Product Description
 
Product Description

QT SME external balanced seals
An external mechanical seal with non-metallic components in contact with the media being sealed therefore able to operate in corrosive and chemical applications. Suitable for use with a number of stationary face arrangements.

External clamping 
Easily set to the correct working length, enabling pump efficiency 
adjustments to be made without dismantling the pump.
 
Visual examination 
Visible spring gap allows monitoring of face wear. 

Positive drive lugs 
Drive forces are evenly distributed around the rotary face to reduce stress. 

Non-metallic wetted parts 
No metal parts in contact with pumped media, therefore able to 
operate in corrosive applications. 

Balanced 
Hydraulic balance is achieved within the seal design and does not require a stepped shaft. Face loading is reduced to give cooler running and longer seal life. 

Anti-clog 
The dynamic O-ring moves onto a clean area as seal faces wear. Components remain free for longer seal life. 

Secured rotary face 
Shrink fitting improves durability and face retention under extreme operating conditions.

Metal parts:316 Stainless Steel as standard, other materials also availab

O-rings:vit® (Flurocarbon) or Ethylene Propylene (EPR) as
standard.  Aflas®, Kalrez® and other elastomers available to order

Rotary face:Carbon, Silicon Carbide or Tungsten Carbide as standard. Antimony Carbon available on request.

Temperature:-30oC to 260oC (-22oF to 500oF) dependent upon 
specified elastomer and sy711mmstem configuration

Pressure limits: HG Vacuum to 30 Bar(-28" HG - 440 PSI)
External clamping
Easily set to the correct working length, enabling pump efficiency adjustments to be made without dismantling the pump.
Positive drive lugs
Drive forces are evenly distributed around the rotary face to reduce stress.
Springs out of fluid
The Alloy 276 springs are not in the pumped fluid where they could corrode or clog, so remain effective for the whole of the seal life.
