Talk:Reciprocating pump

what will happen if the delivery valve of reciprocating pump is closed and pump start

Lets just assume that the pump is primed with a non-compressible fluid such as water or oil. I believe there are three possibilities: Depending on the system the outcome may be one or more of these simultaneously.
 * 1) The fluid will leak past seals or clearances in the pump
 * 2) The pump will fail, or the drive powering the pump will slip or fail
 * 3) The pipeline downstream of the pump will fail

For this reason many systems, will incorporate a pressure relef valve so that the system is never entirely closed. --GILDog (talk) 07:28, 17 February 2011 (UTC)
