency than centrifugal pumps of same flow.<\/p>\n<p>This saves in the number of PV panels necessary for the application.<\/p>\n<\/div><\/section><\/div>\n\n<style type=\"text\/css\" data-created_by=\"avia_inline_auto\" id=\"style-css-av-4m5ps3-1a560bafd373c2e06591dc5375316e2b\">\n.flex_column.av-4m5ps3-1a560bafd373c2e06591dc5375316e2b{\nborder-radius:0px 0px 0px 0px;\npadding:0px 0px 0px 25px;\n}\n<\/style>\n<div  class='flex_column av-4m5ps3-1a560bafd373c2e06591dc5375316e2b av_one_half  avia-builder-el-2  el_after_av_one_half  avia-builder-el-last  no_margin flex_column_div av-animated-generic bottom-to-top  '     ><style type=\"text\/css\" data-created_by=\"avia_inline_auto\" id=\"style-css-av-25g4n7-1472a5907a65a616153a1a6c18e37256\">\n.avia-image-container.av-25g4n7-1472a5907a65a616153a1a6c18e37256 img.avia_image{\nbox-shadow:none;\n}\n.avia-image-container.av-25g4n7-1472a5907a65a616153a1a6c18e37256 .av-image-caption-overlay-center{\ncolor:#ffffff;\n}\n<\/style>\n<div  class='avia-image-container av-25g4n7-1472a5907a65a616153a1a6c18e37256 av-styling- avia-align-center  avia-builder-el-3  avia-builder-el-no-sibling '   itemprop=\"image\" itemscope=\"itemscope\" itemtype=\"https:\/\/schema.org\/ImageObject\" ><div class=\"avia-image-container-inner\"><div class=\"avia-image-overlay-wrap\"><img decoding=\"async\" fetchpriority=\"high\" class='wp-image-11358 avia-img-lazy-loading-not-11358 avia_image ' src=\"https:\/\/nastec.eu\/en\/wp-content\/uploads\/2024\/09\/Helicoidal-rotor-pump-NERA-it.jpg\" alt='' title='Helicoidal-rotor-pump-NERA-it'  height=\"800\" width=\"157\"  itemprop=\"thumbnailUrl\" srcset=\"https:\/\/nastec.eu\/en\/wp-content\/uploads\/2024\/09\/Helicoidal-rotor-pump-NERA-it.jpg 157w, https:\/\/nastec.eu\/en\/wp-content\/uploads\/2024\/09\/Helicoidal-rotor-pump-NERA-it-59x300.jpg 59w\" sizes=\"(max-width: 157px) 100vw, 157px\" \/><\/div><\/div><\/div><\/div>\n","protected":false},"excerpt":{"rendered":"","protected":false},"author":2,"featured_media":0,"parent":362,"menu_order":0,"comment_status":"closed","ping_status":"closed","template":"","meta":{"footnotes":""},"categories":[40],"tags":[39,11],"class_list":["post-2947","page","type-page","status-publish","hentry","category-focus-nera","tag-focus-nera","tag-nera"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v28.3 -
