Mixing of Viscous Materials Under Pressure

Roben Mfg, Inc. fabricates agitated reactors for mixing viscous materials under pressure where thorough homogenization of high-viscosity fluids requires specialized agitation at elevated pressures. Our high-viscosity pressure mixing vessels deliver effective agitation ensuring uniform composition and properties throughout challenging viscous batches.

Agitated Reactors for High-Viscosity Pressure Mixing

Mixing viscous materials under pressure presents unique challenges requiring specialized vessel and agitator designs. High-viscosity fluids resist mixing, develop dead zones, and require substantial power input for homogenization. Operating under pressure adds requirements for robust shaft seals or magnetic drives capable of transmitting high torque while maintaining pressure containment.

Frequently Asked Questions

1. What viscosities can your reactors effectively mix under pressure?

Our high-viscosity designs effectively mix materials exceeding 1,000,000 cP under pressure. Anchor, helical ribbon, and combination impellers maintain mixing at extreme viscosity. Power requirements increase substantially with viscosity. We design agitation systems for your specific viscosity range and mixing requirements.

2. How do you seal high-torque agitators for pressure service?

High-torque pressure applications use heavy-duty mechanical seals designed for the combination of pressure, speed, and torque. Double seal arrangements with barrier fluid provide additional safety. For ultimate containment, magnetic drives transmit torque without shaft penetration, though torque limits must be considered.

3. What impeller types work best for high-viscosity pressure mixing?

Anchor impellers provide wall coverage and prevent buildup. Helical ribbon impellers create axial circulation throughout the vessel. Combination designs incorporate both features. Some applications benefit from planetary or double-planetary motion. We select impeller configuration based on your viscosity profile and mixing requirements.
