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.


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

  • Overall dimensions and performances are in accordance to standards ISO 2858/DIN 24256.
  • Materials of construction are numerous, from cast iron to hastelloys.
  • High hydraulic efficiencies and low NPSH requirements.
  • Shaft sealing by packed stuffing box, single or double mechanical seals (ISO 3069/UNI EN 12756) with every installation option per API requirements.
  • Pump casing and seal housing can be provided with heating or cooling chambers, as needed.
  • Units up to 30 kW size can be close coupled, with the addition of a support lantern, to motors with B5 flange. This monoblock design offers great alignment advantages, simplicity of assembly and guarantee of perfect alignment even after transportation.
  • From the TCH series have derived series TCT, TCA and TCD that are designed for very specific pumping applications; all these series utilise many common components.
