Head-Plate-Drive model B

HPD-B drive adapter for Biostat design

Head-Plate-Drive (HPD) interfaces CellVessel SUB and BactoVessel SUF to late Sartorius® Biostat rubber coupling design - which we call ID39-B. Used by CerCell®, Finesse®, BBI-biotech and others. Insure the servo motor is fully alligne. Insure max servo motor weigth is 1,5 kilo up to OD150 and 1,8 kilo up to OD250.

The re-usable SUB/SUF adapter kit consist of 2 parts;

  • Aluminium HPD-B adapter to be pressed, rotated gently CW onto the OD30 mm HPD bearing house
  • White Nylon66 SP21 PowerGrip sprocket which fit onto the OD 8,0 mm SS axle

Shown example is a CellVessel OD 130x255 3 litre SUB mounted with Kollmorgen® AKM servo motors in HPD-B setup. The SP21 rubber coupling part are attached to the re-usable PowerGrip Nylon sprocket. Here CellVessel OD 130x225 3 litre SUB mounted with the white Nylon PowerGrip sprocket on the central OD 8,0 mm axle and the adapter on the OD 30 mm HPD bearing housing. Manual mounting of the PowerGrip® Nylon sprocket to the central axle and mounting of the aluminium HPD adapter is simple.

Several Biostat coupling standard exist;

  • very old Biostat for Heidolph - now obsolete - conversion to ID39-B though possible
  • old Biostat magnetic for Kollmorgen 6SM - must be converted to ID39-B
  • newer Biostat with rubber coupling for Kollmorgen AKM being the ID39-B format
  • latest Biostat with rubber coupling for Pabst being the ID39-B format
