When leakages are led back into the process, environmentally harmful media is prevented from escaping. Areas of use are pumps with stuffing box packings, lip seals and single mechanical seals used in chemical and petrochemical sectors. The system comprises a mechanical seal, a leakage trap and a pump unit. Disposal of quenching fluid contaminated with product leakage is no longer necessary. An outboard, gas-lubricated mechanical seal (grooves on the inside diameter) takes over the sealing function and prevents uncontrolled leakage if the primary seal should fail. The system can be retrofitted and needs no auxiliary power. Recirculation with intake pressure >1 bar is possible. Technical data: temperature max. 200 °C, nominal pressure 16 bar, max. recirculation flow 6 l/h.
