These small but efficient pumps are based on the use of a fixed geometry and either rotating axial pistons or crank-driven pistons to pressurize water in the chambers.<\/p>\n<p>As the size and pumping capacity of these chambers increase, these smaller PD pumps face mechanical challenges. As a result, previous larger PD pumps have either featured a larger crankshaft or high crankshaft speeds to overcome these, but the larger size and operating speeds have led to significant vibration and maintenance issues.<\/p>\n<p>IPER solves these problems, says GE, by eliminating the crankshaft and replacing it with a hydraulic drive system for both functions. The drive powers three double-acting pistons in the water displacement unit and does this at very slow cycle speeds compared with traditional PD pumps.<\/p>\n<p>These innovations allow larger seawater reverse-osmosis systems using less efficient centrifugal pumps to incorporate IPER PD pumps in the future. Since PD pumps are typically used on systems with a capacity of less than 1,000 m\u00b3\/d, this offers opportunities for any plant of 1,000 m\u00b3\/d or larger to achieve substantial energy savings.<\/p>\n<p>&#8220;IPER is designed to offer customers reliable uptime for their packaged desalination water treatment plants while reducing their energy costs in a significant and quantifiable way,&#8221; said Heiner Markhoff, president and CEO &#8211; water and process technologies for GE Power &amp; Water. &#8220;IPER represents a major economic and technical break-through that is poised to help desalination operators play an even greater role in addressing the world&#8217;s mounting water scarcity problems.&#8221;<\/p>\n<p>Source: <a href=\"http:\/\/www.desalination.biz\" target=\"_blank\">Desalination &amp; Water Reuse<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Bahamas Water &#038; Sewerage Corporation has installed a pilot IPER system at a desalination facility in Tarpum Bay to demonstrate the efficiency and reliability of the technology.<\/p>\n","protected":false},"author":14,"featured_media":0,"comment_status":"open","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"rop_custom_images_group":[],"rop_custom_messages_group":[],"rop_publish_now":"initial","rop_publish_now_accounts":{"facebook_10223285771444175_51037792744":""},"rop_publish_now_history":[],"rop_publish_now_status":"pending","footnotes":""},"categories":[18],"tags":[211],"class_list":["post-23363","post","type-post","status-publish","format-standard","hentry","category-lifestyle","tag-water-sewerage"],"_links":{"self":[{"href":"https:\/\/www.bahamasb2b.com\/news\/wp-json\/wp\/v2\/posts\/23363","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.bahamasb2b.com\/news\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.bahamasb2b.com\/news\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.bahamasb2b.com\/news\/wp-json\/wp\/v2\/users\/14"}],"replies":[{"embeddable":true,"href":"https:\/\/www.bahamasb2b.com\/news\/wp-json\/wp\/v2\/comments?post=23363"}],"version-history":[{"count":0,"href":"https:\/\/www.bahamasb2b.com\/news\/wp-json\/wp\/v2\/posts\/23363\/revisions"}],"wp:attachment":[{"href":"https:\/\/www.bahamasb2b.com\/news\/wp-json\/wp\/v2\/media?parent=23363"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.bahamasb2b.com\/news\/wp-json\/wp\/v2\/categories?post=23363"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.bahamasb2b.com\/news\/wp-json\/wp\/v2\/tags?post=23363"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
