product range:
TiTAN series single-stage and two-stage motor-mounted liquid ring vacuum pumps,
Vmax oil-sealed liquid ring standard vacuum pump systems.
AquaSeal water-sealed liquid ring vacuum pump systems are liquid ring vacuum pump packages using water as the seal-liquid. The systems (in capacities ranging from 15-6,000 CFM) are designed to operate for no recovery, partial recovery or full recovery (with heat exchanger).
ChemSeal liquid ring vacuum pump systems are liquid ring vacuum pump packages using the solvent recovered from the process as the sealing liquid. The units are designed as full recovery systems with heat exchanger to cool the sealing fluid.
The systems are available in a capacity range from 15-3,000 CFM, operate at vacuum levels down to 0.5 Torr and, with the addition of condensers, can recover close to 100% of the solvent.
