I’d like to ask what “closed” means

In the pump data sheet of the process package, the material of the impeller is listed as 304L SS (closed). Could you please explain what \"closed\" means? Thank you

It’s not exactly the same; some pumps have an IMPELLER made of Duplex 2205 SS, while other pumps have an IMPELLER made of 316L SS. None of them come with a closed design – if they had closed impellers, then all of them would have that feature
