Welcome to the Hoover Dispatch, our e-newsletter designed to keep you up-to-date on products, services, and cutting-edge technology that affects irrigation and other types of pump systems. Articles will feature topics of general interest to those maintaining irrigation and other types of pump systems.

We value your feedback, so feel free to write, call, or e-mail us your comments.

With the help of our new mascot, H20, this part of our newsletter will be dedicated to answering some of your questions regarding the operation and maintenance of pumping systems. Simply e-mail your questions to us and we'll forward them on to H2O for an answer.

Our first question deals with:

Power Quality Problems and their Effect on Pump Systems

What is a power quality problem?

Power quality problems can manifest themselves in two common ways: 1) voltage transients, and 2) current unbalance. A voltage transient is a sudden change in voltage. Signs may include the sudden dimming or turning off of lights, digital clocks blinking, smoke alarms going off without the presence of smoke, etc.

How does it affect a pump system?

Metal Oxice Varistors (M.O.V.'s) are standard equipment on all Hoover pump systems and are installed to limit the damage caused by voltage transients. They help protect components of the system by absorbing energy and redirecting damaging current. In performing this protective function, MOVs become degraded, requiring replacement.

If you suspect a power quality problem, how will Hoover help you?

Hoover technicians will check your system and replace any necessary componants. In addition, they will check the current and voltage balance to ensure proper power supply. Continued operation with an power supply may result in damaged equipment.
