What Is a Desalination Brine Pump?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">A <strong>desalination brine pump<\/strong> is a specialized fluid handling device designed to transport high-salinity concentrated brine \u2014 the byproduct of reverse osmosis (RO) and thermal desalination processes. Unlike standard industrial pumps, a desalination brine pump must withstand:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>TDS concentrations<\/strong> ranging from 50,000 ppm to over 200,000 ppm, depending on feedwater salinity and system recovery rate (typical seawater RO at 50% recovery produces brine at ~70,000 ppm; ZLD systems can exceed 200,000 ppm).<\/li>\n\n\n\n<li><strong>Chloride levels<\/strong> that cause rapid pitting corrosion in standard stainless steels.<\/li>\n\n\n\n<li><strong>Continuous duty cycles<\/strong> common in desalination plants (8,000+ hours\/year).<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">These pumps are deployed at multiple process points: seawater intake, RO feed boosting, brine discharge, and zero-liquid-discharge (ZLD) circulation.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">2. Corrosion Challenges in High-Salinity Brine Service<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">2.1 Chloride-Induced Pitting and PRE Value<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Chloride ions attack the passive oxide film on stainless steel, creating localized pits that can penetrate the wall within months. The <strong>Pitting Resistance Equivalent (PRE)<\/strong> value is the standard metric for ranking a material&#8217;s resistance to chloride pitting:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>PRE = %Cr + 3.3 \u00d7 %Mo + 16 \u00d7 %N<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>304: PRE 18\u201320 \u2192 limited to ~200 ppm chloride at 60\u00b0C<\/li>\n\n\n\n<li>316L: PRE 24\u201326 \u2192 limited to &lt;1,000 ppm chloride<\/li>\n\n\n\n<li>2507 super duplex: PRE 42\u201345 \u2192 withstands &gt;15,000 ppm chloride<\/li>\n<\/ul>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\n<p class=\"wp-block-paragraph\"><strong>Reference:<\/strong> PRE values are determined per ASTM G48 standard test methods for pitting and crevice corrosion resistance of stainless steels.<\/p>\n<\/blockquote>\n\n\n\n<h3 class=\"wp-block-heading\">2.2 Stress Corrosion Cracking (SCC)<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The combination of tensile stress, temperature, and chloride ions causes rapid crack propagation. Austenitic grades (304, 316L) are most vulnerable; duplex grades (2205, 2507) offer significantly better SCC resistance due to their ferritic-austenitic microstructure.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">2.3 Crevice Corrosion<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Gasketed joints, seal faces, and bolted connections create oxygen-depleted zones where localized corrosion accelerates. This is the most common failure location in brine pumps and is addressed by selecting higher PRE materials and optimizing seal design.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">3.

Frequently Asked Questions<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Q1: What is the recommended material for a desalination brine pump?<\/strong><br>For concentrated brine (TDS &gt;65,000 ppm), <strong>2507 baja tahan karat super dupleks<\/strong> is the recommended material. For moderate seawater conditions, <strong>2205 duplex<\/strong> provides an optimal balance of cost and corrosion resistance. For applications involving fluorides or reducing acids, use 2507 or high-chromium alloys instead of titanium.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Q2: What is the maximum chloride concentration for 316L in brine service?<\/strong><br>316L is generally limited to environments with less than <strong>1,000 ppm chloride at ambient temperature<\/strong>. Above this threshold, pitting corrosion accelerates significantly. Most seawater brine applications (15,000\u201320,000 ppm Cl\u207b) require at least 2205 duplex.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Q3: How to choose between single-stage and multistage pump for brine?<\/strong><br>Use the <strong>head requirement<\/strong> as the primary decision criterion:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Head \u2264130 m:<\/strong> CYH single-stage is typically more economical<\/li>\n\n\n\n<li><strong>Head &gt;130 m or up to 816 m:<\/strong> DF multistage is required<\/li>\n\n\n\n<li>Also consider temperature: CYH supports up to 165\u00b0C, DF is limited to 80\u00b0C<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Q4: What seal type is recommended for high-salinity brine?<\/strong><br><strong>Dual mechanical seal with API Plan 32 clean water flush<\/strong> is recommended for crystallizing brine. For clean brine without crystallization risk, a single SiC\/SiC mechanical seal with API Plan 11 recirculation is sufficient.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Q5: What is the maximum temperature for brine pump operation?<\/strong><br>Untuk <strong>CYH series<\/strong>: -20\u00b0C to 165\u00b0C depending on material configuration. For <strong>DF series<\/strong>: \u226480\u00b0C. For titanium pumps, the practical limit is approximately 120\u00b0C for chloride immunity.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Q6: How does PRE value affect material selection?<\/strong><br>PRE value is the primary indicator of chloride pitting resistance. The formula is <strong>PRE = %Cr + 3.3\u00d7%Mo + 16\u00d7%N<\/strong>. A higher PRE value indicates better resistance to chloride-induced pitting. For brine service, PRE \u2265 34 (2205 or 904L) is the minimum recommended threshold.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Q7: Can titanium be used for all desalination brine pumps?<\/strong><br><strong>Tidak.<\/strong> Titanium offers excellent chloride resistance (near-immune up to 120\u00b0C) but has critical limitations: it is <strong>not suitable for fluorides<\/strong> (e.g., hydrofluoric acid), <strong>not recommended for reducing acids<\/strong> (e.g., dilute sulfuric acid), and has <strong>low wear resistance<\/strong> (HB 180\u2013210, lowest among the six grades). Titanium should only be used for &#8220;clean but corrosive&#8221; brine.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Q8: What causes pump failure in desalination plants?<\/strong><br>The most common failure modes in order of frequency:<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>Korosi<\/strong> (pitting, SCC, crevice corrosion) \u2014 45% of failures<\/li>\n\n\n\n<li><strong>Kegagalan segel mekanis<\/strong> \u2014 30% of failures<\/li>\n\n\n\n<li><strong>Bearing failure<\/strong> due to axial thrust imbalance \u2014 15% of failures<\/li>\n\n\n\n<li><strong>Cavitation damage<\/strong> \u2014 10% of failures<\/li>\n<\/ol>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">10. Environmental Compliance and Regulatory Considerations<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Brine discharge from desalination plants is subject to environmental regulations that may affect pump selection:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>U.S. EPA 316(b):<\/strong> Requires cooling water intake structures to minimize environmental impact<\/li>\n\n\n\n<li><strong>EU Water Framework Directive:<\/strong> Regulates brine discharge into coastal waters<\/li>\n\n\n\n<li><strong>Local regulations in the Middle East and Australia:<\/strong> Increasingly stringent brine concentration limits for discharge<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">ZLD (Zero Liquid Discharge) systems are becoming mandatory in many regions, requiring pumps capable of handling brine concentrations exceeding 200,000 ppm TDS \u2014 a duty that demands <strong>2507 super duplex or titanium materials<\/strong> dan <strong>DF series multistage architecture<\/strong>.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">11.
