When designing cooling tower suction piping, it is absolutely critical that engineers have sufficient NPSH to the condenser water pump and avoid any piping design errors that could cause air to come out of the pumping solution. If either of these becomes a problem…
Read MoreIn our last blog we introduced the new HI Energy Rating System for clean water pumps. The HI Rating System not only helps engineers pick a more efficient pump, it also makes it easy for utilities to develop incentives that rewards owners for using HI Rated equipment. Several US utilities are already onboard…
Read MoreComparing pump efficiency just got a whole lot easier thanks to a new rating system developed by the Hydraulic Institute (HI). For the first time ever, pump specifiers or purchasers can go directly to an online tool where they can compare the numerical efficiency scores of any pump….
Read MoreIf this series on variable speed pump control has taught us anything it’s that there is no one-type-fits-all control solution. Control strategies must be applied based on the system design as well as ...
Read MoreTo control a variable speed pumping system, we must determine the minimum operational head of the system. Some refer to this value as constant head, minimum head, independent head, etc. Throughout this and in other JMP blogs, we refer to it as ...
