Customized Color 24mm 28mm 2cc Stable Quality Hand Washing Liquid Dispenser Left-right Lotion Pump

Functional Architecture

A lotion pump operates on a reciprocating piston principle, comprising:

• Activation Mechanism

  • Manual actuator (typically 20–30mm diameter) requiring 2–5N of force for operation

  • Stroke length optimized for 0.3–1.5mL discharge per cycle

• Fluid Dynamics System

  • High-density polyethylene (HDPE) dip tube (ID 2–4mm) with surface tension-breaking design

  • Precision-molded PP or ABS housing with ≤0.05mm manufacturing tolerances

  • Dual-stage silicone check valves (inlet and outlet) with 0.2–0.5psi cracking pressure

• Dosing Control

  • Standard models deliver 0.7–1.2g/activation (viscosity-dependent)

  • Metered versions maintain ±5% dosage accuracy across 10,000+ cycles
