Centrifugal pumpsTCH series - Chemical norm centrifugal pumps ISO 2858
Pompetravaini's new TCH series and derived series in the same family is a centrifugal pump developed according to ISO 5199 class II and dimensioned according to ISO 2858/DIN 24256. It provides an ideal product with great width and modularity adapted to the high requirements of the process, petrochemical and chemical industries in particular. These pumps are the result of Pompetravaini's continuous research and development. They are also based on the extensive experience acquired during many years of use of the previous MCU-CH series in countless installations and applications. Shaft seals single or double mechanical seal (ISO 3069 / UNI EN 12756) Cartridge seal and stuffing box seal in various designs. Pump and seal housings can be fitted with heating or cooling jackets as required. Handling of clean or slightly contaminated liquids, hot, acidic and caustic chemicals is important in several industries. This includes the chemical, petrochemical, pharmaceutical, food production, pulp and paper, steel and textile industries. From the TCH series are derived the TCT series - Vortex pumps, the TCA series - open impeller and the TCD series - Thermal oil pump; all designed for very specific pumping applications. All these series use several common components. Units up to 30 kW can be close coupled, with the addition of a lantern piece to B5 flange motors. This monoblock design provides alignment advantages, easy assembly and guarantee of perfect alignment, even after transportation.Pompetravaini -

Centrifugal pumpsTCD series - Chemical norm centrifugal pumps for high temperatures ISO 2858
TCD centrifugal pump for thermal oil. The TCD pump series is specially designed to handle thermal fluids up to 320˚C without special cooling systems. In the active cooling version "XT" it is possible to pump diathermic fluids up to a temperature of 365 °C. A special thermal barrier chamber, located between the pump casing and the impeller, blocks the heat from the pumped product. The designers have designed the bearing with cooling fins to effectively dissipate the heat from the pump casing. This design allows the safe use of a standard, simple mechanical seal. The pump shaft is supported by oversized C3 series ball bearings and is oil lubricated. The pump casing and impeller are the same as the other pumps in the two smallest models of the TCH series. Pump dimensions and characteristics are in accordance with ISO 2858/DIN 24256 and are the same as for the corresponding TCH series models. The TCD/SP pump range has been specifically designed to handle vegetable oils. The design varies from the standard TCD series at the mechanical seal; An additional chamber has been added behind the mechanical seal. This chamber should be connected to a container containing oil compatible with the pumped liquid. This device avoids that in case of seal failure, the air can enter the pump and oxidize the oil or that oil from the bearing housing enters the pump housing or vice versa.Pompetravaini -
Centrifugal pumpsTCHM/TCTM series - Chemical norm centrifugal pumps in compact design ISO 2858
TCHM and TCTM series of Pompetravaini are of the highest quality with high efficiency and attractive price to chemical industry and industry in general.

What is a centrifugal pump?
A centrifugal pump is a rotary pump that uses an impeller to convert mechanical energy into pressure energy. The impeller sets the fluid in motion and, with the help of centrifugal force, creates a smooth and stable flow in the system.
Thanks to their simple design, high reliability and ability to handle both clean and slightly contaminated liquids, centrifugal pumps play an important role in many industrial processes. You can find them in a variety of designs - tailored to specific applications and industries.
Advantages of centrifugal pumps in industry
Centrifugal pumps work well in industrial environments thanks to their reliability, high capacity and minimal maintenance requirements. Here are some of their main advantages:
- Simple design - Few moving parts minimize the risk of breakdowns and make maintenance easy.
- Cost-effective operation - The combination of low purchase cost and energy efficiency reduces operating costs.
- High capacity - Handles large volumes of liquid without losing performance.
- Flexible use - Handles different fluid types, temperature ranges and hygiene requirements with ease.
- Optimal for continuous operation - Delivers a smooth and stable flow for long periods of time.
