Seal Support Ring 123×168×66 mm – SICOMA MAO 3000/2000 – MOSAP10

Seal Support MOSAP10 is a steel ring serves as the main structure of the MOSACOM sealing group, which is an essential part of the Sicoma twin shaft mixer spare parts collection.

The MOSAP10, unlike moving seals, does not perform sealing on its own. It instead offers a firm and crafted casing for the MOSAP9 connecting ring and the related O-rings. This setup helps maintain the smooth running of concrete production processes.

It bears the axial loads of the locking unit and establishes a fixed reference point within the housing. By holding the sealing elements in their strictly correct axial position along the shaft it prevents geometry distortion in high-capacity batching plant mixers.

Why replacement matters?:

When the MOSAP10 fails, some severe outcomes may occur as follows:

• The internal O-rings and connecting ring (MOSAP9) shift axially.
• This "floating" condition leads to an immediate loss of seal integrity.
• Concrete slurry ingress accelerates.
• The shaft locking mechanism may loosen, risking catastrophic failure of the mixing arm assembly.

What to check before ordering:

This component is unique to Sicoma mixer models that utilize the specialized MOSACOM system.

• Identification: It is not a standard "spacer bushing." The 123 mm ID and 168 mm OD are critical dimensions set in stone for proper fitment.
• Recommendation: Measuring the old part with calipers or verifying the mixer serial number on SICOMA drawings to ensure this is the correct Sicoma mixer spare part of the unit.

Installation notes:

Sequence and precision are vital for this static component.

• Preparation: Before installing the MOSAP10, inspect the O-ring grooves and internal bore for perfection.
• Technique: Avoid hammer blows when seating the part; this is precision-machined steel, and brute force will ovalize it, ruining the seal.
• Fixation: When tightening the M6 screws (VB093), use a torque wrench and a star pattern to distribute the load evenly across the body.
• System Check: If the support seats are crooked, the entire MOSACOM system will fail.
• For critical maintenance, installation should be performed by a qualified technician.
