About us

Houttuin''s original design provided the blue print for today''s twin screw positive displacement rotary pumps. Based on the Archimidean principle, two intermeshing screws on parallel shafts operate inside a close fitting, 8-shaped liner. Liquids are pumped from both ends into the pump''s centre body where the discharge is located. The long shaft through a set of external precision timing gears drives the short shaft. Houttuin twin screw pumps feature a clearance between the screws. The major advantages of this design are:

 

  • less wear on the screws
  • less chance of liquid contamination
  • reduced risk of damage
