Frequently asked questions
Do you have a pump similar to the Pompetravaini TRX 1257/1W-C/SX?
Yes. Rezitech offers the 2BE1 Liquid Ring Vacuum Pump range as a suitable alternative for many applications where a Pompetravaini TRX series pump is used. The 2BE1 series is designed for industrial vacuum duties involving vapour, air, and wet gas handling across mining, chemical, petrochemical, mineral processing, and manufacturing industries.
The Rezitech 2BE1 range provides:
- Vacuum capability down to approximately 33 mbar abs.
- Capacities from approximately 250 m³/hr up to 26,000 m³/hr
- Low vibration and low noise operation
- Robust liquid ring design suitable for harsh industrial environments
- Material options including ductile cast iron and stainless steel
- Direct replacement compatibility with many Siemens/NASH-style 2BE series pumps
Because the Pompetravaini TRX 1257/1W-C/SX model may have specific performance requirements such as flow rate, vacuum level, seal arrangement, materials, and motor configuration, Rezitech recommends confirming:
- Required vacuum level
- Flow capacity
- Gas composition
- Operating temperature
- Materials compatibility
- Existing installation details
This allows the team to recommend the closest equivalent model within the 2BE1 range.
