    Engineering Integration Notes

    1. Mounting and Spatial Orientation

    The 350 Mini Peristaltic Pump features a compact, two-hole mounting flange designed for seamless integration into tight enclosures. While the pump can be mounted in any orientation, we recommend a vertical motor alignment for applications involving high-viscosity fluids to minimize axial load on the motor shaft.

    • Pro-Tip: Ensure a minimum clearance of 15mm around the motor housing for optimal heat dissipation during continuous duty cycles.

    2. Motor Control and PWM Dimming

    To achieve variable flow rates, this pump is fully compatible with Pulse Width Modulation (PWM) controllers.

    • Voltage Range: Stable operation between 9V–13.2V (for 12V models) and 18V–26.4V (for 24V models).

    • Frequency Recommendation: Use a PWM frequency between 15kHz and 25kHz to eliminate audible motor whine and ensure smooth torque delivery at low RPMs.

    3. Tubing Maintenance and Replacement

    The 350 series utilizes a quick-release head design, allowing for tube replacement without disassembling the entire device.

    • Pre-Installation: Always apply a thin layer of silicone-based lubricant to the rollers to extend tubing life by up to 25%.

    • Inlet/Outlet Logic: To prevent backflow in precision dosing, ensure the suction line (inlet) is shorter than 0.5 meters to reduce vacuum load.

    4. Fluid Compatibility and Suction Lift

    This positive displacement pump is inherently self-priming.

    • Suction Lift: Capable of a dry prime lift of up to 2 meters.

    • Chemical Integration: For OEM projects involving aggressive detergents, we recommend the BPT (Norprene equivalent) tubing option, which offers superior gas permeability resistance and chemical shielding compared to standard silicone.

  • What is the maximum flow rate of the 350 Mini Peristaltic Pump?

    The 350 series is optimized for low-flow precision. Depending on the tubing size and motor speed (12V/24V), it typically delivers a stable flow range of 5ml/min to 95ml/min. For your specific OEM requirements, we provide custom calibration to ensure exact dosing accuracy.

    How long does the pump tubing last under continuous operation?

    Our standard BPT tubing is engineered for a long service life of over 1,000 hours, while silicone options offer cost-effective performance for shorter cycles. The 350 pump head itself is tested for 100,000+ cycles, ensuring industrial-grade reliability for soap dispensers and medical devices.

    Is the 350 series pump compatible with harsh chemicals or oils?

    Yes, compatibility depends on the tubing material. We offer BPT, Silicone, and Viton tubing. While silicone is great for water and detergents, BPT is superior for mild acids and bases. We recommend a 24-hour immersion test for specific chemical compatibility to ensure 100% safety.

    Can I use this mini pump for medical or food-grade applications?

    Absolutely. The 350 Mini Pump uses food-grade, biocompatible tubing that meets REACH and SGS standards. Since the liquid only touches the inside of the tube, there is zero risk of cross-contamination, making it ideal for lab equipment and food flavoring dispensers.

    What are the power requirements for the 350 Mini Peristaltic Pump?

    This pump is available in 12V DC and 24V DC versions. The low-power design makes it perfect for battery-operated devices or integrated PCB systems. It features a simple two-wire connection for easy “plug-and-play” installation in any compact OEM housing.
