Netzsch is supplementing its progressing cavity pumps portfolio with a model that has a hopper and cutting device, allowing solids such as pieces of fruit and vegetable, to be conveyed and cut in one process step.
The NEMO BO/SO progressing cavity pump has a hopper and a coupling rod with feeding screw and force-feed chamber, which also houses the cutting unit. The pump can be used in many industries but primarily within food processing, where continuous, pressure-stable, gentle and low-pulsation conveyance of cut media is required.
The attached hopper ensures an efficient supply of the medium to the conveying elements. By passing the cutting unit in the feeding chamber larger pieces of the medium are cut immediately. The cutting unit contains a rotating knife fixed on the coupling rod, which is equipped with three blades and a variable number of stationary knives. The number of knives can be adapted to the size and consistency of the particles.
The NEMO BO/SO hopper pump with cutting device can also dose the conveyed medium in proportion to the speed of rotation.
