Why is this?   First of all, a rotating single-entry impeller wants to move in an axial direction and usually with lots [...]]]></description> <wfw:commentRss>http://ekwestrel.com/should-pump-users-care-about-axial-thrust/should-pump-users-care-about-axial-thrust/feed</wfw:commentRss> <slash:comments>2</slash:comments> </item> <item><title>What is the Purpose of Minimum Flow?</title><link>http://ekwestrel.com/what-is-the-purpose-of-minimum-flow/what-is-the-purpose-of-minimum-flow</link> <comments>http://ekwestrel.com/what-is-the-purpose-of-minimum-flow/what-is-the-purpose-of-minimum-flow#comments</comments> <pubDate>Fri, 17 Feb 2012 23:13:41 +0000</pubDate> <dc:creator>ekwestrel</dc:creator> <category><![CDATA[Pumps]]></category> <category><![CDATA[continuous operation]]></category> <category><![CDATA[engineering consulting]]></category> <category><![CDATA[engineering consulting services]]></category> <category><![CDATA[intermittent minimum flow]]></category> <category><![CDATA[intermittent operation]]></category> <category><![CDATA[MCSF]]></category> <category><![CDATA[MCTF]]></category> <category><![CDATA[minimum continuous flow]]></category> <category><![CDATA[minimum continuous stable flow]]></category> <category><![CDATA[minimum continuous thermal flow]]></category> <category><![CDATA[minimum flow]]></category> <category><![CDATA[pump]]></category> <category><![CDATA[pump engineering consulting]]></category> <category><![CDATA[shutoff]]></category> <category><![CDATA[temperature rise]]></category> <category><![CDATA[thermal minimum flow]]></category><guid
