What type of valve is used on screw pumps?
Thread Content
I have a question: does anyone know what model of check valve this is in the photography community? ? ? Or what other type of valve? ? ?

This is a pump used in the pharmaceutical industry; it is indeed very small and its price is quite attractive.

It can’t be a silencer. The area I’ve circled shows the left view; the small thing on the left is the silencer, while it’s on the right: lol
According to this view, it’s either the one on the right or the oil cup on the left, right?
It’s the one on the left. That one in the picture is an air filter; it can also be called a breathing mask. It’s not the oil cup; the oil cup is on top of the front and rear gearboxes. This position is where the pump chamber is near the exhaust end. Air filters are generally connected to the pump body by threading, just as shown in your diagram. I sent that photo; I don’t know why there’s a stainless steel piece added in the middle. Speaking of check valves, the pressure difference there isn’t very large; I’m not sure what the starting pressure difference is. If it’s not a one-way valve, I can’t think of anything else useful that could be used.
Is there no manufacturer’s manual? Or contact the manufacturer for inquiries!
The documentation indicates it is for cooling and purging
