Jensen Model 500 Seal

The Jensen Type "F" Mechanical Seal is an integral part of every Series 500 Mixer. It is designed for long life at low cost. Materials of construction were especially selected to suit petroleum applications. The Series 500 has an optional packing gland in lieu of mechanical seal where preferred and/or beneficial.


Rotating Seal Face: Carbon
Stationary Seal Face: Ni-Resist 2 (High Nickel Cast Iron) Optional materials are available and include: Tungsten Carbide and Silicone Carbide.
Both sealing members are extra heavy to prevent face distortion
"O" Rings: Viton "A"
Springs: INCONEL
Housing: 316 Stainless Steel
If seal replacement is necessary, wearing parts may be purchased separately, cutting replacement cost in half.

When the Mechanical Seal is replaced, the shaft is sealed at two points. In addition to the locking seal an "O" ring seal (A) just inboard from the seal is engaged. This minimizes product loss during seal change and acts as a backup for the main locking seal. The Mechanical seal area is completely enclosed for protection from rain, dust, freezing temperatures and other undesirable conditions. A drain hole (B) is provided for seal leak detection.

Should complete seal failure occur, product loss is restricted by the shaft end bearing and by two additional close clearance rings.
