Seeking information on screw pumps
Thread Content
There is a bolt on the outlet flange of the screw pump in our unit. I would like to ask: could anyone explain what the purpose of this design is and how it works? Thank you!

The bolts on the outlet flange of the screw pump are typically used to secure or connect pipes, ensuring a stable fluid output during pump operation and preventing leaks. A flange is a disc-shaped connection fitting that allows a pump to be firmly connected to the output pipe using bolts, thereby creating a well-sealed fluid passage. This design facilitates installation and maintenance, while ensuring the safe and efficient operation of the system. .
It seems to be used for installing pressure gauges, or for exhaust, or as a flushing interface for machine seals; if not in use, it can be sealed with a plug as a backup
Inlets and outlets are common on pumps; generally, venting is provided at the highest point of the pipeline, and a pressure gauge can also be installed.
You’re talking about the fixing bolts on the flange – one bolt with a nut used for connection – which is not the same as what I’m referring to.
