4.4.3.2 Double Mechanical Seal Installation 

 
Place the 

Stationary Seal O-Rings (primary & secondary)

 in the rotor housing 

seal bores and the 

Flush Housings

. Only lubricate these o-rings with water or 

alcohol. Push the 

Stationary Seal Faces (primary)

 into the rotor housing so that 

they seat flat with the step in the housing.  Push the 

Stationary Seal Faces 

(secondary)

 into the 

Flush Housings

 making sure the o-rings seat properly. Do 

not use objects that will scratch the Stationary Seal Faces’ seal surface to push 
them in. Place a product compatible lubricant on the sealing surface of the 

Stationary Seal Faces

. 

  
While the rotor housing is lying flat with the cavity facing down, stack the seal 
components on the 

Stationary Seal Faces (primary)

.  Begin with 

Rotating Seal 

Faces (primary)

, slotted sides up.  Place the 

Rotating Seal O-Rings (primary)

 

into the 

Rotating Seal Faces (primary)

.  Next, place the 

Drive Collars

 into the 

the 

Rotating Seal Faces (primary)

. Making sure to align the slots with the pins, 

push the 

Drive Collar

 gently to seat the o-rings.  Place the 

Rotating Seal O-

Rings (secondary)

 on the 

Drive Collars

. Align the slots with the pins, and push 

gently to seat the o-rings.  Place the 

Flush Housings

 over the stacked components, 

rotating them to make sure one set screw will be visible through the port holes in 
the Flush Housings.  Push the housings down gently. Screw in the 

Bolts 

and hand 

tighten.  Lubricate the plastic mounting sleeves and slide them, tapered end first, 
into the seals.  Tighten the 

Bolts

.  Leave the sleeves in the seals and 

proceed to  

section 4.4.5 to complete the installation.
