The containment shell forms a closed system to separate the pumped liquid from the atmosphere by confined gaskets. The equipment (including auxiliaries) is designed and constructed for a minimum service life of 20 years (excluding normal wear parts) and an uninterrupted operation of at least 3 years.<\/p>\n<h3>Applications<\/h3>\n<p>Magnetic coupled PRM-pumps improve plant and personnel safety and reduce maintenance costs, because 90% of these costs are caused by leaking seals. The PRM-pumps will handle nearly all kinds of liquids in the chemical and petrochemical industry, in refineries and industrial<br \/>\nheating plants. Especially liquids which are toxic, flammable, bad smelling or which react on contact with the atmosphere, that means if no leakage is acceptable. For all these services the containment shell replaces the double acting mecha Add a Sitnical seal, along with its external<br \/>\nflushing system and the related control equipment. The performance range of the PRM-pumps is subdivided such that the best efficiency is guaranteed for all service conditions. The capacity goes up to 900 m3\/h (4000 USgpm), the differential head up to 150 mLC (500<br \/>\nft).<\/p>\n<\/aside>\n<aside class=\"col-sm-1\"><\/aside>\n<aside class=\"col-sm-4\">\n<p class=\"align-center\"><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter wp-image-1955 size-full\" src=\"https:\/\/www.apexequipmentltd.com\/wp-content\/uploads\/2015\/05\/process-pump.jpg\" alt=\"Process Pump Ace. to API 685 series PRM\" width=\"200\" height=\"180\" srcset=\"https:\/\/www.apexequipmentltd.com\/wp-content\/uploads\/2015\/05\/process-pump.jpg 200w, https:\/\/www.apexequipmentltd.com\/wp-content\/uploads\/2015\/05\/process-pump-150x135.jpg 150w\" sizes=\"auto, (max-width: 200px) 100vw, 200px\" \/><\/p>\n<h3>Request More Information<\/h3>\n\n<div class=\"wpcf7 no-js\" id=\"wpcf7-f1547-o1\" lang=\"en-US\" dir=\"ltr\" data-wpcf7-id=\"1547\">\n<div class=\"screen-reader-response\"><p role=\"status\" aria-live=\"polite\" aria-atomic=\"true\"><\/p> <ul><\/ul><\/div>\n<form action=\"\/index.php?rest_route=%2Fwp%2Fv2%2Fproduct%2F17978#wpcf7-f1547-o1\" method=\"post\" class=\"wpcf7-form init\" aria-label=\"Contact form\" novalidate=\"novalidate\" data-status=\"init\">\n<fieldset class=\"hidden-fields-container\"><input type=\"hidden\" name=\"_wpcf7\" value=\"1547\" \/><input type=\"hidden\" name=\"_wpcf7_version\" value=\"6.1.5\" \/><input type=\"hidden\" name=\"_wpcf7_locale\" value=\"en_US\" \/><input type=\"hidden\" name=\"_wpcf7_unit_tag\" value=\"wpcf7-f1547-o1\" \/><input type=\"hidden\" name=\"_wpcf7_container_post\" value=\"0\" \/><input type=\"hidden\" name=\"_wpcf7_posted_data_hash\" value=\"\" \/><input type=\"hidden\" name=\"_wpcf7dtx_version\" value=\"5.0.5\" \/><input type=\"hidden\" name=\"_wpcf7_recaptcha_response\" value=\"\" \/>\n<\/fieldset>\n<div class=\"wpcf7-response-output\" aria-hidden=\"true\"><\/div>\n<div class=\"row\">\n\t<aside class=\"col-sm-3\">\n\t\t<p><label for=\"fname\">Name<span class=\"text-danger\">*<\/span><\/label>\n\t\t<\/p>\n\t<\/aside>\n\t<aside class=\"col-sm-9\">\n\t\t<p><span class=\"wpcf7-form-control-wrap\" data-name=\"fname\"><input size=\"40\" maxlength=\"400\" class=\"wpcf7-form-control wpcf7-text wpcf7-validates-as-required\" id=\"fname\" aria-required=\"true\" aria-invalid=\"false\" value=\"\" type=\"text\" name=\"fname\" \/><\/span>\n\t\t<\/p>\n\t<\/aside>\n<\/div>\n<div class=\"row\">\n\t<aside class=\"col-sm-3\">\n\t\t<p><label for=\"email\">Email <span class=\"text-danger\">*<\/span><\/label>\n\t\t<\/p>\n\t<\/aside>\n\t<aside class=\"col-sm-9\">\n\t\t<p><span class=\"wpcf7-form-control-wrap\" data-name=\"email\"><input size=\"40\" maxlength=\"400\" class=\"wpcf7-form-control wpcf7-email wpcf7-validates-as-required wpcf7-text wpcf7-validates-as-email\" id=\"email\" aria-required=\"true\" aria-invalid=\"false\" value=\"\" type=\"email\" name=\"email\" \/><\/span>\n\t\t<\/p>\n\t<\/aside>\n<\/div>\n<div class=\"row\">\n\t<aside class=\"col-sm-3\">\n\t\t<p><label for=\"email\">Product Name<\/label>\n\t\t<\/p>\n\t<\/aside>\n\t<aside class=\"col-sm-9\">\n\t\t<p><span class=\"wpcf7-form-control-wrap productname\" data-name=\"productname\"><input type=\"text\" name=\"productname\" class=\"wpcf7-form-control wpcf7-text wpcf7dtx wpcf7dtx-text\" aria-invalid=\"false\"><\/span>\n\t\t<\/p>\n\t<\/aside>\n<\/div>\n<div class=\"row\">\n\t<aside class=\"col-sm-3\">\n\t\t<p><label for=\"msg\">Message <span class=\"text-danger\">*<\/span><\/label>\n\t\t<\/p>\n\t<\/aside>\n\t<aside class=\"col-sm-9\">\n\t\t<p><span class=\"wpcf7-form-control-wrap\" data-name=\"msg\"><textarea cols=\"40\" rows=\"3\" maxlength=\"2000\" class=\"wpcf7-form-control wpcf7-textarea wpcf7-validates-as-required\" id=\"msg\" aria-required=\"true\" aria-invalid=\"false\" name=\"msg\"><\/textarea><\/span>\n\t\t<\/p>\n\t<\/aside>\n<\/div>\n<div class=\"row\">\n\t<aside class=\"col-sm-3\">\n\t\t<p><label for=\"captcha\">Security Code<span class=\"text-danger\">*<\/span><\/label>\n\t\t<\/p>\n\t<\/aside>\n\t<aside class=\"col-sm-2\">\n\t\t<p><input type=\"hidden\" name=\"_wpcf7_captcha_challenge_captcha\" value=\"3436088091\" \/><img loading=\"lazy\" decoding=\"async\" class=\"wpcf7-form-control wpcf7-captchac wpcf7-captcha-captcha\" width=\"84\" height=\"28\" alt=\"captcha\" src=\"https:\/\/www.apexequipmentltd.com\/wp-content\/uploads\/wpcf7_captcha\/3436088091.png\" \/>\n\t\t<\/p>\n\t<\/aside>\n\t<div class=\"row\">\n\t\t<aside class=\"col-sm-3 col-xs-6\">\n\t\t\t<p><div class=\"cf7-cf-turnstile\" style=\"margin-top: 0px;
