I know the model of the pump, but I’m not sure what type of pump it is; I’m seeking help
Thread Content
The pump model is 3HY-10/4-TB; it is not known what type of pump it is – a multi-stage pump or a positive displacement pump. Help is requested
The pump models are not consistent; common models are fine, but it’s difficult to determine the type of this one...
It’s probably not a submersible pump; this pump is used for transporting materials, its inlet is connected to a high-level material tank, and the pump is located below the tank
Many of those with the letter Y are submersible pumps or oil pumps
Generally, manufacturers come up with their own model numbers for such products; after all, standard pump models are uniform. It’s better to have pictures of the pump to make an accurate assessment
Unless it’s someone from the manufacturer of this type of pump who can tell at a glance, everyone else has to guess
I agree with the deputy editor’s suggestion; it would be better to include a photo, otherwise everyone’s replies will be speculative, and it will be difficult to determine what’s true or false.
First of all, positive displacement pumps generally cannot hold pressure; when starting the pump, do you open the outlet valve first or the pump itself first? If a pump is started first, then it definitely isn’t a positive-displacement pump. As the name implies, a multi-stage pump features a row of impellers along a long shaft – is your pump elongated in shape? It’s useless to say all this; just show me a picture and I can tell you what kind of pump it is
