Product Description
Pompetravaini TMA Multistage Centrifugal Pumps
The Pompetravaini TMA Multistage Centrifugal Pumps are horizontal, high-pressure pumps designed for clean-liquid industrial duties. Their closed impellers are mounted in series; therefore, the liquid gains additional pressure as it passes through each pumping stage.
The TMA range covers capacities from 1 to 45 m³/h and discharge heads from 4 to 40 bar. Consequently, the pumps suit systems that require moderate flow combined with high pressure.
TMA High-Pressure Centrifugal Pump Design
Each closed impeller contributes additional head while maintaining the required capacity. As a result, the Travaini TMA multistage pump can develop considerably higher pressure than a typical single-stage centrifugal pump.
However, the TMA is not identified as a self-priming pump. Therefore, users must provide suitable priming, flooded suction or another approved inlet arrangement before operation.
Key Features of Pompetravaini TMA Pumps
- Horizontal multistage centrifugal construction
- Closed impellers installed in series
- Capacity range from 1 to 45 m³/h
- Head range from 4 to 40 bar
- Balanced axial-thrust arrangement
- Heavy-duty ball-bearing support
- Robust one-piece component design
- Reduced pump weight without sacrificing strength
- High-pressure clean-liquid capability
- Multiple model and stage combinations
- Close-coupled options for smaller TMA 31 and TMA 32 pumps
- Compact installation options
- Suitable for medium- and high-pressure duties
Together, these features allow the Pompetravaini TMA Multistage Centrifugal Pumps to support pressure boosting, circulation and process-transfer systems.
Closed-Impeller Multistage Pump Operation
The TMA pump uses multiple closed impellers rather than one large hydraulic stage. Therefore, each stage progressively increases the liquid pressure.
Moreover, this arrangement allows engineers to select the required number of stages according to the system head. Consequently, the pump can be matched more accurately to the required operating point.
Balanced Axial-Thrust TMA Pump Design
Pompetravaini uses balancing blades on the rear of the impellers to control axial thrust. Meanwhile, the remaining forces are absorbed by a heavy-duty single ball bearing at the non-drive end and angular bearings at the drive end.
As a result, the rotating assembly receives stable support during high-pressure operation. Moreover, controlled thrust can help protect bearings, seals and other rotating components.
Robust Pompetravaini Multistage Pump Construction
The TMA design uses modern foundry methods that allow principal components to be produced as strong one-piece parts.
Consequently, the construction can improve hydraulic efficiency while reducing unnecessary weight. In addition, fewer complex component interfaces can simplify assembly without compromising overall durability.
TMA Seal-Pressure Management
Selected TMA configurations use two external bearing supports. In these designs, a pressure pipe relieves pressure around the discharge-side seal area by connecting it towards the suction side.
Therefore, the arrangement helps manage pressure around the shaft-sealing system. However, the exact seal arrangement and construction must be confirmed for the selected model and liquid.
Close-Coupled TMA 31 and TMA 32 Pumps
Smaller TMA 31 and TMA 32 models are available in a close-coupled design where installation space is limited.
Moreover, close coupling removes a separate pump-to-motor coupling alignment requirement. As a result, the arrangement can reduce overall dimensions while helping maintain reliable alignment and performance.
TMA Multistage Pump Performance Range
The complete series provides:
- Minimum published capacity: Approximately 1 m³/h
- Maximum published capacity: Approximately 45 m³/h
- Minimum published head: Approximately 4 bar
- Maximum published head: Approximately 40 bar
However, these values represent the complete range. Therefore, users should not apply 45 m³/h and 40 bar simultaneously to every TMA model. The final operating point depends on pump size, number of stages, speed and selected configuration.
UAE Applications for Travaini TMA Pumps
The Pompetravaini TMA Multistage Centrifugal Pumps are designed for clean-liquid, medium- and high-pressure services. Therefore, suitable configurations may support:
- Industrial water circulation
- Pressure-boosting systems
- Clean process-water transfer
- Boiler-feed support systems
- Condensate transfer
- Reverse-osmosis feed systems
- Cooling and heating circuits
- Wash-water systems
- High-pressure equipment supply
- Compatible clean chemical transfer
These applications are practical inferences from the official clean-liquid, high-pressure operating range. However, chemical transfer requires confirmed construction and seal compatibility.
Selecting Pompetravaini TMA Multistage Centrifugal Pumps
Correct selection depends on:
- Required capacity
- Total discharge head
- Liquid composition
- Operating temperature
- Specific gravity and viscosity
- Available inlet pressure
- Required number of stages
- Shaft-seal arrangement
- Construction materials
- Motor speed and power
- Installation layout
Therefore, the Pompetravaini TMA Multistage Centrifugal Pumps should be selected from the model-specific performance curve. Otherwise, an incorrect operating point may cause cavitation, excessive power consumption or reduced service life.
