Tank Truck Emptying in the Chemical Industry

The TORNADO® T.Proc® in all-metal design empties without interruption 

Przemysł chemiczny ułatwia nam codzienne funkcjonowanie w różnych dziedzinach życia. Bez chemii nie byłoby niezliczonych produktów codziennego użytku. Nie byłoby samochodów, komputerów, środków czyszczących czy też protez zębowych.
W przemyśle chemicznym jest szereg zastosowań, które wymagają tłoczenia różnych produktów, takich jak na przykład zmiękczacze, kleje, mocznik, zawiesiny, nadtlenki wodoru, kaolin, PCW, PAW, żywica czy dwutlenek tytanu. Pompy NETZSCH® to idealny partner. Tylko dla samego przemysłu chemicznego firma NETZSCH wyprodukowała w ostatnich pięciu dziesięcioleciach ponad 150 000 pomp.
Tradycyjne materiały takie jak stal szlachetna czy żeliwo szare w szczególności w przemyśle chemicznych nie zawsze są odpowiednie. Z tego powodu NETZSCH oferuje również POMPY NEMO® wykonane ze stali duplex, Hastelloy®, Uranus® lub tytanu. Prosimy o kontakt. Zespół ekspertów NETZSCH dobierze wspólnie z Państwem właściwe rozwiązanie do danego przypadku zastosowania.

Tank Truck Emptying in the Chemical Industry With TORNADO® T.Proc® Rotary Lobe Pump

Look behind the scenes

The difficulties involved are air pockets which cannot be avoided when attaching a pipe. The gas bubbles initially lead to reduced performance and irregular running until the product flow stalls as the gas inflow further increases.

Challenge accepted

The product flow used to stall again and again during the emptying of the surfactant with the centrifugal pump that was used before. The centrifugal pump was intended to convey the basic material of the detergent from a road tanker to the company's production facility. However, problems arose as early as the suction phase: air which got into the pipe during connection of the tank formed air pockets in the medium. This led to slumps in performance and also to repeated stalling of the product flow. The pump kept on breaking down and had to be recommissioned, involving a great deal of effort from the personnel. Tanker drivers were often obliged to suffer a long unscheduled wait until the tank was empty, which meant high additional costs for hazardous goods carriers who have to adhere strictly to driving and rest times.


cP viscosity are no problem

Excellently solved

The surfactant being conveyed was diluted with a solvent in this application. Most plastics are not resistant to solvents and elastomer swells in contact with them and impairs pump performance. For this reason, the all-metal model of the x made of stainless steel was installed. This type of TORNADO® rotary lobe pump enables to guarantee a long service life for all parts that come into contact with the product. A special universally usable elastomer was used for the seals which has high chemical and temperature resistance due to its composition. As the pump operates in an area which is designated as an explosion protection area 1, the pump must not run dry under any circumstances. For this reason, both pressure and dry running protection were integrated so that the pump automatically switches off in the event of a fault. The positive displacement pump has now been running trouble-free since the end of October 2013 and conveying 15 to 20 m³ of surfactant per hour at a pressure of four bar.

Meanwhile, there is no longer need for supervisory staff during the emptying of the tanker thanks to this high level of reliability and drivers can easily start the process themselves and complete it within the scheduled time frame. Additional costs for waiting times, production downtimes and the staff effort involved in recommissioning the centrifugal pump are a thing of the past.
