TCH – Centrifugal single stage pumps

The new Travaini centrifugal single stage pumps of the TCH series and derived series of the same family, reflect the design guidelines given by ISO 5199 class II standards: these norms provide for the introduction of new and severe manufacturing standards applicable to the pumps manufactured according to ISO 2858/DIN 24256 standards in order to get an ideal product for the heaviest uses, especially in the petrochemical industry, following the example of API standards.

The new Travaini centrifugal single stage pumps of the TCH series are also the results of continuous research and development, of the extensive experience acquired over many years with the previous series MCU-CH applied in numerous installations and fields.

The new Travaini centrifugal single stage pump of the TCH series is an extremely improved product which guarantees:

  • Toughness
  • Efficiency
  • Reliability
  • Safety
  • Durability
  • Lower operating costs

The manufacturing program includes three bearing frame sizes of the “Back pull-out” type, the pump casing is of the spiral type with axial suction flange, the impeller is of the radial type with overhang mounting. All our production is guaranteed by certified quality system according to ISO 9001:2000 standards.

  • Technical specifications according to standards ISO 5199
  • Overall dimensions and performances are in accordance to standards ISO 2858/DIN 24256.

APPLICATIONS

Handling clean or slightly contaminated liquids, hot, superheated, acidic and caustic in chemical industry, petrochemical, pharmaceutical, food, pulp and paper, environmental, steel, textile, etc.
