The Basics of Reciprocating vs. Centrifugal Pumps

engineering column PD pumps Understanding the differences between these types of pumps can mean avoiding difficulties and reliability problems.

The demand for the duties that fall within the performance range of reciprocating pumps is rising. Process flows are falling while the pressures required are increasing.

Engineers are generally familiar with operating principles, performance curves and selection criteria for centrifugal pumps, but the training and knowledge around the operating principles of reciprocating pumps is not as common.

Unlike centrifugal pumps, reciprocating pumps have a stronger interaction with the system within which they sit. This is due to the pressure pulsations they generate.

If we think about any linear reciprocating motion of a piston, at some point the velocity of the piston is zero as it changes direction at the top and bottom of its stroke. This means that the pressure pulsations are much larger in a reciprocating machine than in a centrifugal machine.

Asset Monitoring Improves Reliability & Visibility

Hydro remote condition monitoring A major pipeline transmission company found itself reconsidering the effectiveness of its maintenance strategy. The company faced a challenge: optimizing asset visibility and implementing remote condition monitoring of equipment health while avoiding a high-cost investment and installation disruptions.

This particular pipeline transfers a variety of products, ranging from gasoline to jet fuel, serving customers via pump stations and storage tanks across the United States. For this customer, it is imperative to ensure that pumping assets are efficient, reliable and safely maintained consistently. The pipeline supports the needs of more than 50 cities, thus making the pumping assets critical to the availability and overall operation.

Technology plays a vital role in day-to-day operations in supporting end user activities, ensuring strict safety regulations, optimizing maintenance and providing data on equipment health. In this case, the pipeline company wanted to significantly improve and innovate upon its current maintenance approach in two ways: by monitoring asset visibility in real-time and trending data for their critical pumping equipment.

George Harris Rewarded Lifetime Achievement Award From the West Central Association

The West Central Association recently invited George Harris, President and CEO of Hydro, Inc., to be a guest speaker for their 100th anniversary.

The WCA is the Chamber of Commerce for the West Central Area. They are also a delegate agency for Chicago’s Department of Planning and Economic Development. They promote the area to encourage healthy business and a growing community.

George Harris also received an award in recognition of his contributions to the community and to the development of businesses and networking within Chicago’s West Central Area.

George has always been one of the key pillars of the community. He has lived and worked within the city of Chicago all his life and graduating from the University of Illinois with a degree in Engineering. The association was pleased to celebrate the growth of Hydro.

Though it started as a small locally based business, it is now a global company with 19 locations worldwide. Congratulations, George, on an award well deserved!

A Powerful Partnership for Obsolete and Troublesome Oil Pumps

Two trusted names in the industry have formed a powerful partnership for supporting diesel fuel and lube oil pumps. Leistritz, a global leader in the manufacturing of specialized screw pumps and technologies, has formed a powerful partnership in defeating obsolescence with Hydro.

Due to the age of pumps in the industry today, many become obsolete and unsupported by their manufacturers, while still actively in service. This poses safety issues. Through engineering and integrated manufacturing, Hydro can now meet your needs quickly, without any changes to your system. Quality assurance backed by ASME III and Z299 certifications.
