Packaging Procurement | An Article to Help You Quickly Grasp the Technical Principles, Production Processes and Application Scenarios of Lotion Pumps in Detail
A conventional lotion pump head is usually composed of components such as a pressing nozzle/head, upper pump column, locking cap, gasket, bottle cap, pump plug, lower pump column, spring, pump body, glass ball, and suction tube. Depending on the structural design requirements of different pumps, the relevant components may vary, but their principles and ultimate purposes are consistent, which is to effectively take out the contents.
The majority of pump head components are primarily made from plastic materials such as PE, PP, and LDPE through injection molding. The main components of the pump head can undergo processes such as electroplating, anodized aluminum coating, spraying, and injection coloring.
- Conventional diameters: Ф18, Ф20, Ф22, Ф24, Ф28, Ф33, Ф38, etc.
- Classified by structure: external spring pump, plastic spring pump
- Classified by pumping volume: 0.15/0.2cc, 0.5/0.7cc, 1.0/2.0cc, 3.5cc, 5.0cc, 10cc and above
Key performance metrics include:
- Number of priming strokes
- Dispensing volume per stroke
- Pressing force required
- Torque for opening the pump head
- Rebound speed
- Inlet flow rate
- External Spring: Does not contact the product, eliminating risk of contamination from rust.
- Single-dose volume controlled by adjusting chamber size (typically 0.3–5mL) and piston stroke.
- Accuracy within ±5%, suitable for precise dispensing of various viscosities.
