Improve Pump Efficiency
An inefficient pump will increase the overall life cycle cost of a system. It can also lead to increased energy costs and CO2 emissions. One method to improve pump efficiency is as simple as replacing existing components with components made from Vespel® CR-6100 and reducing the running clearance.
What is Vespel® CR-6100?
Made from Teflon® PFA resin and long carbon fibers, Vespel® CR-6100 is a composite material that can be machined into a virtually unlimited range of shapes. Vespel® CR-6100 offers several unique features, including the capacity to handle temperatures from -238 F to 500 F (-200 C to 260 C), chemical compatibility with most fluids and a lower thermal expansion coefficient than carbon steel. Vespel® CR-6100 is also easy to machine and install, so you can perform the upgrade in your own shop. Vespel® CR-6100 can be made into wear rings, throttle bushings and inter-stage rings for pumps.
Improve Pump Efficiency with Vespel® CR-6100
The wear parts in a pump have a significant impact on pump efficiency. These are the parts that separate high-pressure areas from low-pressure areas in the pump. Leakage across this interface diminishes pump efficiency.
Vespel® CR-6100 minimizes the risk of pump seizure and allows you to reduce the clearance at these components, generally to 50% below the original design value. The reduction in clearance reduces the leakage across these components and increases the pump efficiency.
What to do when Improving Pump Efficiency with Vespel CR-6100:
- Replace the stationary wear components with Vespel® CR-6100
- Continue using metal rotating wear components
- Reduce the wear ring clearance to 50% of the API recommended minimum
