A customer in an oil refinery plant was sealing lobe pumps with basic packing only lasting a single week due to high pressures and abrasive clay inside the oil. The customer wanted to upgrade their packing to a more durable and high-quality product. Luckily, Chesterton DualPac® 2211 Packing Technology is the perfect option for the application!

Challenge

An oil refinery in the Czech Republic is sealing lobe pumps with packing. The lobe pumps are pumping oil slurry, 40°C, from 2 – 10 bar, into a filter. The medium consists of oil and up to 30% of clay. Packing mean time before repair (MTBR) is only one week. Sleeve MTBR is two years. The application is challenging to seal due to the increasing pressure and abrasive clay inside the oil. Increasing pressure due to filter clogging causes different leakages on the start and on the end of the pumping cycle.

The lobe pumps are pumping oil slurry.

Solution

To end these ongoing issues, the customer installed 8 mm DualPac® 2211 Packing Technology in a configuration as shown below. The packing ran at least for four months with no leakage on the start and low leakage on the end of pumping cycle.

The configuration of the Chesterton solution.

Results

Change in MTBR: 12X to date

Total Annual Savings: $1800 AUD (1,070 EUR) per pump

Chesterton DualPac Packing Technology improved MTBR.
