Which seal is best for screw pump Sealing


Recommended Posts

In the case of a triple screw pump, shaft seals are only needed on the driving rotor. The other rotors, including their bearings, are encased inside the pumping chamber and do not protrude out. In the case of a two screw pump or a four screw pump, both rotors generally protrude through the pump case, into a gearcase where the timing gears are housed. For this reason, four shaft seals are needed in a screw pump with two rotors.

Okay...I might be misinterpreting this....but a Mechanical one DEFINITELY rather than relying on  "wishful thinking"...

Ahh...did you mean a 'rotary' or 'static'...?  in which case a rotary! That said, it MUST be selected appropriately (there's loads of variations) and installed both properly and carefully!

Mechanical Seal for sure in term of operation, but you need to do an assessment considering your application, labor skills, and investment...

Good options always come with its cost...
