Screw sampler type PREC 22

The screw sampler type PREC 22 is used to obtain a product sample by continuous rotation of the screw. The sampling process is divided into three steps :

Cleaning operation by the rotation of the screw

2.    Inversion of the rotation direction in order to take a sample from the product flow
3.    Evacuation of the sample

Technical Data :
  • Mild steel structure (other material available on request)

  • Flange mounting DN 125 / PN 10

  • Sampler body DN 2’’ with opening slot to catch the sample and integrated excess evacuation

  • Auger with ball bearing at one end (Possibility of cross length sampler with two bearings on request)

  • Dynamic tightness to prevent product leaks towards outside

  • Pipe connection DN 2’’ at 90° for sample discharge

  • Worm gear motor drive assembly, 250 W under 220/230 V three phases – 50 hz, IP 55

  • Maximum allowable grain size : 6 mm

  • Internal pressure : Atmospheric (Possibility to use isolation valves for pressure compensation, if required)

    Main Advantages :

    • Easy to set up and use

    • Specific dimension on request

    • Cleaning cycle before sampling phase
