Two questions about liquid ring vacuum pump
1. if the liquid ring pump is not equipped with by-pass control, when gas stream is much lower than the pump working curve, will the pump be damaged?
For example, flowserver LPHX45008, 1740 rpm, at min. suction pressure 33 mbara, dry gas flow is 50m3/h. Gas from process is only around 5 m3/h. What will happen with the pump?
2. Condensable flows into the pump. Some articles say that liquid ring pump is designed for get rid of non-condensable, there must be a condenser upstream the pump to remove the condensable as much as possible. Some says, the condensable condensing in the seal liquid increases the pump capacity.
Which opinion is correct? One of the our systems has no condenser, can I install a liquid ring pump?
Thanks in advance.
