Booster Pump - an overview | ScienceDirect Topics

Seal systems are an important consideration on the reflux pumps when treating H 2 S gases, as seal failure will result in H 2 S emissions. Selection of the circulation pump depends on the contactor operating pressure and the amine circulation rate. Positive displacement pumps should be considered for 250 gpm and below and for high discharge

Pump Head vs Discharge Pressure (Easy explanation and

Aug 10, 2017 · Head is useful because it evaluates a pump's capacity to do a job. If you have to pump a liquid up to 10m and your pump doesn't have at least 10m of head, then there is no chance it will work. Your pump will need at least 10m plus the friction loss to get the required flow at the discharge point.

Oct 15, 2014 · In a typical eight foot high basement, the head height is 10 feet, accounting for the depth of the sump basin. If the head height is smaller, the pump will move a little more water per minute; if it is larger, the capacity will diminish. More importantly, the capacity rating of the sump pump is also based on using the right-sized discharge pipe. Most sump pumps have a built-in fitting for a certain sized discharge …
