Increase pump safety with secondary containment options
This company’s magnetic-drive pumps have a primary containment shell, which can be monitored using a patented shroud-temperature monitoring system that indicates undesirable operating conditions effectively and quickly. In many applications, this safety option is sufficient. However, certain applications require additional measures to prevent the pumped fluid from being released upon a failure of the primary containment shell. This company designed and qualified a secondary containment system (photo) consisting of a radial shaft-seal ring (RSSR), which uses a pressure or leakage detector for monitoring. It is able to withhold pressures up to 16 bars with a rotating shaft up to 3,600 rpm and for temperatures ranging from –80 up to 250°C. The secondary barrier option is available for both close-coupled or frame-mounted designs. It provides an additional safety feature and makes the magnetic-drive pumps suitable for safety-critical applications with additional requirements for a secondary containment.
