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.

Calif. Utility Earns Fast Payback On Pump Retrofit

The Cupertino Sanitary District (CSD) recently underwent significant equipment upgrades at its lift stations. The district's submersible pumps now operate with a new type of impeller designed to virtually eliminate blockages. During the year following the pump retrofit program, the utility saved several thousand dollars by preventing all but one blockage. Additional energy savings are being realized due to the suspended high operating efficiency offered by the new pumps.

What Is L3/D4 and Why Is It Good for the Seals If It Is Low?

What is L3/D4 (L cubed over D to the fourth)? It is a measure of pump rotor stiffness, its ability to resist radial load and to minimize deflection. It comes from the basic cantilevered beam deflection formula, which you can find in any book on mechanics: y = F x L3 / (3 x E x I), where F is radial load, L is cantilevered length, E modulus is the elasticity of the material and I is moment of inertia.
