Component Specifications

Definition
The Top/Lid is a precision-engineered component that forms the upper closure of a separation bowl in centrifugal separation equipment. It ensures hermetic sealing during high-speed rotation, maintains internal pressure integrity, and often incorporates features for feed inlet, discharge outlets, or sensor integration. This component withstands significant centrifugal forces, pressure differentials, and corrosive media while maintaining dimensional stability.
Working Principle
The lid seals the separation bowl chamber during centrifugal operation, creating a closed system where centrifugal force separates materials by density. It maintains pressure containment, allows controlled material flow through integrated ports, and often includes balancing features to ensure rotational stability at high speeds (typically 3,000-15,000 RPM).
Materials
Stainless steel 316L (most common), duplex stainless steels (2205/2507), titanium alloys for corrosive applications, or aluminum alloys for lightweight requirements. Surface finishes: Ra ≤ 0.8 μm for sealing surfaces, with optional coatings like PTFE or ceramic for specific applications.
Technical Parameters
  • Diameter 150-800 mm
  • Flatness ≤ 0.1 mm/m
  • Seal Type O-ring, gasket, or metal-to-metal
