The 310 micro pump is a critical component in precision fluidic systems. Whether you are designing a medical monitor, a beauty device, or a smart household appliance, understanding the performance limits-flow rate, pressure, and vacuum-is essential for system reliability.
This guide provides a technical analysis of the 310 series specifications to help engineers make informed procurement decisions.
1. Key Performance Specifications of 310 Series
The performance of a 310 micro diaphragm pump is primarily determined by its motor speed and the displacement volume of the pump head.

2. Factors Affecting 310 Pump Performance
In real-world B2B applications, the "Free Flow" rate is rarely the actual operating flow. You must consider:
Voltage Regulation: A 12V 310 pump running at 9V will see a significant drop in flow but an increase in lifespan.
Back Pressure (Load): As the system resistance increases, the flow rate decreases. PinMotor provides optimized Q-P curves to help you find the "Sweet Spot" for your device.
Diaphragm Material: We offer EPDM, Silicone, and Viton options. The choice of material affects chemical resistance and air-tightness, which directly impacts vacuum stability.
3. Industry Applications: Where 310 Pumps Excel
The compact size (approx. 73g) and high efficiency make the 310 series the "Gold Standard" for:
Medical Equipment: Electronic blood pressure monitors, portable oxygen concentrators, and wound therapy devices (NPWT).
Beauty & Personal Care: Blackhead removers (vacuum suction), facial misters, and automatic foaming soap dispensers.
Environmental Monitoring: Portable gas samplers and air quality analyzers.
Household Appliances: Coffee machines and water circulation in smart appliances.
