Overview of Valveless Ceramic Plunger Pumps

Valveless ceramic plunger pumps are high-precision, corrosion-resistant fluid delivery devices widely used in the pharmaceutical, food, chemical, and semiconductor industries. Compared to traditional pumps, they offer superior wear resistance, corrosion resistance, and precise fluid control capabilities.

Structural Features of Valveless Ceramic Plunger Pumps

Key components of a valveless ceramic plunger pump include:

• Cylinder: Micron-level precision machining ensures accurate discharge volumes. Available materials include alumina (AL₂O₃) and silicon carbide (SiC).
• Plunger: Also micron-level precision machined, with material options such as SiC, AL₂O₃, and zirconia (ZrO₂).
• Pump Head Locking Screws: Secure the pump head for stable operation.
• Pump Head Placement Angle Scale: Allows adjustment of fluid output; maximum flow corresponds to 20°, while zero flow corresponds to 0°.
• Sealing Components:
  
  • Lip Seal: Enhances sealing performance and prevents leakage.
  • Cleaning Liquid Nozzle Seal Ring & Pump Head Seal Ring: Ensures a leak-free fluid channel.
  • Seal Seat: Optimizes sealing performance and extends service life.
• Pump Head: The core component ensuring stable fluid delivery.
• Nozzle: The fluid outlet ensuring precise delivery.
