TCT

TCT SERIE

Monostage centrifugal pumps

TCT pump series are capable of handling without clogging liquids with suspended solids or filaments, as well as muddy and viscous liquids.

The impeller is of the internal vortex type. The liquid is handled by means of the vortex motion created by the impeller that do not come in direct contact with

the pumped liquid.

The construction utilises the pump casing, casing cover and bearing frame from the series TCH and derived series. The highly efficient characteristics are

therefore retained, with the added bonus of reduced number of spare parts to be stocked.

Dimensions are unified to ISO 2858/DIN 24256 except for the overall length that is greater.

Capacity up to 250 m3/h and heads to 7 bar.

TCA SERIE

Monostage centrifugal pumps

TCA pump series are primarily designed to handle highly abrasive liquids and having suspended solids.

The impeller is of the open type, rotating between two wear plates, front and back. The four blades special hydraulic profile offers high hydraulic efficiencies

and low NPSH requirements.

The construction utilises the pump casing, casing cover and bearing frame from the series TCH and derived series. The highly efficient characteristics are

therefore retained, with the added bonus of reduced number of spare parts to be stocked.

Dimensions are unified to ISO 2858/DIN 24256 and are identical to those of pump series TCH.

Capacity up to 100 m3/h and heads to 10 bar.

TCD SERIE

Monostage centrifugal pumps

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”

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.

TCD /SP

SPECIAL CONSTRUCTION

TCD/SP pump series has been especially designed to handle

vegetable oils. The design varies from the standard TCD series only in the mechanical seal

area; an intermediate cover has been added beyond the mechanical seal. This intermediate

cover should be connected to a reservoir containing oil compatible with the pumped fluid.

This device avoids that, in case of mechanical seal breakdown, air can enter into the pump

irreparably oxidating the pumped oil or that oil of bearings enter into pumping circuit or vice

versa.

TCHV - TCTV – TCAV

Monostage centrifugal vertical pumps    (derived from horizontal pump series)

TCH, TCT, TCA pump series are available for vertical installation with lateral discharge flange.

The main design features are:

• Lengths are from approximately 500 mm to 3000 mm

with or without intermediate support sleeve.

• Available materials of constructions are same as for the

horizontal mounted pumps.

• Depending upon the applications the sleeve bearings can

be carbon, bronze or impregnated Teflon materials.

• Pump casing, impeller and casing cover are the same as

for the series TCH, TCT, TCA.

• The standard rectangular base can be modified to

accommodate specific requirements.

• Standard shaft sealing is by radial seal rings. Packed

stuffing box or mechanical seal shaft sealing are available

upon request.

• Lantern for monoblock design is available for B5 or V1

motors up to 110 kW.

• Internal sleeve bearing flushing is standard but provision

for flushing from an outside source is provided.

• Filter screen can be fitted at suction side upon request.
