Houston, Texas (PRWEB) September 16, 2014
Recently, high-tech firm Kalsi Engineering announced the testing results on its rotary seals. The announcement reveals the Sugar Land-based company's overall dedication to optimal performance from its products.
Hydrodynamic rotary seals comprise a huge part of Kalsi's product line-up. The company initially developed them to resist the harmful effects of oilfield downhole drilling environments. The high durability level of Kalsi rotary seals can be attributed to their ability to handle high differential pressure. Additionally, they use hydrodynamic lubrication to considerably slow down or reduce wear on the seal and shaft, thus the prefix "hydrodynamic." Rotary seals can be used in both low and high pressure installations, which include construction and hydraulic swivels, mud motors, oilfield cement and submerged dredge pumps, rotary valve actuators, and underwater vehicles.
According to Kalsi Engineering, their rotary seals provided excellent results in recent tests concerning differential pressure sealing technology. In an earlier blog at Kalsi's website, there was discussion of an ongoing test with 7,500 pounds-per-square inch (PSI) differential pressure with a seal that achieves 300 revolutions per minute (RPM) on a 2.75 shaft with dynamic run-out. In a video of the test, which takes place in the company's Rotary Testing Lab, rotary seals are tested with a differential pressure of over 3,000 PSI at 750 RPM on a 2.75 shaft with dynamic run-out.
Achieving a high differential pressure ensures that the seals are better handlers of severe service applications. The technologies used for this testing are the floating back-up ring assembly and the Extra Wide Enhanced Lubrication Kalsi Seal with an integral plastic lining. The patents are currently pending.
