Are there any relevant standards or specifications for the notation of pump models? Thank you to all the experts!
There are standards; it depends on which type it is. Q: Diving W: Sewage discharge G: Pipeline Y: Submersible N: Mud Z: Self-priming L: Vertical P: Stainless steel B: Explosion-proof and so on. However, things are quite chaotic nowadays; the same type of pump can have several different models designated for it
Included: Q: Diving, W: Sewage discharge, G: Pipeline, Y: Submersible, N: Mud, Z: Self-priming, L: Vertical, P: Stainless steel, B: Explosion-proof, etc. This is just a description of the pump type; the specific model can be found later.
