Travaini – TCD

TCD pump series (see cross section below) are specifically designed to handle thermal fluids up to 320˚C without special cooling systems. The heat from the pumped product is greatly blocked by special “heat barrier” chamber located between the pump casing and the impeller. The bearing frame has been especially designed with cooling fins to effectively dissipate the heat coming from the pump casing so that standard, simple and single mechanical seal can be safely used. The rotor is supported with oversized ball bearings of the C3 series that are lubricated with oil of medium viscosity. Pump casings and impellers are the same as for pump series TCH smaller two frames. Materials of construction are Ductile iron or Stainless steel AISI 316. For the latter construction it is possible to have a special seal arrangement “SP” (see page at side). Pump dimensions and characteristics are in accordance to ISO 2858/DIN 24256 standards and are the same as for the correspondent models from the TCH series. Capacity up to 350 m3 /h and head to 10 bar.

Features

Max. Capacity: to 350m3/h
Max. Pressure: to 10 bar

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.

Mechanical Seal

TCH pump series and derived series can be fitted with any type of mechanical seal that is unified to the ISO 3069/UNI EN 12756 standards. Single mechanical seals, double mechanical seals in tandem or back to back arrangements can be fitted with flushing systems to API standards. The pump bearing frame offers versatility and plenty of space to also allow fitting special types of mechanical seals that may not have unified dimensions, i.e.: cartridge type seals

Materials

TCH pumps have many material solutions, starting from cast iron and stainless steel iron up to SAF and Hastelloy.
