Case Study: Upgrade Your Pumps for Reduced Steam Consumption

A major unit at a petrochemical facility in Asia recently upgraded a Byron Jackson boiler feed pump with Vespel® CR-6100 non-metallic wear rings. This pump is driven by a single stage steam turbine. The objective of the upgrade was to reduce steam consumption. The case wear rings in the 9 stage pump were upgraded to Vespel® Read the full article…

Diesel Charge Pump Case Study

DuPont™ Vespel® CR-6100 helps the pump survive and keep pumping. The Diesel Charge Pump A refinery in North America experienced recurring issues with their diesel charge pumps. The pumps provide feed into the refinery HDS unit. Loss of feed to the unit can result in reduced refinery production and significant losses. The refinery has 3 total pumps Read the full article…

Case Study: Repeat Failures of Boiler Feed Water Pumps

Boiler Feed Pump Seizing Problems The low lubricity of boiler feed water along with operational challenges can lead to pump seizures. 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…

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…

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…

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…

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. Over the Read the full article…

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). Read the full article…

Save Money on Your Next BB3 Pump Overhaul

How to re-use the worn wear rings for better performance Axially split, between bearings multi-stage pumps (API Type BB3) are used for some of the most important services in the hydrocarbon processing industry–charge pumps, boiler feed pumps, and product shipping/pipeline pumps. The repair of these pumps is a great opportunity to upgrade with Vespel® CR-6100 Read the full article…
