How to Pump Abrasive Industrial Wastewater With Low Wear and Tear

TORNADO® T.Envi® rotary lobe pump facilitates industrial wastewater treatment

Global warming is causing water to become increasingly scarce worldwide due to persistent droughts, while consumption is rising steadily. This makes the thorough treatment of industrial wastewater all the more critical. However, the composition of industrial wastewater poses significant challenges for the pumps used.

As a global specialist in complex fluid management, NETZSCH Pumps & Systems offers you the optimal solution for low-wear pumping of abrasive industrial wastewater. Profit sustainably from the use of a service-friendly TORNADO® T.Envi® rotary lobe pump.

Pumps for the sustainable treatment of industrial wastewater

The treatment of industrial wastewater is highly demanding but has numerous advantages. On the one hand, the therapy extracts substances that are harmful to the environment and humans, and on the other hand, water losses are counteracted. A helpful by-product is a natural fertiliser produced during treatment, which can be used in agriculture. However, this requires powerful and low-wear pumps to convey the industrial wastewater. Because of its composition, industrial water is one of the most complex forms of wastewater. For example, when cleaning the mixing plants, the mineral wastewater produced by a large German manufacturer of building materials and concrete components contains pebbles up to 20 mm diameter. This wastewater has to be pumped out of the sedimentation tank via a riser pipe.

You don't want to change your industrial wastewater pump every six months?

For a long time, submersible gyroscopes were used to convey industrial wastewater in the building materials industry. However, the stones in the industrial wastewater and the abrasive sand ensured concise service lives due to the high speed required and the associated high maintenance costs. Due to excessive abrasion and wear, the pumps could no longer be used meaningfully after only about six months. To enable trouble-free treatment of such wastewater, NETZSCH developed a special pump that can withstand a wide variety of media. The robust and powerful TORNADO® T.Envi® rotary lobe pump can significantly extend your service life when pumping industrial wastewater.

Wastewater treatment: Pump with minimum maintenance requirements

The TORNADO® rotary lobe pump, individually designed to meet the requirements of industrial wastewater, not only reduces the downtimes of your systems but also minimises the maintenance effort. The basis for this is an innovative mix of materials. Instead of elastomer pistons in a metal housing, two hardened steel pistons rotate in an easily replaceable elastomer housing insert. As steel is less susceptible to material fatigue due to dynamic forces, more extended durability of the moving components is achieved. In addition, the metal expands less under the changing temperatures when pumping industrial wastewater, which is why tighter tolerances can be used in production, which is reflected in higher efficiency. The drive is a belt drive, which also synchronises the shafts and pistons.

The design thus gets by with a minimum of parts, which makes it very insensitive to malfunctions, simplifies maintenance and significantly reduces the necessary spare parts inventory compared to complex gearboxes. Previous checks showed almost no wear during pumping, despite the mineral components in the wastewater. Using a rotary lobe pump, you can sustainably treat even the most demanding industrial wastewater and thus effectively counteract the globally increasing water shortage.
