442PR Pumping Ring Seals
High Capacity Pumping Ring Seals 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
- Higher temperatures increase corrosion rates even in hot water service, impurities and treatment. Chemical precipitation is minimized.
- Cooling for Ideal Face Lubrication
- Effective cooling maintains face flatness, provides adequate liquid viscosity for seal face lubrication and prevents volatile fluids from vaporizing.
- Smaller heat exchanger required
- The overall heat load is smaller.
- Eliminates the need for external injection of cold condensate
- The need for an outside source of treated condensate is eliminated with an independent pumping system.
- Independent Pumping System
- Reduces pressure differentials compared to other cooling arrangements resulting in lower flow velocities, less susceptibility 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.
