, transporting aggressive fluids safely is a core requirement. For engineers evaluating the PinMotor 310 series
The secret to long-term reliability lies in selecting the correct -the components in direct contact with the fluid.
Elastomers (diaphragms) absorb fluid, causing pressure loss or motor seizure.
Materials crack over time, leading to hazardous leaks.
Aggressive solvents can literally dissolve inferior plastics.
The PinMotor 310 series utilizes a , allowing you to customize the diaphragm and valves to match your specific chemical profile.

1. EPDM: The Standard for Disinfection
EPDM is the most versatile choice for the 310 series. It is highly resistant to 70%-95% Ethanol and Isopropyl Alcohol, making it the industry standard for automatic soap dispensers and surface sanitizing equipment.
2. FKM (Viton): For Aggressive Industrial Fluids
is the premium solution. FKM-equipped 310 pumps are designed for high-durability environments where EPDM would otherwise degrade.
3. Silicone: Purity and Flexibility
Best suited for medical-grade neutral fluids. While excellent for thermal stability, , as it is prone to rapid swelling.
Chemical reactions accelerate at higher temperatures. A material resistant to a disinfectant at 20℃50℃. Always evaluate compatibility based on your system's maximum operating temperature.
For mission-critical applications, PinMotor recommends a 72-hour soak test:
Submerge a sample of the 310 diaphragm/valve in the target fluid.

5-10% suggests a need for a more robust material like FKM.
Q: Can the 310 pump head itself withstand acids?
A: Yes. In addition to the elastomers, we offer pump heads in , which provide much higher chemical resistance than standard ABS plastics.
Q: Is the 310 series suitable for bleach (Sodium Hypochlorite)?
pump head. Bleach is highly oxidative, so material matching is essential.
