- Closed barrier fluid system compliant with all requirements of API 682, 4th edition.
- For double mechanical seals (Arrangement 3). The barrier fluid pressure is higher than the pressure in the pump’s seal chamber. The barrier fluid pressure is generated by a pre-loaded bladder accumulator.
- Pressurisation by the bladder accumulator prevents the pressurised gas from dissolving in the barrier fluid, especially at high pressures. An integrated cooler (optionally available with water cooler or air cooler) ensures an optimum operating temperature in the space between the two seals.
