Variable Speed Pressure Boosters and Hydropneumatic Tanks

The question is being asked more frequently: do commercial pressure boosting packages require a hydropnumatic tank? The answer is no. Without a tank, a pressure boosting package will still operate as intended. In response to feedback from the system, the package will provide varying discharge pressures and flows relative to the changing requirements of the application. So, if not an intrinsic requirement for the booster, the question then becomes: should a hydropneumatic tank be utilized in pressure boosting applications? Bell and Gossett strongly recommends the latter.
