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.

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%.
