Product Specifications

Technical details and manufacturing context for WFI Distribution Manifold

Definition
The WFI Distribution Manifold is a critical component of a Vial/Syringe Washer system, responsible for receiving purified Water for Injection (WFI) from a central supply and evenly distributing it under controlled pressure and flow to the various spray nozzles, jets, or rinse stations within the washing chamber. It ensures consistent and thorough cleaning, rinsing, and final rinse cycles for pharmaceutical vials and syringes.
Working Principle
The manifold acts as a central hub with one inlet and multiple outlet ports. Pressurized WFI enters the inlet. Internal channels, valves, or flow restrictors within the manifold body regulate and divide the flow to ensure balanced delivery to each connected outlet line, which feeds individual cleaning nozzles in the washer.
Common Materials
316L Stainless Steel
Technical Parameters
  • Manifold body dimensions (e.g., length, width, port spacing) (mm) Customizable
Components / BOM
  • Manifold Body
    The main structure containing the internal flow channels.
    Material: 316L Stainless Steel
  • Sanitary Fittings (Tri-Clamp)
    Provide hygienic, secure connections for inlet and outlet tubing.
    Material: 316L Stainless Steel
  • Flow Restrictor/Orifice
    Optional component to ensure balanced flow to each outlet.
    Material: PTFE or 316L Stainless Steel
Engineering Reasoning
2.5-6.0 bar (36-87 psi) at 80-95°C
8.3 bar (120 psi) internal pressure at 121°C causes permanent deformation of 316L stainless steel manifold body
Design Rationale: Yield strength reduction of 316L stainless steel from 290 MPa at 20°C to 240 MPa at 121°C, combined with pressure-induced stress exceeding material yield point
Risk Mitigation (FMEA)
Trigger WFI temperature cycling between 80°C and 121°C during SIP cycles
Mode: Thermal fatigue cracking at manifold branch welds
Strategy: Finite element analysis-optimized weld geometry with 2.5mm minimum throat thickness and controlled cooling rate of 15°C/min post-welding
Trigger Particulate accumulation exceeding 15μm diameter at flow restriction points
Mode: Progressive flow reduction to below 85% of design specification
Strategy: Electropolished 316L stainless steel with Ra ≤ 0.38μm surface finish and 0.5% slope manifold installation

Frequently Asked Questions

What is the primary function of a WFI distribution manifold in pharmaceutical equipment?

The WFI distribution manifold distributes Water for Injection (WFI) to multiple cleaning stations or nozzles within vial/syringe washers, ensuring consistent and controlled water delivery for pharmaceutical cleaning processes.

Why is 316L stainless steel used for WFI distribution manifolds?

316L stainless steel is used because it offers superior corrosion resistance, meets pharmaceutical hygiene standards, and maintains water purity by preventing contamination in Water for Injection systems.
