|
|
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.
|
|
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.
|
|
Visual examination
|
Visible spring gap allows monitoring of face wear.
|
|
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
|
|
Non metallic wetted parts
|
No metal parts in contact with pumped media, therefore able to operate in corrosive applications.
