Mechanical Design of a Spring-Loaded Diaphragm Pump (Fluid Displacement System) Anyone
About the job
I am looking for a Mechanical Engineer or Product Designer to create a CAD model (SolidWorks/Fusion 360) and a Bill of Materials (BOM) for a purely mechanical, top-initiated liquid spray pump.
Project Overview: The goal is to create a sort of disinfecting spray station. The device consists of a 15 cm diameter cylindrical tank (approx. 10cm in ht) that sprays a soapy water solution upward when a "Floating Ring" actuator is depressed.
Design Specs & Requirements:
Actuation: A concentric "Floating Ring" design. The spray nozzle must remain fixed in the center while the ring moves downward around it to initiate the spray.
Containment: An outer wall should extend 5cm above the actuator plate to contain overspray/splash.
Pump Mechanism: A displacement pump (Piston or Diaphragm) using two one-way check valves (Inlet/Outlet).
Performance: Target spray height of 5-8 cm. I have calculated a required spring constant of approximately approx 600 N/m but I would like you to verify this based on your final pump chamber volume.
Materials: Must be designed for a "soapy water" environment (use of Stainless Steel 316, Silicone/EPDM, and 3D-printable resins/plastics).
Standard Parts: Prioritize the use of "Off-the-shelf" components for springs, O-rings, and check valves to simplify prototyping.
Deliverables:3D CAD Assembly: (STEP and native Fusion 360/SolidWorks files).
Exploded View: A simple PDF showing how the components assemble.

BOM (Bill of Materials): A list of all off-the-shelf components with suggested part numbers.
DFM Advice: Brief notes on the best 3D printing method (SLA/MJF) to ensure the tank and pump housing are water-tight.
Preferred Qualifications: Experience in fluid dynamics or small-scale pump design. Knowledge of seals, gaskets, and chemical compatibility (surfactants).
Portfolio demonstrating "Design for Manufacturing" (DFM) for 3D printing or injection molding. read less
