КАНАЛИЗАЦИОННЫЙ НАСОС С ТЕХНОЛОГИЕЙ N
Насосы Flygt серии Flygt N успешно справляются с самыми сложными задачами по перекачиванию сточных вод, в том числе при перекачивании волокнистых включений. Конструкция насоса обеспечивает стабильно высокие показатели эффективности. Благодаря запатентованной N-технологии с инновационным самоочищающимся рабочим колесом, насосы серии Flygt N обладают наивысшей эффективностью в своем классе, что позволяет существенно снизить затраты на электроэнергию и незапланированное техобслуживание. Для пользователя гарантирует спокойствие и большую экономию в течение длительного времени.
Конструкция насоса спроектирована таким образом, что большинство твердых включений, попадающих в насос, будут проходить сквозь рабочее колесо между его лопастями. Любое засорение, попадающее на переднюю кромку лопасти проходит вдоль загнутой назад кромки к периметру впуска и не засоряет рабочее колесо.
Благодаря механической самоочищающейся конструкции насос может перекачивать жидкости с содержанием шлама до 8%.
ГИБКАЯ И МОДУЛЬНАЯ КОНСТРУКЦИЯ
Самоочищающийся насосы Flygt серии N имеют инновационные характеристики и являются отличным выбором для различных сфер применения. Модульная конструкция гидравлики позволяет адаптировать ее под необходимые задачи.
- Заменяемое износное кольцо в двух материалах: серый чугун или высокохромистый чугун Hard IronTM в зависимости от условий эксплуатации
- Рабочее колесо из высокопрочного серого чугуна для обычный сточных вод
- Рабочее колесо из высокохромистого чугуна Hard IronTM для абразивных и высококоррозийных сред.
- Возможность модификации с режущей вставкой для резки длинных волокон или твердых материалов в канализационных стоках.
- Рабочее колесо из нержавеющей стали для специальных применений, требующих использования дуплексной нержавеющей стали.
- Небольшое смещение вала снижает прогиб вала и увеличивает срок службы уплотнений и подшипников.
- Конструкция двигателя разработана специально для погружной установки. Тепло концентрируется в сердечнике статора для улучшения охлаждающих свойств.
- Картриджные уплотнения Flygt Plug-in Seals™ с системой Active Seal™ исключают риск неправильной установки и небрежной эксплуатации. В зависимости от применения доступны материалы из карбида вольфрама (WCCR) или карбида кремния (SiC).
- Кабель двигателя SUBCAB® разработан специально для погружного применения.
- Гибкий выбор системы охлаждения: замкнутая система охлаждения, охлаждение средой или внешнее охлаждение.
