Houttuin Pumps specializes in low-pressure two-screw technology. The manufacturing operations are located in Utrecht, Netherlands. Houttuin's original design provided the blueprint for today's twin screw positive displacement rotary pumps.
Based on the Archimidean principle, two inter-meshing screws on parallel shafts operate inside a close fitting, 8-shaped liner. Liquids are pumped from both ends into the pump's center 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 |
