A modular component system is ideal for a flexible engineered approach to each application. The need for exotic wetted alloys, various seal face combinations, alternate ‘O’ ring compounds, differential secondary fluid pressures, temperature control and barrier fluid containment systems are some of the design parameters encountered.

Highly corrosive applications aggressively attack Stainless Steel. Corrosion is usually limited to the wetted components; namely the inboard rotary, a portion of the shaft sleeve and a section of the gland. Procurement of exotic alloy seals often results in long lead times and supply delays.
