Introducing Wilden® Chem-Fuse diaphragms now available for industrial markets. These integral piston diaphragms (IPDs) solve many of the critical issues faced by industrial companies that use conventional diaphragms while incorporating the core patented technology of Wilden Pure-Fuse diaphragms. Benefits include: • Elimination of a potential leak point at the outer piston when pumping critical or […]
Among DESMI’s innovative approaches is ‘Pumps-for-free’: a cash flow-neutral investment concept for energy-saving solutions. It’s a unique financing package, enabling ship-owners to energy-optimize their vessels while repaying the investment through savings, typically in 14 to 18 months. The financing schedule is linked to the ROI/payback period, with quarterly payments. DESMI offers a wide range of […]
Selecting valves for cryogenic applications in liquefaction plants can be quite tricky. Application expertise, along with a high quality valve, is needed in order for the valve to operate effectively and efficiently in these demanding facilities. This article presents the latest in valve innovations for liquefaction plants. The valves used in liquefaction encounter natural gas […]
GRAFILIT® IQ is an engineered graphite-based composite gasket material endowed with mechanical reinforcement and anti-stick property, making it suitable for high temperature applications. This heavy-duty material has improved surface load resistance (in particular for cycling operations) and blowout resistance.
While the composition of wastewater differs from one treatment plant to another, overall, wastewater in the U.S. has become heavier and more difficult to process. There are several options for engineers, operations and maintenance managers to minimize the risk of breakdowns resulting from new challenges in wastewater transport, but each requires a deeper look at […]
Most experts agree that Severe Service Valves are identified by applications, and that these applications are challenging to the valve’s ability to provide a minimum acceptable level of performance over a minimum acceptable duration. However, at this time, no clear or universal industry definition or mechanism exists to describe and accurately define severe service valves […]
Variable Frequency Drives (VFDs) are often used in wastewater stations that transport sewage. They are used to control the flow of sewage through the pumps and help wastewater treatment plants achieve the required flow. Like any piece of equipment, it must work with the whole system to be truly effective. This article, from Horst Sturm […]
If you’ve ever led a Root Cause Analysis (RCA) Team, you will likely relate to the responses and discussions included in this study, which was conducted and compiled by Robert J. Latino, CEO, Reliability Center, Inc. Effective RCA analysts have a tough job with many barriers to overcome. For those ‘driven’ analysts who rise to the […]
Unique features in the Ring Damped Valve design allowed a gas gathering facility in North Dakota to run their Dresser Rand RDS-4 reciprocating compressor at higher lifts than traditional plate valves, resulting in maximum flow area. Increased flow area significantly reduces the horsepower required to move gas, thereby increasing energy efficiency. This case study shows […]
It is a topic that can critically affect the profitability of food and- beverage, pharmaceutical and cosmetic manufacturers, from the most basic production-line level on through entire plant efficiencies…even overall corporate performance. As belts are tightened, the operators of these manufacturing facilities have been forced to implement new ways to meet established production quotas while […]
In Part 3 of KSB’s article “Global Wastewater Challenges Place Pressure on Aging Infrastructure”, Horst Sturm shares a great amount of detail about wastewater pump stations and the design aspects that must be considered when addressing current wastewater challenges, such as change in sewage composition and clogging, etc. This article discusses the following aspects: Type of […]
