FATTY ACIDS

Do you Want to Pump Fatty Acids Safely and Directly From Tank Trucks?

With this pump, you protect the health of your employees in the long term

Depending on their chemical composition, fatty acids can attack the skin or even the respiratory tract in case of unprotected contact and thus cause damage to health. For this reason, there are strict legal requirements for fatty acid pumps. An old gear pump could no longer meet these requirements , thus presenting a paint and varnish manufacturer with significant problems.

NETZSCH Pumps & Systems, the global specialist in complex fluid management, offers you innovative solutions, including for pumping chemicals. We show you how to pump fatty acids directly from tank trucks, protecting your employees’ health.

Challenges when pumping fatty acids directly from tankers

Every commercial and industrial company in Europe today is subject to various regulations for protecting personnel, consumers and the environment. These concern not only the manufacturing machines themselves but also the pump systems used. Especially the cosmetics and the paint and varnish industries use fatty acids in their production processes. Depending on their chemical composition, concentration and volatility, the acids can burn the skin or respiratory tract in case of unprotected contact. Therefore, fatty acids fall within the Technical Instructions on Air Quality Control (TA Luft; Technische Anleitung zur Reinhaltung der Luft. These contain emission and immission limits for exhaust gases, all kinds of hazardous substances, and environmental pollution. They regulate that fatty acids must not come into contact with the atmosphere. Therefore, they must be pumped directly from tank trucks. Another challenge involved in pumping fatty acids is their viscosity. Due to the high viscosity of fatty acids, it can be difficult to pump them through the pipeline, especially when they become solid at lower temperatures. In addition, fatty acids can corrode metal and other materials and are sometimes abrasive. The pump and piping must be made of corrosion-resistant materials and be resistant to wear in order to avoid damage and associated costs.

Gear pumps are not suitable for pumping fatty acids

For a long time, a manufacturer of paint and varnish used a gear pump to feed its tank trucks with fatty acids. However, the existing gear pump could no longer meet the strict legal requirements for protecting personnel, consumers and the environment. In order to prevent exposing its employees to any risks, the company approached the global specialist for complex fluid management NETZSCH with its requirements. The sticky and temperature-sensitive medium must be pumped at 70°C to remain flowable. At the same time, the installation area for the pump is declared as an explosion zone one due to possible gas accumulation, therefore the pump must be ATEX-compliant. In addition, the fatty acids to be pumped have an abrasive effect, which leads to high wear on the gear pump. Together with the company, the experts from NETZSCH found the optimal pump solution for safely pumping the fatty acids directly from the tank wagons.

The compact TORNADO® T.Envi® rotary lobe pumps impress with easy maintenance thanks to the innovative FSIP® (Full Service in Place) design. 

How to pump fatty acids in compliance with the strictest legal requirements

After thoroughly analysing the requirements, the global specialist in complex fluid management recommended using a TORNADO® T.Proc®rotary lobe pump. The T.Proc® offers three decisive advantages: Safety, FSIP® (Full Service in Place) design and insensitivity to dry running. Specially designed for particularly challenging media, the rotary lobe pump from NETZSCH allows you to pump with maximum operational safety. Thanks to the worldwide unique spatial separation of the pump and gear chamber, maximum operating safety is always ensured. In this way, you prevent contamination of the pumped medium. In addition, the T.Proc® meets the strict requirements of the TA Luft. With the TORNADO® T.Proc® rotary lobe pump, you not only prevent contamination of the medium but also ensure the protection of personnel, consumers and the environment. Another advantage offered by the rotary lobe pump is the innovative FSIP® design. It makes maintenance particularly easy without having to remove the pump from the pipeline first. This significantly reduces your service time and costs.

The rotary lobe pump is also insensitive to dry running and therefore ATEX compliant. This means that nothing stands in the way of pumping fatty acids in compliance with all regulations. Due to the aggressive medium and the high pumping temperatures, an all-metal design was chosen. The high-strength steel used is highly resistant. This offers you a long service life. In addition, this material allows production with tiny gaps between the lobe rotor and the housing, which results in a high degree of efficiency for you. At the production site of the manufacturer of paint and varnish, the pump has been reliably performing its duties for several years and fills the manufacturer's tank trucks with 20 m³/h at a pressure of 2.5 bar. Replace your old gear pump with an innovative pump solution from NETZSCH and protect your employees and the environment from damage.
