How do you avoid the problem? Or, if it happens, what is the best way to solve the problem? This case study is about repeat seizures of two, new, 1.2 MW boiler feed water pumps operating Read the full article… This entry was posted in Boulden News, DuPont™ Vespel® CR-6100 Solutions, Pump efficiency and tagged boiler feed water pumps, boulden, composite wear components, CR-6100, dupont vespel cr-6100, improve pump efficiency, PERF-seal, Pumps With Composite Wear Components, reducing pump seizure, upgrading pumps, Vespel Case Study, Vespel CR-6100, wear rings on September 8, 2021 by Patrice Isdahl. Case Study: Upgrade of Boiler Feed Water Pumps Last week, we wrote about a boiler feed pump case history where the customer paid dearly because they didn’t use Vespel® CR-6100. Repeated failures due to pump seizure led them to increase the clearance at the wear rings, resulting in a lifetime of lower efficiency and higher operating costs. Published right next to that unfortunate history was Read the full article… This entry was posted in Boulden News, DuPont™ Vespel® CR-6100 Solutions, Pump efficiency and tagged boiler feed water pumps, case wear rings, composite wear components, composite wear rings, CR-6100, dupont vespel cr-6100, pump wear rings, Pumps With Composite Wear Components, Vespel CR-6100 on August 16, 2021 by Patrice Isdahl. A Look at Life Cycle Costs – Part 3: Unplanned Events Today we take a final look at the above graph. We have already looked at Energy and Maintenance costs. Today we look at Operating, Environmental, and Downtime Costs. When you upgrade pumps with composite materials like Vespel® CR-6100, Boulden B-Series, or Metcar® composites, you eliminate the metal-to-metal contact points in the pump, which essentially eliminates Read the full article… This entry was posted in Boulden B-1050, Boulden News, DuPont™ Vespel® CR-6100 Solutions, Metcar M-161, Metcar M-310, Pump efficiency, Vertical Pump Shaft Bearings and tagged case wear rings, composite wear components, composite wear rings, CR-6100, dupont vespel cr-6100, pump seized, pump wear rings, Pumps With Composite Wear Components, Upgrading Pump Parts with Composite Materials, upgrading pumps on July 30, 2021 by Patrice Isdahl. A Look at Pump Life Cycle Costs – Part 2: Energy Savings Today we continue our look at the above graph. Last week we looked at maintenance costs. Today, we look at energy consumption. When you upgrade pumps with composite materials like Vespel® CR-6100, Boulden B-Series, or Metcar® composites, you can reduce the energy consumption. Reducing the energy consumption of the pump creates continuous and long Read the full article… This entry was posted in Boulden News, DuPont™ Vespel® CR-6100 Solutions, Pump efficiency and tagged boiler feed water pumps, boulden, charge pumps, CR-6100, dupont vespel cr-6100, improve pump efficiency, pump wear rings, throttle bushings, Vespel, Vespel CR-6100, vespel stock sizes on July 28, 2021 by Patrice Isdahl. A Look At Pump Life Cycle Costs – Part 1: Maintenance Most of us have seen a graph similar to the one above. Over the life of an engineered pump, the energy consumption and maintenance will account for the majority of the life cycle cost. So, if you can make your pumps more efficient and more reliable, you will save a lot of money.

Solving Vertically Suspended Barrel Pump Failures Between 2011 and early 2012, a refinery suffered repeat failures of a pair of vertical pumps. Looking at the cross section, you can see this is not an ordinary pump. It is essentially a BB5 multi-stage diffuser pump mounted vertically. The pumping conditions are also uncommon–0.61 specific gravity hydrocarbon running at 300 F (149 C).

Improve Your Wastewater Pump Reliability Better shaft bearing materials lead to longer life Review Vertically suspended pumps with separate discharge (API Type VS4, shown in Figure 1) are generally used for sump pumps or waste water pumps. These pumps are a frequent source of headaches. The shaft bushings wear out leading to chronic repairs. Even though these pumps are in Read the full article… This entry was posted in Boulden B-1050, Boulden News, DuPont™ Vespel® CR-6100 Solutions, wastewater shaft bearings on February 18, 2021 by Patrice Isdahl. Comparing Pump Component Composite Materials There is one material property that can tell you a lot about how a composite material is likely to perform in a pump: The coefficient of thermal expansion (CTE). If the value is too high, the material can deliver inconsistent results in challenging services. Why CTE? A low CTE is essential for reliable performance because components Read the full article… This entry was posted in Boulden B-1050, Boulden News, DuPont™ Vespel® CR-6100 Solutions, Vertical Pump Shaft Bushing and tagged boulden, composite wear components, improve pump efficiency, upgrading pumps, Vespel CR-6100 on February 11, 2021 by Patrice Isdahl.
