310 Mini foam pumps from Shenzhen Pincheng Motor, are electronic mechanical devices designed to convert liquid solutions into uniform micro foam through a controlled aeration process. These compact systems integrate fluid dynamics and precision engineering to achieve reliable foam generation for hygiene, medical, and industrial applications.
Stage 1: Liquid Intake
The 3.7V micro foam pump draws liquid (soap, sanitizer, cosmetic base) from the reservoir through an inlet tube using negative pressure generated by the impeller's rotation. A pre-filter removes particulates >100μm.
Stage 2: Aeration
Simultaneously, air is introduced via:
a) Passive intake: Atmospheric air enters through dedicated ports
b) Active injection: Motor-driven micro-compressor
The liquid-air mixture reaches optimal 1:5 to 1:15 ratio controlled by flow restrictors.
Stage 3: Foam Generation
The turbulent mixture enters the foaming chamber containing layered mesh screens. As the solution passes through successive mesh layers (usually 3-7 stages):
Large bubbles are sheared into micro bubbles (50-200μm diameter)
Surface-active agents (surfactants) in the liquid stabilize the foam structure
Output consistency reaches 85-95% foam quality (liquid-to-foam ratio)
Stage 4: Delivery
Foam is expelled through an angled nozzle, with flow rate determined by:
Motor RPM (PWM-controlled in smart pumps)
Nozzle orifice diameter (typically 1-5mm)
Back pressure regulation (spring-loaded valves)
Industry Applications
Hygiene: Touchless soap/sanitizer dispensers (0.1-0.3mL/activation)
Beauty: Foam cleansers/mousse applicators (viscosity up to 2,000cP)
Food Service: Dishwasher pre-rinse foam (NSF-certified models)
Industrial: Precision adhesive foaming (2-component systems)
Maintenance Advantages
The brushless motor architecture eliminates carbon brush wear, while PTFE seals resist chemical corrosion. Typical MTBF exceeds 15,00 hours (>5 million cycles) with <0.5% foam consistency deviation.
