TORNADO T1 Rotary Lobe Pump


Designed to produce high flow at low to medium pressures in a small compact package, the TORNADO T1 rotary lobe pump can handle a wide range of viscosities, solids, temperature, abrasion, and corrosive/acidic process fluids and environments.


It is extremely versatile for just about any orientation and installation. Its robust design offers longevity, operational flexibility, and dry-run capabilities. It allows the pump to operate and handle many upset process conditions without causing harm to the pump. The pumps are available up to over 4,000 gpm and up to 130 psi.


TORNADO T1 is a Full Service-in-Place pump. The front pullout design allows for easy access for maintenance and inspection. Opening the front cover allows access to the wear plates, lobes, and seals. Additionally, there is no need to access the timing gears or bearing as they are protected with the NETZSCH Gearbox Security System (GSS). This feature protects the gearbox from the process side of the pump (wet-end). The GSS is an air gap that exists between the mechanical seal and the lip seal of the timing gearbox that establishes a physical separation between them. Should the mechanical seal leak, no product can get into the pump’s gearbox to contaminate the timing gear oil.


Upgrades include improved flange sealing, a one-piece housing design, additional seal configurations (single, double, flush, quench, etc.), a superior wear plate, and newer materials and coatings that extended operation life.
