LongerPump JY15-12 Series Peristaltic Pump

Overview

The LongerPump JY15-12 Series Peristaltic Pump is a compact, ODM-grade precision fluid transfer solution engineered for integration into analytical instruments, medical devices, environmental monitoring systems, and automated laboratory platforms. Based on the proven peristaltic principle—where rollers compress flexible tubing to generate positive displacement—the JY15-12 delivers pulse-free, contamination-free flow without valves or seals, ensuring high biocompatibility and chemical inertness when paired with compatible tubing materials (e.g., silicone, Viton®, or PharMed® BPT). Its ultra-compact footprint (118 × 60 × 96 mm) and low-power DC input (11.4–25.2 V) make it ideal for space-constrained embedded applications requiring reliable, maintenance-light fluid handling up to 170 mL/min. Designed for industrial-grade reliability, the pump features a robust brushless DC motor, precision-machined pump head geometry, and thermally stable gear train—enabling continuous operation under variable load conditions typical in OEM instrumentation.

Key Features

• Modular control architecture supporting dual-mode operation: front-panel BCD thumbwheel switch (16 preset speeds from 1–100 rpm in discrete steps) combined with analog or digital external signal input
• Analog speed modulation via 4–20 mA (0.1–100 rpm), 0–5 V (0–100 rpm), 0–10 V (0–100 rpm), or 0–10 kHz (0–100 rpm) with linear response and ±0.5% full-scale repeatability
• RS485 Modbus RTU interface (optional) with user-configurable node address (DIP-switch range: 1–30; broadcast = 31) and selectable baud rate (1200 or 9600 bps), enabling daisy-chain integration into SCADA or PLC-controlled systems
• Dry-contact TTL-level inputs for bidirectional rotation control (NO/NC logic) and independent start/stop command—fully compatible with safety-rated interlock circuits
• High-resolution speed control at 0.1 rpm resolution, supporting fine-tuned calibration of flow rates across varying tubing inner diameters and viscosities
• Base-mount mechanical design with optional custom panel-mount adaptation, facilitating seamless integration into third-party enclosures or analyzers without structural modification

Sample Compatibility & Compliance

The JY15-12 series is compatible with standard peristaltic tubing sizes including #17 (ID 1.6 mm, max. flow 170 mL/min) and #25 (ID 2.4 mm, max. flow 118 mL/min), allowing users to optimize for flow rate, pressure head, or tubing lifespan depending on application requirements. While the pump itself does not carry CE, UL, or FDA certification as a standalone device, its electrical design complies with IEC 61000-6-3 (EMI emission) and IEC 61000-6-2 (immunity) standards. When integrated into final equipment, it supports compliance with ISO 13485 (medical devices), IEC 61010-1 (lab equipment safety), and GLP/GMP-aligned validation protocols—particularly where audit trails for flow parameters, runtime, and direction changes are required. Tubing selection must align with chemical compatibility charts and USP Class VI or FDA 21 CFR 177.2600 specifications for pharmaceutical or diagnostic use.

Software & Data Management

As an embedded OEM component, the JY15-12 does not include proprietary software or onboard data logging. However, its RS485 Modbus RTU interface enables native integration with industry-standard control environments—including LabVIEW™ (via NI-VISA), Python (with pymodbus), MATLAB® (Instrument Control Toolbox), and PLC ladder logic (Siemens S7, Allen-Bradley Logix). All communication frames support read/write access to real-time operational registers: current speed (rpm), direction status, run state, error flags (e.g., stall detection, overtemperature), and firmware version. For regulated environments, system integrators may implement 21 CFR Part 11-compliant electronic signatures and audit trails at the host controller level, capturing timestamped speed commands, direction transitions, and fault events with user attribution.

Applications

• Continuous-flow analyzers (e.g., nutrient analyzers, COD/TN/TP meters) requiring precise reagent dosing and sample aspiration
• OEM medical devices such as dialysis monitors, infusion pumps, and blood gas analyzers where tube-based isolation prevents cross-contamination
• Environmental sampling stations for groundwater, wastewater, or air scrubber effluent handling under unattended operation
• Chemical synthesis reactors requiring metered addition of catalysts or quenching agents in inert atmospheres
• Microfluidic platform priming and waste evacuation in benchtop diagnostic instruments
• Calibration systems for flow meters and sensors using gravimetric or volumetric reference standards

FAQ

What tubing sizes are supported, and how do they affect maximum flow rate?
The JY15-12 is optimized for #17 (1.6 mm ID) and #25 (2.4 mm ID) tubing. Maximum rated flow is 170 mL/min with #17 and 118 mL/min with #25, assuming water-like viscosity at 25 °C and nominal backpressure (<0.5 bar). Actual flow varies with fluid density, viscosity, tubing wall thickness, and system backpressure.

Can the pump be operated in reverse continuously, and what is the torque rating?
Yes—bidirectional operation is fully supported via dry-contact input. The motor delivers consistent torque in both directions; no derating is required. Rated stall torque is 25 mN·m at 24 VDC, sufficient for typical peristaltic loads with standard silicone tubing.

Is firmware upgrade capability available via RS485?
No—firmware is factory-programmed and non-upgradable in the current hardware revision. Future OEM versions may support field updates upon request.

Does the pump include built-in flow sensing or feedback control?
No—flow rate is inferred from calibrated speed-to-volume relationships based on tubing geometry and rotational speed. Closed-loop flow control requires external sensor integration (e.g., Coriolis, ultrasonic, or thermal mass flow meter) and host-level PID regulation.

What is the expected service life of the pump head and motor under continuous operation?
Rated for ≥10,000 hours MTBF (mean time between failures) at 25 °C ambient and 50% duty cycle. Tubing replacement interval depends on material and operating speed—typically 100–500 hours for silicone at 100 rpm.
