Some factors to consider when selecting a Double Mechanical Seal - Dry Running Non-Contact; -Dry running non-contacting (or gas lift-off) - the barrier fluid is a gas -Gas Usage rates are higher than contacting (issue for hard vacuum) -Strict run-out tolerances - suitable for your machine?

Dry mechanical seal are designed for Agitators, Reactor, Mixers, Reaction Vessels and Blowers etc. wherein shaft drive is located mostly at the top of the 

4/22 · How Graphitization Can Benefit Dry Running Mechanical Seal Faces. Graphite grains are the key to carbon/graphite’s self-lubricating ability. Thus, by increasing the graphite content

It will help you to avoid the problem of Dry Running Seals. In rigorous and realistic testing at Flowserve's R&D facility, these seals have proven to last in shut off events for over 90 minutes at 3600 RPM as shown in the graph below. Most dry running instances on site last less than 30 minutes on average.

Mechanical seal suitable for dry running. Solution for corrosive fluids are widely used in chemical industries on centrifugal pumps. Dry running version is 

Single outside mounted seal • Specially designed for Mixers, Agitators and Vessels • Dry running seal • No barrier fluid required. • Accommodates the shaft movement, vibrations and deflection. Materials : Face :Carbon, Silicon, TC Seat : SIC, TC, Metal components : SS 316/Nickel Alloys Secondary Sealing : EPR/ EPDM/Viton/GRAFOIL

Dry running conditions or high temperatures are not a problem at Vanseal. Seal manufacturers using compounds made solely of rubber material are unable to produce seals that withstand extremely high temperatures and not fall apart when exposed to a high-friction or abrasive environment. Seals made from PTFE withstand High Temperatures

Dry Running Mechanical Seals (TYPE D50/D51B ) "Dry Running Mechanical Seals" are outside mounted balanced mechanical seal, which require no shaft or sleeve step for balancing seal shows good performance in high vaccum conditions. Since no auxiliary equipments are needed for installation, it is very cost effective & economical.

Dry Running seal are designed for agitators, mixers, reactor vessels, blowers, fans, etc. and is basically used on top of the vessel. The seal face is exposed 

8/27 · Here are 8 reasons for a Mechanical Seal failing within a process. 1. Dry Running. Dry running is where a pump is operated without fluid. This means internal parts which often rely on the pumped liquid for cooling and lubrication are subject to high amounts of friction and heat leading to prompt failure. Failure can happen in seconds and so it
