About Mechanical seal type 10t
A complete externally mounted PTFE seal with bellow integrated PTFE face for use in extremely corrosive applications such as high concentrations of acids, salts, strong oxidizing and reducing agents, and chemically active organic compounds
Design Features mechanical seal type 10t
Non-pusher bellows feature eliminates sliding contact with the equipment shaft or sleeve during operation
• The outer-end of the seal bellows is clamped to the shaft or sleeve surface, and the bellows convolutions extend to compensate for seal
face wear
• All surfaces contacting the liquid being sealed are made of chemically inert materials. Metallic components — springs and clamping ring — are located outside the pump stuffing box, isolated from the process liquid
• The Type 10T face is not replaceable, but the seal has a higher-duty pressure and transient pressure rating than the Type 10R
• The Type 10R seal face is replaceable and can be supplied in hard materials making the seal suitable for abrasive applications
• The seals incorporate visual wear indicators which show the initial seal setting and the amount of face wear while in service
