The external structure consists of a cylindrical body in high-resistance 1.4031 EN AISI 304 stainless steel, integrated with a pump body also in 1.4031 EN AISI 304 stainless steel, which guarantees structural robustness and long operating life. The GFN2V Noril impeller has been specially designed to maximize hydraulic efficiency and ensure high and constant performance. The shaft, made of Cr 1.4301 EN stainless steel, combines excellent mechanical properties with strong resistance to corrosion, thus increasing the overall longevity of the pump. The delivery body is also made of 1.4031 EN AISI 304 steel and houses a guide bearing in acetal resin, while filters and screws are made of resistant stainless steel, guaranteeing durability and reliability over time. The 4SDPM series is available in three powers \u2013 1HP, 1.5HP and 2HP \u2013 offering versatility and consistent performance in a wide range of industrial and civil applications.<\/p>\n<p data-start=\"851\" data-end=\"989\"><b>Execution;<\/b><\/p>\n<div class=\"vc_col-sm-6 wpb_column column_container vc_column_container col child_column no-extra-padding inherit_tablet inherit_phone\" data-padding-pos=\"all\" data-has-bg-color=\"false\" data-bg-color=\"\" data-bg-opacity=\"1\" data-animation=\"\" data-delay=\"0\">\n<div class=\"vc_column-inner\">\n<div class=\"wpb_wrapper\">\n<div class=\"wpb_text_column wpb_content_element\">\n<div class=\"wpb_wrapper\">\n<ul>\n<li>Submersible pumps for 4\" (DN 100 mm), 6\" (DN 150 mm) deep wells, with external jacket in AISI 304 stainless steel.<\/li>\n<li>Impellers.<\/li>\n<li>4SDP floating radials.<\/li>\n<li>6SDP radials.<\/li>\n<li>ISO 228 threaded mouth.<\/li>\n<li>Check valve incorporated in the delivery body.<\/li>\n<\/ul>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<p data-start=\"550\" data-end=\"642\"><strong data-start=\"114\" data-end=\"130\">Applications;<\/strong><\/p>\n<ul>\n<li>For water supply.<\/li>\n<li>For civil and industrial applications.<\/li>\n<li>For fire prevention systems.<\/li>\n<li>For irrigation.<\/li>\n<\/ul>\n<p><strong>Limits of use;<\/strong><\/p>\n<ul>\n<li>Pump.<\/li>\n<li>Water temperature.<\/li>\n<li>up to 35 \u00b0C with 4\u2033 motor.<\/li>\n<li>up to 30 \u00b0C with 6\u2033 motor.<\/li>\n<li>Maximum amount of sand in the water.<\/li>\n<li>150 g\/m3 for 4SDP and 300 g\/m3 for 6SDP.<\/li>\n<li>300 g\/m3 for pumps with high sand content.<\/li>\n<li>Continuous service.<\/li>\n<\/ul>","protected":false},"excerpt":{"rendered":"<article class=\"text-token-text-primary w-full focus:outline-none scroll-mt-[calc(var(--header-height)+min(200px,max(70px,20svh)))]\" dir=\"auto\" data-turn-id=\"request-68c3de34-f68c-8333-980a-a7f9a834a188-43\" data-testid=\"conversation-turn-224\" data-scroll-anchor=\"true\" data-turn=\"assistant\">\n<div class=\"text-base my-auto mx-auto pb-10 [--thread-content-margin:--spacing(4)] thread-sm:[--thread-content-margin:--spacing(6)] thread-lg:[--thread-content-margin:--spacing(16)] px-(--thread-content-margin)\">\n<div class=\"[--thread-content-max-width:40rem] thread-sm:[--thread-content-max-width:40rem] thread-lg:[--thread-content-max-width:48rem] mx-auto max-w-(--thread-content-max-width) flex-1 group\/turn-messages focus-visible:outline-hidden relative flex w-full min-w-0 flex-col agent-turn\">\n<div class=\"flex max-w-full flex-col grow\">\n<div class=\"min-h-8 text-message relative flex w-full flex-col items-end gap-2 text-start break-words whitespace-normal [.text-message+&amp;]:mt-5\" dir=\"auto\" data-message-author-role=\"assistant\" data-message-id=\"3aa7a383-b894-4697-b4eb-782574409b2f\" data-message-model-slug=\"gpt-5-mini\">\n<div class=\"flex w-full flex-col gap-1 empty:hidden first:pt-[3px]\">\n<div class=\"markdown prose dark:prose-invert w-full break-words light markdown-new-styling\">\n<p data-start=\"0\" data-end=\"477\" data-is-last-node=\"\" data-is-only-node=\"\">La 4SDPM di Calpeda \u00e8 una pompa sommersa da 4&#8243; in acciaio inox AISI 304, progettata per garantire robustezza, lunga durata e prestazioni idrauliche elevate grazie alla girante in Noril.
