Power Plant Switches to DualPac® 2211 Packing to Reduce Plunger Pump Leakage
Chesterton products – Chesterton DualPac® Packing Technology
A customer in the power industry was facing leakage problems within their plunger pumps due to their original PTFE packing failing. With plunger pumps being quite difficult to seal due to high pressures, Chesterton experts instantly recommended the DualPac® Packing due to it’s abilities in harsh environments. Leaks drastically reduced and the customer was satisfied with the results.
Products featured in this case study:
A power plant in the Czech Republic has two plunger pumps pumping wastewater. The customer faced a lot of problems with leakage and has housekeeping issues as a result. They were using a PTFE packing, supplied by a service company, that clearly wasn’t performing well. The MTBR was +/- 1 month. Temperature: ambient. Pressure: 15 bar.
Plunger pumps are quite challenging to seal, due to the high pressures involved and the fact that the packing set is continuously pushed linearly from one side to the other. The customer clearly wanted to solve the leakage problem and the short MTBR.
The solution was 12 mm DualPac® 2211 Packing installed in a configuration as shown below—six rings of packing installed.
After eight months, the packing was still running with no leakage.
Total Net Annual Savings: $857 US ($1100 AUD) per application per year.
The customer bought DualPac® 2211 Packing for other applications as a result.
