Chemical Hermetic Disk Pumps GHD series

 Chemical Hermetic Disk Pumps GHD series

Chemical Hermetic Disk Pumps GHD series

Features and applications:

  • used to pump high-viscous (to 10000 cSt), aggressive, highly inflammable and toxic media, as well as oil products containing solids and fibers, in hazardous areas;
  • hermeticity is guaranteed due to face seals and a stationary separating shield;
  • torque transfer via SmCo and NdFeB magnets;
  • liquid end made of stainless steels and alloys;
  • volume content of solids (up to 2 mm) and fibers in the pumped medium up to 15%;
  • working temperature from -40°C to +150°C;
  • comply with TDFA.062815.000TU;
  • first hermetic disk pumps produced in Russia;
  • licensed by the Federal Service for Ecological, Technological and Atomic Supervision.

Innovative features and original designs have been patented by Hydrogas.

Chemical Hermetic Disk Pumps GHD series

Material of liquid end:

  • alloys;
  • stainless steels.

In the pump the discharge pressure is created by a working mechanism consisting of two disks, which move the product using the forces of viscous resistance. This pupms have major advantages over centrifugal pumps when handling high viscous, inhomogenious and abrasive media.
The use of hybrid seals helps to eliminate leakages of highly aggressive and viscous (up to 10000 cSt) media containing solids and fibres.

Hermetic disk pumps can now handle the following media:

  • viscous oil products, such as pitches, tars, asphalt;
  • chemical products with a high content of suspensions: pulp, emulsions, etc;
  • mixtures in paper and tobacco industries;
  • liquid polymers, gels, greases, syrups, etc.
