...new pump is working fine, it was a pump problem.<br /><br />can any one tell ,wahat is the pump "maximum working pressure rating" is.<br /><br />if the manufacturer says 210 bar .<br />it means 0 pressure on suction port and 210 bar on outlet.<br /><br />can i give 50 bar on suction port and make the pump work at 260 bar without redusing the pump lifetime.<br /> the pump is not going to explode at 260 i am sure.hydohttps://www.blogger.com/profile/17817040001983212190noreply@blogger.comtag:blogger.com,1999:blog-4315911668447344547.post-69562682393746158672010-01-08T00:21:02.785-08:002010-01-08T00:21:02.785-08:00the third port on thr relief is blocked .fluid is ...the third port on thr relief is blocked .fluid is going no where , the only way out is the relief valve.<br /><br />any how i am installing a new pump tommarow.hydohttps://www.blogger.com/profile/17817040001983212190noreply@blogger.comtag:blogger.com,1999:blog-4315911668447344547.post-9862668650164872072010-01-07T04:23:37.703-08:002010-01-07T04:23:37.703-08:00"then i truned it more after showing 175 bar ..."then i truned it more after showing 175 bar the guage reading goes down ,even if i set the relief at full pressure 315 bar."<br /><br />1.

A direct operated rel...Thank you for the question.<br /><br />A direct operated relief is typically faster acting than a pilot relief - usually less than 100 msec. If you are seeing this on a gage, maybe your relief is dirty and therefore lagging. Maybe your monoblock is shifting slowly and temporarily blocking fluid. If you are clearly seeing this spike on a gage I would start with a problematic relief.JDKhttps://www.blogger.com/profile/16796281957964741569noreply@blogger.com
