  • Responsibility for the environment
  • By its absolute tightness to the atmosphere Canned Motor Pumps fulfill the highest requirements in respect to environmental- and immission protection. The complete production line of HERMETIC-Pumpen GmbH is an essential contribution in observing the EC directive 96/61/EC, the so-called IPPC directive (Integrated Pollution Prevention and Control) and the Federal Immission Protection Law and TA-Luft respectively.
  • Seal-less canned motor pumps, are considered as being the “Best Available Technology” acc. to the IPPC directive and its data sheets for conveying fluids, which are dangerous and harmful to the environment.
  • Innovation and experience for your product
  • We are one of the world’s leading manufacturers of seal-less centrifugal pumps. The products of the company HERMETIC-Pumpen GmbH stand for best quality and highest operational safety in the chemical and petrochemical industry, as well as in refrigeration and nuclear industry.
  • We combine materials of high quality and individual solutions to sophisticated products.
  • Our products being at the highest safety level feature a great development in partnership with our customers, exceptionally long service lives of our pumps and low life-cycle costs. Canned motor pumps offer great advantages in the fi eld of operation, maintenance and performance.
  • Technology at the highest stage
  • One critical item when using conventional centrifugal pumps is to seal the shaft passages on the pump casing. Besides the high rate of repairs, this is a reason for the steadily increasing use of seal-less pumps. The praxis shows that seal-less pumps generally have less repairs than in comparison with conventional chemical pumps with mechanical seal and consequently, they feature a longer service life.
  • The refrigeration and cooling industry has also used canned motor pumps for a long time without any problems. Thus, besides the absolute tightness and high safety of these pumps, they additionally offer both, the advantage of minimized maintenance and high availability.
  • For your safety – always being one step ahead
  • We offer a highest level of safety – also with extreme parameters:
  • - High potential risk originating from the medium to be conveyed
  • Fluids to be conveyed at extreme temperatures- High-pressure circulation
  • - Explosion protection
  • HERMETIC – Our name stands for our product line
  • „Nomen est Omen“.
  • The name HERMETIC relates to „Hermes Trismegistos“ the famous magician of Greek mythology, who could seal treasures and pots, that means make it „hermetically „ tight.
  • HERMETIC stands as synonym for absolute tight and leakage free delivery.

  • Balancing of the axial thrust is an important factor of the final testing.
  • Improper axial thrust balancing is the primary pump failure.
  • Axial thrust balance is influenced by the plant itself or by pumped liquid.
  • For early failure detection, rotor position monitoring is recommended.
  • By separate monitoring of the bearing clearance and the direction of rotation, several models of pump failure can be detected.

For example: ARM-2000 AM-2000
