LongerPump JY15-24 Series ODM Dual-Channel Peristaltic Pump

Overview

The LongerPump JY15-24 Series ODM Dual-Channel Peristaltic Pump is an engineered solution for precise, low-profile fluid handling in embedded instrumentation and analytical equipment. Based on the positive displacement principle of peristaltic pumping—where rollers compress flexible tubing to generate unidirectional flow—the JY15-24 delivers repeatable, pulse-free transport without fluid contact with mechanical components. Its compact form factor (129 × 82 × 90 mm) and modular design make it ideal for integration into OEM medical devices, environmental analyzers, chemical dosing systems, and laboratory automation platforms requiring dual independent flow paths. Each channel operates at up to 43 mL/min under standard conditions, with inter-channel flow deviation maintained within ±3%—a specification validated across operating speeds from 0.1 to 100 rpm and verified under controlled temperature (0–40 °C) and humidity (<80% RH) environments.

Key Features

• Dual-Independent Channel Architecture: Two mechanically isolated pump heads driven by a shared motor assembly, enabling synchronous or asynchronous operation with minimal cross-talk and calibrated flow matching.
• High-Resolution Speed Control: 0.1 rpm speed resolution across a 0.1–100 rpm range, achieved via 16-position BCD DIP switch selection or linear analog input (4–20 mA, 0–5 V, 0–10 V, 0–10 kHz).
• Flexible Integration Interfaces: Supports dry-contact TTL-level inputs for direction reversal (NO/NC) and run/stop commands; optional RS485 Modbus RTU communication with user-configurable address (1–30) and baud rate (1200/9600 bps).
• Robust Power & Environmental Design: Operates on wide-range DC input (11.4–25.2 V), rated at 20 W maximum consumption; certified for continuous operation in ambient temperatures from 0 °C to 40 °C and non-condensing humidity below 80% RH.
• OEM-Optimized Mechanical Layout: Standardized baseplate and front-panel mounting compatibility simplifies mechanical integration into custom enclosures; no external cooling or vibration isolation required under nominal load.

Sample Compatibility & Compliance

The JY15-24 series accommodates industry-standard silicone or thermoplastic elastomer tubing sizes including ID 13# (1.6 mm), 14# (2.4 mm), 16# (3.2 mm), and 19# (4.8 mm), with maximum single-channel flow rates ranging from 4 to 27 mL/min depending on tubing wall thickness and elasticity. While the pump itself does not carry CE, UL, or FDA clearance as a standalone medical device, its design adheres to IEC 61000-6-2 (immunity) and IEC 61000-6-4 (emission) standards for industrial environments. When integrated into final equipment, the system may be validated against ISO 13485 (for medical devices), ASTM D3418 (viscoelastic characterization of elastomers), or USP (elastomeric components in pharmaceutical processing), subject to end-user qualification protocols.

Software & Data Management

The JY15-24 series does not include proprietary software or onboard data logging. Instead, it is designed for deterministic, real-time control via external PLCs, microcontrollers, or DAQ systems. Analog inputs provide closed-loop speed feedback capability when paired with compatible ADC modules. For RS485-equipped variants, Modbus RTU register mapping supports read/write access to operational status (running/stopped), direction flag, current speed setpoint, and fault codes (e.g., stall detection, overtemperature warning). Audit trails and electronic records—required under FDA 21 CFR Part 11 or EU Annex 11—must be implemented at the host system level, as the pump provides no internal timestamping, user authentication, or non-volatile configuration storage.

Applications

• Continuous-flow chemistry reactors requiring synchronized reagent delivery.
• On-line water quality analyzers (e.g., COD, NH₃-N, phosphate) with dual-sample/dual-calibration loops.
• Point-of-care diagnostic instruments needing metered aspiration and dispensing of whole blood or serum.
• Cell culture bioreactor feed-and-bleed subsystems where contamination avoidance mandates tube-based fluid isolation.
• Automated calibration stations for gas chromatography or ion chromatography systems.

FAQ

What tubing sizes are supported, and how does tubing selection affect flow accuracy?
The JY15-24 supports 13#, 14#, 16#, and 19# tubing. Flow rate scales nonlinearly with inner diameter and wall thickness; users must calibrate volumetric output per tubing lot using gravimetric or timed-collection methods per ISO 8599 or ASTM D1298.
Is the pump suitable for sterile or high-purity applications?
Yes—provided tubing is certified for USP Class VI, ISO 10993, or EP 3.1.2 use. The pump head does not contact fluid; however, end-users must validate tubing leachables and extractables per ICH Q5A/Q5D guidelines.
Can both channels operate at different speeds simultaneously?
No—the JY15-24 uses a single motor and gear train; both channels share identical rotational speed. Independent speed control requires two separate pump units or a multi-channel controller.
Does the RS485 interface support Modbus TCP or only RTU?
Only Modbus RTU over RS485 physical layer is supported. No Ethernet or TCP/IP stack is embedded.
What is the expected service life of the pump head under continuous operation?
With proper tubing selection and maintenance (roller replacement every 10,000 hours, tubing change per manufacturer’s cycle), mean time between failures exceeds 20,000 hours at 50% duty cycle and 25 °C ambient temperature.
