Extra Wide Hybrid mud motor seal that fits in existing mud motor housings

Kalsi Engineering is excited to announce successful laboratory testing of an Extra Wide Hybrid seal that is a drop-in replacement for the 507-series mud motor seal. This Extra Wide Hybrid Seal fits in the same groove as the 507-series seal and has performed very well at pressure and temperature conditions that a 507-series seal fails at in just hours. See below for a summary of the test results.

As a refresher, the Extra Wide Hybrid Seal was developed to replace 507-series seals in mud motor designs that require larger extrusion gaps and high differential pressure at the pressure retaining rotary seal location. Because the Extra Wide Hybrid seal has a 1.6X wider dynamic lip than a 507-series seal it can operate at a significantly higher differential pressure. In addition to being more pressure capable, the additional dynamic lip width of the Extra Wide Hybrid Seal provides
