Sustainable operations

Our climate is under more pressure than ever before, and global warming of 1.5°C and 2°C will be exceeded unless we succeed in drastically reducing CO₂ and other greenhouse gas emissions in the coming decade. With new legislations, regulations and societal demands, governments and countries around the world are raising their climate ambitions. This is pushing companies and municipalities into assessing their operations and actively working to build more sustainable equipments.

By 2050, two thirds of the worldʼs population are projected to live in urban areas and have an increased expectancy for living standards and a desire to have access to more effective sewage systems and clean water. This calls for more sustainable and resilient cities. The infrastructure of cities is a vital part of ensuring more sustainable and comfortable living. To provide maximum comfort to citizens, sewage systems must be maintained by vacuum trucks that not only can operate silently and efficiently but that they are also sustainable. Make the switch to more sustainable operations. Make the switch to liquid ring technology. The only sustainable vacuum pump technology for your vacuum truck.

Zero oil emissions I Just clear exhaust

Vane pumps are oil-lubricated vacuum pumps that emit oil mists, posing risks to the environment and to people nearby.

On the other hand, the liquid ring vacuum pump creates its suction power on water and emits no oil. This, very clean type of operation, makes the liquid ring pump the suitable choice for urban applications and protection of operators’ health.

The capacity of the liquid ring pump to discharge just clear exhaust is particularly crucial in industries where preventing contamination and pollution is paramount.

No noise pollution

Blowers, while effective, are known for their high noise pollution, emitting a noise level of 95 dB(A) at 1 meter distance, comparable to the deafening sound of a subway train. At a distance of 7 meters, blowers still produce 78 dB(A), similar to the noise of a crowded city street during rush hour.

The liquid ring pump, on the other hand, emits a noise level of 81 dB(A) at 1-meter distance, like the noise inside a passenger car. And at a distance of 7 meters, the liquid ring pump emits a sound of 63 dB(A) similar to that of a children’s playground. Considering its significantly lower noise output at both proximities, the liquid ring pump is approved as the technology that prevents noise pollution.

Safer for the operator and passersby

When safety is a top priority, liquid ring pumps stand out as the superior choice over vane pumps and blowers. The liquid ring pumps contribute to more sustainable operations by having a clean exhaust, protecting the operators and passersby. They have a low noise level while in operation, preventing noise pollution. And there is no risk of explosion, contributing to a safer work environment.

Longer lifecycle

The robust design of liquid ring pumps contributes to their long lifespan. With fewer moving parts and no friction, liquid ring pumps have a longer lifespan when compared to vane pumps and blowers. Not only do they have a longer lifespan, but they also require less maintenance. This results in fewer replacement parts and lubricants, and lowers the overall energy and material consumption over the pump’s lifecycle. And the built-in strength and robust design translates into a reduced manufacturing footprint.

No risks for explosions

The absence of sparking risk in liquid ring pumps contributes to their sustainability by enhancing safety and reducing the risk of hazardous situations.

Since liquid ring pumps do not have metal-to-metal contact within their operating mechanisms, the likelihood of sparks, which could ignite in certain industrial environments, is eliminated. This makes them particularly valuable in industries where explosive or flammable vapors are present, preventing accidents and damage to the environment.

Only water is used

The liquid ring pump uses only water. Advances in the technology made it possible to recirculate the service liquid, significantly reducing water usage. Other vacuum pumps use as lubricants oil or other greases. These types of lubricants are not only costly but they are harmful for the nature and cannot be reused.
