MPS 896® SPECIAL MIX

For lip seals against WATER INGRESS

Description

FOR LIP TYPE SEALS WITH SEAL REVITALISER
An effective additive for Stern Tubes and Bow Thrusters can also be used in CPPs, Rudder Shafts and Rudder Machines

how to apply mps 896 special mix

The MPS 896 Special Mix paste must be injected in its concentrated form directly to the aft seal chamberss. It is necessary to have a suitable pump for application. Lindemann can supply a high pressure pump, which suits the 20 kg drum, for easy application. The pump can later be used for other purposes.

Description
MPS 896 Special Mix has been developed specifically to stop water ingress in systems with lip type seals.

MPS 896 Special Mix contains a very high amount of Teflon, which due to friction will embed the wear surfaces during operation, repairing minor defects in the contact surfaces between shaft and seal. This will prolong the life time of the seals.

Working principle

Dynamic barrier in aft seal chambers

In addition to high concentration of PTFE, MPS 896 Special Mix contains another additive, which gives the paste different structure and makes it cling to the rotating shaft with a firm grip.

The „firm grip“ on the shaft ensures that the higher level of PTFE is interlocked right in front of any given slip between the seal and the shaft, offering a tougher sealing effect that will withstand greater forces from the sea.
The paste’s seal revitalizing additive preserves or restores flexibility of the rubber seals without swelling.

BENEFITS
  • Lubrication with solids
    MPS contains high concentration of PTFE and Bentonite.
  • No water/oil emulsion
    MPS does not emulsify with oil or water.
  • Compatible with most oil types
    Oil is used as a carrier for solid particles, PTFE and Bentonite.
  • Broad working temperature range
    MPS tolerates temperatures from -30° C to  260° C.
  • MPS contains seal revitalizing additive
    Compatible with FKM and NBR elastomers.
    MPS restores seals elasticity without swelling.
  • Surface treatment
    MPS polishes surface and fills in cracks of up to 2 mm.
    MPS provides static lubrication due to surface fluorination.
  • Anti-corrosion and EP properties
    MPS enhances corrosion protection and allows increased loads.
Typical application areas
MPS 896 Special Mix is specially designed to re-establish the sealing effect in defective lip seals systems with water ingress.
Compatibility
  • MPS 896 Special Mix will work equally well with most materials e.g. bronze, chrome, stainless steel or brass and rubber, asbestos and plastics.
  • MPS 896 Special Mix is compatible with NBR and FKM elastomers.
  • MPS 896 Special Mix can be used as an additive with both mineral oil and EALs.
TREATMENT RATE
Apply 100% of MP 896 Special Mix to aft seal chambers only.
Please, consult Lindemann team for application instructions and the necessary quantity.
