It is presumed that the younger unit is used to adjust the feed flow rate or to balance the pressures of the materials and the pump. I’m not sure if it’s correct!

The main consideration is controlling the feed rate; a large circulation mode is used at startup, while a small circulation mode is adopted once the system stabilizes, in order to control the feed rate and the feeding speed.
