Product Applications
| Application Scenario | Key Benefit for the Design | Recommended Input |
| Touchless Hand Washers | High self-priming suction allows the pump to be placed above the liquid tank, preventing backflow and leakage. | 3.6V - 4.2V Li-ion |
| Hotel Wall-Mounted Dispensers | Consistent foam density (12:1 ratio) reduces liquid waste and ensures a premium "creamy" hand-feel for guests. | 5V / 6V DC Adapter |
| Portable Foaming Devices | Extremely compact footprint (310-series motor) fits into slim, handheld, or travel-sized product housings. | 3.7V Battery |
| Public Sanitizer Stations | High-cycle life (50,000+ operations) ensures reliability in high-traffic environments like offices or malls. | 6V (4x AA Alkaline) |
| Medical/Lab Wash Stations | SGS/RoHS/REACH compliance ensures material safety and prevents chemical reaction with specialized soaps. | 5V Regulated Power |

Manufacturing Quality & Compliance
At Pinmotor, we prioritize rigorous quality control to ensure seamless integration into your high-volume production lines. Our manufacturing facility and the PYFP310-XG series comply with the most stringent global automotive and environmental standards:
ISO 9001:2015 Certified
Our quality management system ensures consistent product output, from raw material inspection to final functional testing of every foam pump.
IATF 16949 Compliant
We leverage automotive-grade process discipline to guarantee ultra-low defect rates and long-term reliability in consumer electronic applications.
RoHS & REACH Fully Compliant
All materials used in the 310G series—including the motor brushes, diaphragm, and housing—are free from hazardous substances, ensuring your end-product is ready for the EU and North American markets.
Technical Note: Full documentation, including material safety data sheets (MSDS) and compliance certificates, is available upon request for your engineering audit.
We supply more than just product, we engineer solutions optimised to suit your application requirements.
Q1: Can the 310G pump handle high-viscosity soap or gel without clogging?
A: The 310G is specifically designed for liquid foam soap. While it has strong self-priming capabilities, using high-viscosity gels without proper dilution (typically a 1:3 or 1:5 ratio) may increase motor load and affect foam density. For optimal performance, we recommend using standard foaming liquids with consistent viscosity.
Q2: How does the 3.6V rating perform when the lithium battery voltage drops? A: This motor is optimized for the 3.2V – 4.2V range of single-cell lithium batteries. Unlike generic pumps, the 310G maintains a stable torque output at 3.0V, ensuring that the foam consistency remains professional even when the device’s battery is nearing its recharge cycle.
Q3: What is the typical service life of this pump in a household environment?
A: Under standard lab testing conditions (2 seconds on, 5 seconds off), the 310G pump exceeds 50,000 cycles. In a typical household setting of 10-15 uses per day, this translates to a service life of over 8 years, depending on the chemical composition of the soap used.
Q4: Is the noise level low enough for high-end hotel or office installations?
A: Yes. The pump is engineered with an internal dampening system that limits operational noise to ≤55dB at a 30cm distance. When properly mounted within a plastic housing using silicone gaskets, the perceived noise is significantly reduced, meeting the requirements for premium, “silent” bathroom fixtures.
Q5: Can Pinmotor customize the wire length and connector type for this model?
A: Absolutely. We provide OEM/ODM services for the 310G series. This includes custom lead wire lengths, specific terminal connectors (like JST or PH series), and even adjustments to the air-liquid ratio to match your specific soap bottle design. Standard samples for testing can typically be shipped within 3-5 business days.
