How Twin Screw Pumps Work
1.1 Operating Principle
Two intermeshing helical screws rotate in opposite directions, creating axial movement that gently transfers product from suction to discharge.
Key Advantages:
- Non-contact between screws/casing: Reduces wear even at high speeds (up to 3,000 rpm).
- Self-compensating: Maintains consistent flow regardless of pressure changes.
1.2 Hygienic Design
- Fully drainable: Eliminates residue for CIP/SIP processes.
- Surface finish Ra ≤ 0.8 μm: Complies with EHEDG and 3A standards.
