About Mechanical seal type 10r
A complete externally mounted PTFE seal with exchangeable face insert 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 10r
• 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
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
