TORNADO® Industrial Rotary Lobe Pumps T2

NETZSCH TORNADO® industrial rotary lobe pumps are versatile stand-alone equipment. Used primarily in environmental technology and the chemical industry, these pumps handle almost any substance continuously and gently while metering in proportion to rotation speed.

Dependable conveyance with no overflow

NEMO® Immersible Pumps are used for emptying barrels, tanks, and pits. They are also used where space is limited and the danger of cavitation may be present. In addition, these pumps are suitable for emptying barrels containing materials hazardous to water and the environment.

Downstream – NEMO® Multiphase Pumps

Only very seldom does crude oil arrive at the surface in pure form. Usually it is mixed with water, sand and gas. Conventional pumps require that the gas first be separated from the crude oil however, not with NETZSCH NEMO® Multiphase Pumps. NEMO® Multiphase Pumps can be used for crude oil with a gas content of up to 100%.
