• solvent recovery
FEATURES QUALITY Designed and manufactured under the ISO 9001 standards, every component is guaranteed for the selected materials, workmanship and performance through scrupulous inspections during production stages and final testing of finished product.
FEWER COMPONENTS Through engineered design innovations and co-operation with the finest technologically advanced foundries, the pumps are manufactured with less components than typically required. Fewer parts add to the rigidity and toughness of the pumps, they are easier to assemble and maintenance is greatly facilitated.
COMPACT DIMENSIONS The conventional stuffing boxes construction is eliminated with the Pompetravaini standard design. The shaft length is greatly reduced thus eliminating the potential danger for shaft deflections and vibrations to the mechanical seals which would increase seals and bearing wear.
STANDARD MECHANICAL SEALS In keeping pace with today technology, Pompetravaini has standardized all pumps to accept unified mechanical seals to UNI EN 12756 standards. Also available upon request, are constructions with double mechanical seals (tandem or back to back) or cartridge type mechanical seals.
LARGE SELECTION OF MATERIALS In addition to the standard materials, Pompetravaini pumps are also available with special exotic materials such as Ni-Resist D2B, Hastelloy В or C, Uranus B6, etc. to meet specific requirements.
MECHANICAL RELIABILITY With the simple design of liquid ring pumps there are no reciprocating parts, no valves or sliding vanes. The impeller is the only rotating component with no metal-to-metal contact. Pump operation is therefore with minimal wear, vibrations free and noise levels are greatly reduced.
