The 41st Turbomachinery and the 28th International Pump Users Symposia (Sept. 24 – 27) at the George R. Brown Convention Center were well attended and with the relaxed atmosphere, attendees, presenters and exhibitors had great opportunities to network and have great conversations.
Positive displacement (PD) pumps do not function well if the discharge is blocked. Unlike centrifugal pumps, they have little tolerance for flow restriction. A piston pump will try to continue stroking regardless of whether its discharge valve is open or closed.
"Testing Centrifugal Pumps in the Field,” Pumps & Systems, February 2011, featured an Excel spreadsheet designed to simplify the field test procedure.
Part 1 (Pumps & Systems, August 2012) discussed an example in which neglecting corrections for velocity head and gauge elevation did not introduce significant errors in the calculations.
Aug. 28, 2012 – With Hurricane Isaac reaching Category 1 strength today just after noon (CST) in the Gulf of Mexico, the nation prepares for its impact. The pump and oil and gas industries will be affected and have already taken precautions.
