Introduced in August 2008, the Retroflo RPC_2000 Pump Control System was designed to control pump stations as a whole, rather than just the individual components within them. Through continuous dynamic monitoring of the characteristics through a range of wet well levels and pump speeds, the system uses the full range of pumping data available to optimize performance. It can be retrofitted to existing stations or installed in new stations.

Active Front End (AFE) drives use two power sections. An active rectifier is used to minimize the amount of harmonic distortion reflected to the power grid by drawing nearly sinusoidal current from the power grid. Standard 6-pulse rectifiers used in most drives create harmonics (e.g.5th, 7th, etc.) that can generate anywhere from 30 to 100 percent current distortion. The active rectifier used in the AFE drive creates cancelling harmonics that effectively eliminate those that would be created in a standard 6-pulse drive.

Industry analysts predict that in the near future, most motors will be controlled by variable frequency drives. Here are the reasons why.

A successful infrared program involves planning and action. This article outlines steps that will help you implement a thermography program.

The third annual Product Innovation of the Year award was hotly contested again this year. The contest examined products entered into the marketplace between September 1, 2010 and August 31, 2011.

Control panel products enhance smooth operations.

Read how WirelessHART can be implemented in large process plants despite the distances needed for the network.

Today's lean maintenance staff needs pump and motor protective devices that diagnose and predict problems before they become acute.

As pump users, we often have to deal with fuzzy concepts, such as: What is low flow? When are vibration levels too high? When is suction specific speed value too high? When is a pump's energy level high?

The details of a mass-based chemical injection system for an application that requires critical dosing of a trace chemical into a continuous flowing fluid.

Enveloping is a tool that can give more information about the life and health of important plant assets. It is primarily used for early detection of faults in rolling element bearings and gearboxes. Enveloped acceleration is an especially valuable parameter to trend, as the progression of machine condition can be evaluated. Armed with good information and assisted by service experts, plant engineers can be confident in the proper operation and management of the important assets in their care.

Wireless control and monitoring are a vital part of pump systems.

Precision laser alignment can help end users avoid multiple problems in wind turbine applications.

Pulsation and water hammer can be limited with proper forethought and equipment.

Have you ever wondered why a motor manufacturer would state that many of their 60-Hz motors will operate on 50-Hz power as long as you reduce the nameplate voltage by 1/6?

SCADA can be utilized for remote data acquisition, but because it is primarily a real-time control system, the user must make significant compromises to use it for this purpose. These compromises include cost, data integrity, flexibility, convenience and control of the task. Here are some considerations to think through.

Explore best practices for securing SCADA systems in remote sites. This article addresses threats and corresponding implementation measures with a focus on SCADA RTU installations and the processes they monitor and control.

Mechanical pressure gauges, which require no external power, provide an affordable and reliable source of accurate pressure measurement. Using the criteria below can help maximize gauge life.

Named after frontiersman Kit Carson, Carson City, Nev., is known for its fresh air, rugged natural surroundings and its proximity to the casinos of Reno and skiing in Lake Tahoe. Carson City, the capital of Nevada, has been a self-governing municipality since 1972. The Carson City Public Works Dept. manages all the water for Carson City and County. Its mission is to be completely self-sufficient-acquiring, using and reusing 100 percent of its own water.

How a monitoring alarm system with control and shutdown capabilities prevented costly pump damage and environmental hazards and made the job of the pump operator safer and easier.
