Taking a look at the impact of variable speed drives on mechanical seals
The use of variable speed drives has become more prevalent in industry in an effort to increase the efficiency of pumping systems. The ability to adjust the rotational speed of a rotodynamic pump has been a major factor in the ability to match a pump’s hydraulic characteristics to those of the system in which it operates.
Whether the mismatch was due to the variation in required pump output or due to incorrect sizing of the pump in the first place, there is no question that the ability to easily vary the pump speed has been a major advance in the overall performance of the pumping system.
