TORNADO^® Rotary Lobe Pump – special design for the petroleum industry

The NETZSCH TORNADO^® conveys your oil as well

In the petroleum industry NETZSCH TORNADO^® Rotary Lobe Pumps are used for the continuous, pressure-stable, gentle and low-pulsation handling of crude oil. The TORNADO^® can pump high capacities with a small footprint.

Features of the NETZSCH TORNADO^®:

large ball passage
self-priming
intermittent dry run capabilities
low-pulsation conveyance
high suction capability

The NETZSCH TORNADO^® offers you:

space-saving design
low life cycle costs
high efficiencies

Advantages of the NETZSCH TORNADO^®:

tolerates high pressures and capacities
can be operated with a great variety of substances
proportional capacity adjustment
various lobe geometries and materials, tailored to the given application
easy serviceability

1 Housing
Modular design with an adjustable housing for a long service life.

2 Wear Protection Plates
Highly abrasion-resistant, replaceable wear plates on both sides of the lobes.

3 Timing Gear
Patented timing gear design with GSS Technology creates positive separation between the pump head and product seals to prevent product leakage from infiltrating the timing gear.

4 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.

5 Housing Cover Plate
Rotary lobes, wear plates and mechanical seals can be easily serviced or exchanged after removal of the housing cover plate; it is not necessary to disassemble the pump housing or piping.

6 Rotary Lobes
Two-, three-, or four-lobe, straight or beveled rotary lobes in various elastomer qualities are available for different applications.

The NETZSCH TORNADO^® Rotary Lobe Pump is available…

in three models: MB, XB, XLB
for flow rates from 5 to 4500 gpm
for differential pressures up to 150 psi
with four rotary lobe models
with wear-proof and chemically resistant elastomers
with cast iron or stainless steel housing
with high-grade carbide mechanical seals

and conveys…

capacities from a few gpm to 4500 gpm
pressures of up to 150 psi in standard form
solid particles up to 2.75 inches
substances with a viscosity of 1 – 500,000 cPs

1 Rotor Setting Device

For positioning the rotors axially as well as radially.

2 Front Cover

For covering the pump head and correct positioning of the cover liner.

3 Cover Liner

For sealing the pump head and acting as abrasion resistant, replaceable wear plate. Two specially engineered elastomer inlays, one cover liner and one casing liner, protect the whole pump chamber from wear.

4 Rotor

Rotor with integrated sleeve in simple and robust shape. The lobe faces are completely flat, no screws where fibrous material can get trapped or compacted. The straight lobes allow much larger solids to pass.

5 Casing Liner

Wear resistant, replaceable casing liner with integrated Pulsation Reduction System (NETZSCH PRS). A glass fiber reinforced, robust body beneath the elastomer gives the liners stability and enables high suction and discharge pressure capabilities.

6 Rotor case

Rotor case with integrated flanges DIN and ANSI. Full access to pump head from flange to flange.

7 Bearing Housing

Bearing Housing with motor console and electric motor as compact pump unit. Other drive configurations are available.
