The diameter of the pump suction pipe should not be too large
Thread Content
It’s common to see statements in various sources saying that the diameter of the pump suction pipeline should not be too large. I’ve never understood why this is the case – a larger diameter results in less inlet friction, which is beneficial for the pump’s suction process, so why isn’t it advisable to use a larger diameter? Is it because the pipe diameter is large and the sealing is poor? ? ?
If the diameter of the inlet pipe is increased excessively, the flow velocity will decrease, and deposition will occur when the flow velocity is very low
Thank you for the reply. What is deposition, and what harm does it cause to the pump’s suction?
Being too large is also a waste; larger sizes increase the costs of procurement and installation
Deposition mainly refers to the continuous settling of solid particles suspended in a liquid
