摘要： A seal support system for a mechanical seal includes a system vessel for containing barrier fluid. Closed loop pipe work connects the vessel to a mechanical seal with a device provided for feeding barrier fluid to the system vessel. A further vessel is provided that is able to be in fluid communication with the system vessel. The further vessel may be provided with an elastomeric membrane, which may be filled with a gas under pressure to an extent required to allow for the effect of the highest anticipated temperature which might occur in a particular application.

摘要： A mechanical seal assembly has rotational and stationary sealing members) and a drive unit, which is axially adjacent one of the sealing members. An energizing member urges the drive unit towards the sealing members. A retainer axially and radially retains one of the sealing members. The drive unit is in contact with one of the rotational and stationary members by way of contacting surfaces which are in the range of 1 and 20 light bands of flatness, inclusive.

摘要： An annular seal cavity throat bushing includes an inner annular surface having a substantially latitudinal channel with the channel being provided with at least one orifice to allow fluid communication between the inside of the bushing and the outside of the bushing. The bushing is further provided with at least one groove extending substantially longitudinally from one end of the bushing to the channel. The groove has at least one tapered edge which increases the width of the groove along its length.
