Even though the Sicoma MOSAP10 seal support ring is a static component, it sets the reference position for every dynamic element in the MOSACOM system. When its seating faces are damaged, worn or distorted – or when the part is bent or incorrectly machined – several issues can occur:

• MOSAP9 connecting ring and internal O-rings can move axially instead of staying locked in place.

• This “floating” condition changes the compression on the O-rings and breaks the sealing line.

• Concrete slurry and wash water can enter the housing more easily, accelerating wear in nearby seals and bearings.

• If the locking unit loses its reference, the shaft clamping can loosen, risking serious damage to the mixer shaft and arms.

Replacing a worn or deformed Sicoma MOSAP10 seal support ring with an OEM equivalent Conspar spare part before this stage helps protect more expensive Sicoma mixer spare parts in the sealing group and reduces the chance of long, unplanned downtime in high-volume ready-mix plants.

The MOSAP10 seal support ring is designed for SICOMA MAO 3000/2000 twin-shaft concrete mixers that use the MOSACOM shaft sealing system. It is not a generic spacer or bushing; the 123 mm ID and 168 mm OD are specific reference dimensions for this Sicoma seal support body.

Typical application context: Heavy-duty Sicoma twin-shaft mixers working in high-volume ready-mix concrete batching plants.

To avoid ordering the wrong concrete mixer spare part, confirm the old part markings (MOSAP10 / 0228G0140L1) and cross-check the main dimensions with calipers or OEM drawings.

• Preparation:
  Inspect the internal bore and O-ring grooves, removing cement build-up, rust and burrs so all sealing surfaces are clean and smooth.

• Seating technique:
  MOSAP10 is a precision-machined steel body. It should be pulled or pressed into place evenly; hammer blows on one side can ovalise the ring and distort the seal housing.

• For critical overhauls on SICOMA twin-shaft mixers, installation and inspection should be carried out by technicians familiar with the MOSACOM sealing group layout.

• Fastening:
  When tightening the M6 screws (VB093) or equivalent fasteners, follow a cross / star pattern and use the recommended torque to distribute load evenly.

• System check:
  After assembly, verify that MOSAP9, the O-rings and the locking unit sit squarely, and that the shaft turns freely without rubbing on the seal support ring.
