Seawater service has a true corrosion effect and the alloys that it supports operate fundamentally differently from the steels proposed for fresh water use. This is why the three breakdown modes below are common to so many industrial estate repairs and are again all driven by exactly one root problem.<\/p>\n      <\/div>\n    <\/div>\n  <\/div>\n\n  <div class=\"qiz-content-band\">\n    <div class=\"qiz-container\">\n      \n      <div class=\"qiz-grid-layout\">\n        <div class=\"qiz-flat-card\">\n          <div class=\"qiz-icon-box\">\n            <svg class=\"qiz-icon-svg\" viewBox=\"0 0 24 24\">\n              <path d=\"M13 2L3 14h9l-1 8 10-12h-9l1-8z\" \/>\n            <\/svg>\n          <\/div>\n          <h3 class=\"qiz-card-title\">Corrosion Failure<\/h3>\n          <p class=\"qiz-card-desc\">Chloride pitting, galvanic attack between different flange metals, microbiologically-influenced corrosion in dead-legs are always lurking in the background and quietly trimming MTBF.

Model names encode flow-head-impeller-diameter at the BEP: a QIZ100-65-200 delivers roughly 100 m\u00b3\/h (440 GPM) through a 65 mm discharge with a 200 mm impeller.

Our foundry supports alloy upgrades, flow and head point customization, special seal arrangements, non-standard shaft lengths, coating systems, and ATEX or explosion-proof motor options. New casting tooling has a longer lead time (~6 10 weeks typical) but delivers fully custom hydraulic profiles. For some minor modifications (e.g.Non-standard connections, different position for motor mountings, more tappings on instrumentation etc.) on conventional QIZ frames, we typically add 1 - 2 weeks to the normal delivery times.\"\n      }\n    }\n  ]\n}\n<\/script>\n\n<script>\n(function initFaqPerformance() {\n    function setupFaq() {\n        const faqContainer = document.querySelector('#b2b-pro-faq-v3 .faq-grid');\n        if (!faqContainer) return;\n\n        \/\/ \u9884\u5148\u7f13\u5b58\u6240\u6709\u9879\uff0c\u907f\u514d\u6bcf\u6b21\u70b9\u51fb\u65f6\u67e5\u8be2 DOM\n        const allItems = Array.from(faqContainer.querySelectorAll('.faq-item'));\n\n        \/\/ \u4f7f\u7528\u4e8b\u4ef6\u59d4\u6258\uff0c\u53ea\u9700\u5728\u7236\u5bb9\u5668\u7ed1\u5b9a\u4e00\u6b21\u76d1\u542c\u5668\n        faqContainer.addEventListener('click', function(e) {\n            const trigger = e.target.closest('.faq-trigger');\n            if (!trigger) return;\n\n            const currentItem = trigger.parentElement;\n            const content = currentItem.querySelector('.faq-content');\n            const isActive = currentItem.classList.contains('active');\n\n            \/\/ \u9501\u5e27\u6267\u884c\uff0c\u786e\u4fdd\u52a8\u753b\u6d41\u7545\u4e14\u4e0d\u4f1a\u89e6\u53d1\u989d\u5916\u7684\u91cd\u6392\n            requestAnimationFrame(() => {\n                if (!isActive) {\n                    \/\/ \u5173\u95ed\u5176\u4ed6\u5df2\u6253\u5f00\u7684\u9879\n                    allItems.forEach(item => {\n                        if (item !== currentItem && item.classList.contains('active')) {\n                            item.classList.remove('active');\n                            item.querySelector('.faq-content').style.maxHeight = null;\n                        }\n                    });\n                    \n                    \/\/ \u6253\u5f00\u5f53\u524d\u9879\n                    currentItem.classList.add('active');\n                    content.style.maxHeight = content.scrollHeight + \"px\";\n                } else {\n                    \/\/ \u5173\u95ed\u5f53\u524d\u9879\n                    currentItem.classList.remove('active');\n                    content.style.maxHeight = null;\n                }\n            });\n        });\n    }\n\n    \/\/ \u517c\u5bb9 FlyingPress \u7b49\u5ef6\u8fdf\u52a0\u8f7d\u63d2\u4ef6\n    if (document.readyState === 'loading') {\n        document.addEventListener('DOMContentLoaded', setupFaq);\n    } else {\n        setupFaq();\n    }\n})();\n<\/script>\n<\/div><\/div><\/div>\n<\/div><\/div>\n","protected":false},"excerpt":{"rendered":"<p>Sea Water Pump Sea Water Pump \u2014 QIZ Horizontal Centrifugal by BBP (ISO\/ABS \u00b7 6 Alloys \u00b7 2-Week Lead Time) Industrial-grade centrifugal pumps engineered for chloride concentrations up to 35,000 ppm, heads to 125 m, and flows from 3 to 1,000 m\u00b3\/h.
