12 Common Technical Q&As About Type 270 Agitator Mechanical Seal

1. Q: What makes Type 270 agitator mechanical seals different from standard mechanical seals?
   A: Type 270 agitator mechanical seals feature:

• Heavy-duty spring systems for vibration resistance

• Oversized bearing supports for shaft stability

• Reinforced bellows for axial movement compensation
  These specialized designs handle 3× more vibration than conventional seals in mixing applications.

2.Q: What materials are recommended for sulfuric acid mixing applications?
A: For sulfuric acid services, we specify Type 270 agitator mechanical seals with:

• Primary faces: Silicon carbide vs. carbon

• Metal parts: Hastelloy C276

• Secondary seals: PTFE or FFKM
  This combination provides excellent corrosion resistance at concentrations up to 98%.

3.Q: How do I select the right Type 270 agitator mechanical seal for my reactor?
A: Proper selection requires:

1. Agitator shaft diameter and speed

2. Vessel pressure/temperature ranges

3. Process media characteristics
