Rotary Lobe Pump Systems

Our TORNADO® Rotary Lobe Pump are particularly designed to make dismantling, easier and cheaper. These pumps provide a good operation facility and are efficient in preventing the products being damaged. The rotating parts work on the principle of gear. Moreover, the accurate dimensions in drive shafts, bearings and timing gears guarantees smooth operation even under continuous full load.

Wide Spectrum of Applications The TORNADO® rotary lobe pump is used primarily for substances with the following properties:

• Low- to high-viscosity and abrasive substances (1 mPas to 1 million mPas)
• Substances with or without solid content (max. particle size of 70 mm)
• Thixotropic and dilatant
• Shear-sensitive
• Non-smearing or smearing

Additional Features:

• High suction capability of up to 8 mWC
• Intermittent dry run capabilities
• Reversible direction of rotation
• Vertical or horizontal installation
• Vibration-free, quiet running
• Low life cycle costs
• Simple operation by means of electronic motor control management

Large Range of Capacities and Pressures:

• Adjustable capacities up to 600 m³/h
• Pressures up to 5 bar, or optionally 10 bar

We have successfully attained the market credibility offering an unmatched quality TORNADO® Mobil Pumps. These are fabricated using premium quality stainless steel and rubber. Our range is corrosion resistant, high in performance; precision engineered and meets the international standards. Our Design – Your Advantage: Easy Serviceability, Dependability, Operating Safety.

• Housing Modular design with an adjustable housing for a long service life.
• Wear Protection Plates Highly abrasion-resistant, replaceable wear plates on both sides of the lobes.
• Timing Gear Patented timing gear design with decoupled gaskets for pump and gear reliably purges any product leakage and prevents infiltration into the timing gear.
• Shaft Seals Easy to service shaft seals with bi-directional and wear-resistant single-acting mechanical seals. Mechanical seals meeting DIN/ISO standards from any manufacturer can be installed.
• Housing Cover Plate Rotary lobe, pump and gear seals can easily be serviced or exchanged after removal of the housing cover plate; it is not necessary to disassemble the pump housing or piping.
• Rotary Lobes Two- to four-bladed, straight or beveled rotary lobes in various elastomer qualities are available for different applications.
