Dear experts, I have a question: What type of pump is the stepped-shaped pump head shown in the PID diagram? It’s the area marked with a red circle in the image below
There is a pulse damper at the outlet; it should be a positive displacement pump. It’s not clear what specific type of positive displacement pump it is. Is there no diagram on the home page?
With an outlet pulse damper, it must be a reciprocating pump; the specific type will depend on the instructions. However, this painting style is quite rare. Let’s release the content of Note 2 for everyone to take a look.
There is a damper at the outlet; it should be a positive displacement pump, or it could also be a metering pump
Positive displacement pumps such as metering pumps or plunger pumps
Thank you all for your expert opinions. It seems that our company’s equipment engineers consider such pumps to be metering pumps; perhaps a metering pump is indeed one type of pump represented by this symbol!
