Pump System Controllers for Leakage Management

The purpose of this paper is to discuss utilization of flow-controlled pump stations as a method to reduce distribution system leakage and, as an additional benefit, reduce power costs associated with the more traditional constant pressure systems. Though conceptual, this article discusses in general terms pump station controllers that are being used to track the varying pressure requirements in distributions systems. By anticipating those requirements based upon flow, modern day pumping systems controllers can provide smooth-flow systems that meet the minimum pressure requirements.

Selecting a Pump for Seawater Reverse Osmosis

Although the pump is a relatively small part of the overall cost of an RO system, expenses resulting from downtime and inefficiency quickly can diminish the productivity of the system and your return on investment. Due to the corrosive atmosphere and high demands on these sea water RO systems, special attention is required in the pump selection process. There are several key factors that will help to ensure optimum pump and system performance.
