Gentle Conveyance of Fruit and Vegetables:

NEMO® Progressing Cavity Pumps Convey Fruit Gently and in One Piece

When it comes to conveying systems in the foodstuff industry a careful transportation of the medium is a frequent precondition.

Look behind the scenes

A big problem for economic conveying of foodstuff is the sensitivity of the majority of the raw materials. Pumps that develop pressure or heavy shearing forces on the medium, can result in the conveyed goods being impaired or even destroyed. This is particularly applicable to fruit and vegetables.  

Challenge accepted

A large cider mill had to struggle with the fact that their apples and pears should be pre-cut during transportation from the receiving hoppers to the mills and the system utilized excessively squashed and partly milled the goods. Therefore, the valuable juice already escaped into the filling hopper and was lost for further processing – at approximately 1000 t of fruit per day, a noticeable cost factor.    

Excellently solved

A NEMO® progressing cavity pumps was selected for the apples and pears that come into the hopper in one piece that can easily overcome solids of up to 10 cm diameter. Furthermore, in order to pre-cut the fruit and move the pieces to the aperture of the conveying area – as required by the user – the coupling rod, which transmits the torque from the drive to the rotor, is equipped with an appropriate special feeding screw. In this manner, cutting and conveying is ensured without crushing, which minimizes premature escape of the juice. Approximately 60 m³ of fruit is transported every day by the new pump.

NEMO® BF Progressing Cavity Pump with Hopper and Feeding Screw

The NEMO® BF is used in all branches of industry to provide continuous, pressure-stable, gentle and low-pulsation conveyance with dosing in proportion to rotation speed. It is employed primarily for highly viscous, compacted and crumbly substances that do not have a tendency to bridge.

NETZSCH Barrel Emptying Pumps

NEMO® barrel emptying pumps suction themselves automatically to the bottom of the barrel or container to achieve almost residue-free emptying in the chemical, pharmaceutical and foods industries. 


NEMO® BY progressing cavity pumps can be used in any area of industry where a great variety of different substances must be pumped or very precisely dosed.

NEMO® BH Hygienic Pump

The NEMO® BH is employed in the foodstuff, pharmaceutical, cosmetic and chemical/biochemical industries for hygienic applications and optimal cleaning. It is ideal in these settings due in part to its continuous, pressure-stable, gentle and low-pulsation conveyance and in part to its capability of dosing in proportion to speed.

NEMO® BO/BS Pump with Hopper in Block Construction and Flanged Drive

The NEMO® BO/BS progressing cavity pump with square/rectangular hopper and coupling rod with feeding screw and force-feed chamber is employed in almost all branches of industry to provide continuous, pressure-stable, gentle and low-pulsation conveyance.
