Talk:Screw pump

The supposed advantage in respect to "foaming" is not exactly right. Foaming depends on other mechanisms, not only pump type, and is not a relevant characteristic of the screw type of pump. Article is very incomplete and does not cite any disadvantage or limitation of this type of pump, like their inability to handle abrasive solids, for example.
