180PR Pumping Ring Seal - High Capacity Pumping Ring Seal for Maximum Heat Rejection and Reliability.

• Low Cost, Highly Efficient Cooling. Pumping ring circulates only stuffing box fluid in a closed loop cooling system reducing re-heat costs.
• High Temperature Sealing with Standard Materials.
• Chemical precipitation minimized.

Cooling for Ideal Face Lubrication

• Effective cooling maintains seal face flatness, provides adequate liquid viscosity for seal face lubrication and prevents volatile fluids from vaporizing.
• Smaller heat exchanger required because the overall heat load is smaller.
• Eliminates the need for external injection of cold condensate

Independent Pumping System

• Reduces pressure differential compared to other cooling arrangements resulting in lower flow velocities, less susceptible to clogging and erosion and elimination of in-line orifices.
• Thermo-siphon performance for hot stand-by conditions even when the pump is not running, or the plant is idle, the seal is shielded from the damaging effects of heat.
