Liquid ring vacuum technology

Managing noise from vacuum trucks is essential for protecting operators’ health and eliminating noise pollution. Keeping exposure at 70 dB(A) or lower is recommended. Every 3 dB(A) increase doubles the noise level, intensifying the impact on health and well-being. Strict guidelines from organizations such as WHO, ILO, OSHA, and the EU require fleet operators to address workplace noise. At a distance of 7 meters, blowers produce a noise level of 78 dB(A), vane pumps emit 74 dB(A), while liquid ring pumps are the quietest at just 64 dB(A). Choosing liquid ring technology is the most effective way to protect operator health, ensure regulatory compliance, and minimize noise pollution.

Liquid ring pumps operate with low levels of vibration, reducing the risk of premature wear on vacuum trucks and reducing operator discomfort. Lower vibration levels can help prevent health issues such as headaches, fatigue, joint pain, and long-term musculoskeletal problems, resulting in smoother operations and improved well-being for operators.

Liquid ring vacuum pumps are exceptionally well-suited for vacuuming all kinds of materials including slurries, mud, and contaminated substances, provided the right pump and truck design are used. This versatility makes them the top choice for vacuum trucks in municipal, industrial, and environmental cleanup operations.

Contrary to common misconceptions, liquid ring technology is fully capable of achieving deep vacuum levels, down to 33 mbar absolute or even lower. This performance not only meets but often exceeds the requirements of most vacuum truck applications.

Liquid ring pumps are highly resistant to damage from debris, wet or humid air, vapors, and liquids that may enter the pump. Unlike vane pumps and blowers, which can be damaged by such materials, liquid ring pumps offer greater reliability and durability in harsh conditions, helping to minimize maintenance and repair costs for vacuum trucks.
