In today's growing industrialized market, the need for reciprocating pumps is increasing daily. As technology drives modernization, the demand placed on the pumping systems is continually rising.

One of the most neglected tools in the vibration analysis toolbox is phase. This neglect is partially due to the extra time and effort often necessary to collect the information. Many analysts are also not properly trained in phase measurement and analysis.

Last month we reviewed the pump selection criteria for a typical constant pressure-variable flow (Cp-Vf) application that utilized variable speed (VFD) control. This month we will explore an application where pressure varies in proportion to a change in flow.

Economic pressures to minimize production downtime and improve operating efficiency are increasing the emphasis to accomplish on-site problem detection, analysis, and resolution as fast as possible. These requirements place a great deal of pressure on maintenance personnel to have all the right tools readily available in one place.

State and federal requirements increase the need for pump monitoring and control.

Balancing is essential for minimizing vibration, increasing bearing life and minimizing downtime and repair costs. Follow the guidelines from these standards to balance centrifugal pumps properly.

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

Picture a manufacturing enterprise with plants in multiple locations around the world. Using a single automation platform that handles discrete, process and motion control with common programming, human machine interface (HMI) and standards-based networks, a night shift operator gathers and logs data on product quality from his production line.

Electric drives are used in various applications in the oil and gas industry for varying motor speeds driving critical components, including pumps, fans and compressors.

The level transmitter is a small but vital component in a sewage lift or pump station that helps maintain system integrity and avoid unwanted spillage.

While driving a car with the gas pedal to the floor and then controlling your speed using the brake is obviously inefficient, many facilities use the approach for pump control. Flow control with throt­tling or restrictive devices sacrifices energy efficiency and results in unnecessary costs. However, with an understanding of basic principles, an analysis of the specific application, information about available control solutions and evaluation of technologically advanced equipment, facilities can make a quantum leap in improving the efficiency and econ­omy of pumping operations. pump efficiency

Pressure gauges are an important indicator of whether a system or component is operating correctly. Pressure gauges generally require little to no maintenance, other than periodic calibration. However, if gauges require minimal maintenance, why do some seem to continually wear out?

The 4-20mA current loop is used to transmit analog data representing various process variables like level, pressure, temperature or flow. Although conceptually simple, a 4-20mA current loop can be tricky to troubleshoot. Current flows in a single direction through each device in the loop.

Even though control technology has become an integral part of many pumping systems, over half of our readers have not expressed much interest in pump controls. I think I know why - today's controls are simply not as intuitively understandable as they once were. Who wants to read about the advantages of PID control without a basic understanding of P, I, and D itself?

Here is a primer on the proper locations for surge protection in water and wastewater facilities.

Lindmore Irrigation District uses Ethernet radios to improve SCADA communications system and pumping efficiency.

A Nashville-based hunting club required the flooding of several acres of land. A shallow area approximately 1.5-ft deep needed to be flooded to help attract wild game.

Frequency analysis is an important method of vibration analysis.

This article explores the use of condition monitoring at the UPM-Kymmene's Wisaforest pulp and paper mill in Finland. Production capacity is 800,000 air dried tons per annum (ADt/a) of pulp and 180,000 ADt/a of kraft and sack papers.

Water chemical compatibility and electrical interference are two major challenges for control systems. Two major sources of fresh water can limit the performance of the control system.
