TRVX series: More efficient vacuum systems with lower energy consumption and easier maintenance
By Morgan Malm
Energy-efficient vacuum systems are becoming increasingly important for businesses looking to reduce energy consumption, increase reliability and simplify installation. The TRVX series, developed by our partner Pompetravaini, offers a modern and practical solution to meet these needs.
The TRVX series is based on long experience and development work. The result is a liquid ring vacuum pump with high efficiency, reliable operation and a well thought-out design that simplifies daily work without complicating the technology.
Energy-efficient vacuum systems for thehigher energy consumption and more stable operation
Many customers raise the same challenges: high energy costs, limited space, plumbing systems that have grown too complex and service that takes unnecessary time. It is precisely these elements TRVX series is designed to simplify.
With a new hydraulic design, the pump delivers over 10 percent higher efficiency compared to traditional liquid ring pumps. This means:
- lower energy consumption
- more stable operation over time
- reduced operating costs
In facilities where the vacuum system is running most of the day, the difference becomes clear quickly. Energy-efficient vacuum systems provide both quieter operation and better control of energy costs, which is reflected in both performance and economy.

Compact and easy installation without compromising on capacity
In addition to improved performance TRVX series developed with a focus on practical handling. The pump is on average 30% lighter and up to 50% more compact than previous generations. Which brings many clear advantages:
- faster installation
- easier placement, even in tight spaces
- lower installation costs
For many sites, this means that the pump can be integrated without extensive customization.
Sophisticated design simplifies installation, service and long-term operation
The TRVX series is built to reduce complexity in both installation and maintenance. With one inlet and outlet, piping is reduced, installation is faster and service access is easier. The integrated suction and discharge channels also reduce the number of separate components, resulting in shorter service interventions and less downtime.
To ensure high reliability over time, the inlet and outlet plates are made of stainless steel as standard, providing good resistance to wear and corrosion. The plates are also reversible, which extends their lifetime and contributes to lower spare parts costs.
Reliability that lasts over time
Sustainability is a key part of Pompetravaini's development work. That's why the inlet and outlet plates are made of stainless steel as standard. It provides:
- higher resistance to wear and corrosion
- stable performance over a long time
- less need to replace spare parts
The plates are also reversible, which means that the same component can be used for longer. This reduces spare parts costs and makes it easier to plan maintenance without surprises.
A modern and reliable solution for the future of vacuum systems
Many of our customers have chosen the TRVX series, which combines high efficiency, compact design and easy serviceability. The pumps are supplied as individual units or as part of a complete vacuum system from Pometravaini.
The result is a vacuum system that is more stable, more energy efficient and easier to work with in everyday life.
Whether you are upgrading an existing facility or planning a new installation, the TRVX range is a strong option for safe and cost-effective operation.

What is a liquid ring vacuum pump and when is it used?
A liquid ring vacuum pump is a robust type of pump that creates vacuum using a rotating liquid ring. It is widely used in process industry, food, chemical handling and other applications where stable operation, durability and low service requirements are important.
How to reduce energy consumption in a vacuum system?
Energy consumption can be reduced by choosing a pump with high efficiency, optimizing piping, avoiding unnecessary capacity and ensuring that the system is properly sized. Newer pumps often have modern hydraulic designs that reduce energy use compared to older models.
What to consider when installing a vacuum system?
Important factors are available space, piping, vibration levels, ease of access for servicing and whether the installation requires additional cooling or water flow. A compact pump with fewer pipe connections can simplify installation and reduce costs.
How to simplify the service and maintenance of vacuum pumps?
Servicing is easier if the pump has good access to wear parts, integrated channels and a design with few separate components. Material choices such as stainless steel also make wear parts last longer, reducing downtime and spare part costs.
How do you know when it's time to upgrade your vacuum system?
Signs that a vacuum system should be replaced are increasing energy costs, frequent downtime, inaccessible service, high noise levels or if the installation is no longer optimized for today's requirements. Newer systems often offer both better efficiency and lower overall operating costs.
