APPLICATIONS FIELDS

TCH SERIES

ISO 2858 version : dimensions and performance standards

Closed impeller

design suitable to

handle clean liquids

1X ISO 5199 version (optional) : technical specifications

TCH … 1X… VERSION

• Oversized shaft

minimizes deflection (<50

microns) and vibrations

thus improving the mech.

seal life

• High bearing span with

an optimal value L3/D4

• Oversized bearing to

handle both radial and

axial loads with a life

expectancy over 25000

hours of operation

*L

D shaft diameter (NOT sleeve)

L overhung length

TCH …. /1X-C/A3-M/T

“T” stands for mech. seal housing

fitted with cooling or heating

chamber.

Cooling, in case of hot liquids, is

required to avoid an increase of the

stuffing box temperature due to the

mech. seal sliding faces friction.

Heating is required when handling

some waxy products that may

solidify at ambient temperature.

“T” is optional

TCH …. /1X-C/A3-M/U2 or U0

“U2” and “U0” stand for casing

jacketed for heating or cooling.

TCH pumps in U2 or U0 version

are always made of AISI 316

material of construction.

Heating, carried out by mean of

thermal oil or steam, it is required

in case of waxy products that may

solidify at ambient temperatures.

“U2” version always includes “T”.

“U0” version is without “T”.

TCT SERIES

Vortex impeller

design capable of

handling without

clogging liquids

with suspended

solids or filaments

(in limited %), as

well as muddy and

viscous liquids.

Dimensions unified to ISO 2858/DIN 24256 (except for

the pump overall length which is more extended)

“1X” ISO 5199 available

TCA SERIES

Open impeller

design for

handling abrasive

liquids (such as

vegetable oils

with bleaching

earths). The

impeller is

mounted between

two plates which

are the only parts

subjected to wear.

Dimensions unified to ISO 2858/DIN 24256

“1X” ISO 5199 available

TCD SERIES

Dimensions and characteristics in

accordance to ISO 2858/DIN 24256

Close impeller

design suitable for

handling thermal

fluids (mainly

diathermic oil) up

to 320°C. Cooling

fins help to

dissipate the heat

coming from the

casing without

special cooling

systems.

Temperature dumping by means of cooling

fins

The heat from the pumped

product is greatly blocked by

special “heat barrier” chamber

(VDMA 167) 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

mech. seal can be safely used.

TCD SP version

“SP” is a specific version only

available in AISI 316 material of

construction

TCD/SP has been

especially designed to

handle vegetable oils.

An intermediate cover

(VDMA 184) has been

added beyond the mech.

seal, to be connected

with a reservoir

containing compatible

oil. In case of mech. seal

breakdown this avoids

that air enters into the

pump oxidizing the

pumped medium or that

bearing oil pollutes the

pumped medium.

Compatible oil flushing

cover (VDMA 184)

Materials of construction

GS, RA and A3 versions are standard materials of construction

For pumps series TCT and TCA the impeller material of

construction is always AISI 316 (and so is for the GS version).

Pressure and temperature limitations

Limitations valid

for A3, HC, DU.

For GS and RA

the lowest limit

is -20°C.

These values are valid for temperatures of pumped liquids,

not for ambient temperatures. In case of overheated liquids

(such as overheated water) those limits are no longer valid.

In case of high temperatures also the mech. seal and the

sealing system have to be carefully evaluated.
