7.6.1  

 Mechanical Seal

The mechanical seals used as standard in the L series pumps are of the unbalanced internal single spring type. This spring 

produces the minimum contact force between the sealing surfaces of the rotating and stationary units. The stationary unit is 

mounted on the union body in an elastomer cup. Its design allows the sealing surfaces to remain in contact, even if natural 

wear or axial and radial oscillations occur in the rotation of the unit. 

Newly installed mechanical seals may leak liquid between their sealing faces, this is small and should diminish with some 
time of operation. Mechanical seals do not require maintenance, but when they have completed their service life, they 
should be replaced completely with new seals.

When  a  seal  is  to  be  installed,  always  remember  that  it  should  be  done  with  the  utmost  care  and  cleanliness,  so  the 
contact protection between the two sliding surfaces should be removed only at the time of assembly. . 

These seals are composed of the following elements: 

Rotary Unit 
Spring (Stainless Steel) 
Metal Basket (Stainless Steel) 
O'Ring (Buna N or Viton) 
Sealing Face (Graphite) 

Stationary Unit 
Sealing face (Ceramic)
O' Ring (Buna N or Viton)
