Question: What mesh size is suitable for the filter element before the chilled water pump?
It is recommended to use a filter with a mesh size of 40-60.
I’m not entirely sure what fluid is used in the chilled water pump you’re referring to, but oil pumps typically use a 50-mesh filter. In my opinion, the filtration accuracy is also related to the structure of the pump; if it has an open impeller, the filtration accuracy need not be considered.
The medium is demineralized water. It operates in a closed cycle. The pump is a single-stage centrifugal pump with a closed impeller
40 mesh is sufficient: handshake.
A higher mesh count is also possible, “closed-loop”.
Centrifugal pump filters don’t have a specific mesh count; typically, a plate with holes of 4–5 mm in diameter, distributed across a surface with 6–10 mm spacing, is used and installed inside the filter chamber (it should be easy to remove). Using 50-mesh will get clogged very quickly. Just a suggestion, for reference!
