Cooling Tower Suction Piping Guidelines

Cooling Tower Suction Piping Guidelines

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…

How to Determine Control Head for a Variable Speed Pumping System

How to Determine Control Head for a Variable Speed Pumping System

To 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 ...
