LongerPump JL350-2J High-Flow Batch Transfer Peristaltic Pump

Overview

The LongerPump JL350-2J is an industrial-grade high-flow peristaltic pump engineered for continuous, reliable fluid transfer in production environments where volumetric accuracy, mechanical robustness, and operational safety are critical. Based on the positive displacement principle of peristalsis—where rotating rollers compress elastomeric tubing to propel fluid without contact between the pump mechanism and the medium—the JL350-2J delivers repeatable flow rates up to 35 L/min using compatible #92 silicone or thermoplastic elastomer (TPE) tubing. Its design prioritizes long-term stability over short-term throughput: the drum-shaped roller geometry and concave pressure block form a self-centering tube engagement system that minimizes lateral slippage and uneven compression, thereby reducing localized fatigue and extending tubing service life by up to 40% compared to conventional flat-roller configurations. The motor-inverter separation architecture enables flexible mounting in constrained or heat-sensitive enclosures, while the IP55-rated housing ensures resistance to dust ingress and low-pressure water jets—making it suitable for wet-process manufacturing lines, biopharmaceutical buffer preparation suites, and wastewater sampling stations.

Key Features

• High-capacity AC gearmotor paired with external variable-frequency drive (VFD) for precise speed control across 30–350 rpm, with 0.6 rpm resolution
• Self-aligning tube interface: drum-shaped rollers engage concave pressure blocks to maintain consistent occlusion geometry and prevent tube walk or torsion
• Adjustable tube compression gap for fine-tuning flow consistency and accommodating tubing batch variance
• Transparent polycarbonate safety guard enabling real-time visual verification of tube rotation, occlusion status, and potential kinking
• Dual-control architecture: local operation via tactile rotary knob and push-button interface; remote integration via analog (0–5 V / 0–10 V / 4–20 mA) and digital (dry-contact start/stop/direction) signals
• Full serial communication support: RS232 and RS485 interfaces compliant with Modbus RTU protocol for SCADA and MES-level integration
• Non-volatile power-loss memory: resumes pre-interruption speed, direction, and run state upon re-energization without manual reconfiguration

Sample Compatibility & Compliance

The JL350-2J is compatible with industry-standard peristaltic tubing materials including platinum-cured silicone (e.g., Norprene® A-60-F), reinforced TPE, and fluoropolymer-lined composites—subject to chemical compatibility verification per ASTM D471 and ISO 1817. It supports tubing inner diameters from 6.4 mm to 12.7 mm (e.g., #88 and #92 series), delivering calibrated flow ranges of 1.3–15 L/min and 3–35 L/min respectively. While not certified for sterile processing under ISO 13485 or FDA 21 CFR Part 820, its construction meets CE machinery directive (2006/42/EC) requirements and complies with IEC 60529 for IP55 environmental protection. For GMP-relevant applications, the pump’s analog and digital control inputs support audit-trail-capable PLC integration, and its deterministic speed response enables validation of flow profiles per USP Analytical Instrument Qualification guidelines.

Software & Data Management

The JL350-2J operates as a standalone hardware controller but is fully embeddable into automated process systems via standardized industrial protocols. Its RS485 port supports Modbus RTU register mapping for real-time readout of actual speed, direction status, fault codes (e.g., overcurrent, overtemperature), and accumulated runtime. When integrated with supervisory control software (e.g., Ignition SCADA, Siemens WinCC), the pump contributes timestamped flow metadata to centralized data lakes. Though no proprietary PC software is bundled, LongerPump provides open register documentation and sample Python/LabVIEW drivers for custom telemetry development. All analog control inputs are factory-calibrated to ≤±0.5% full-scale linearity, ensuring traceable flow setpoint fidelity across multi-pump synchronization scenarios.

Applications

• Continuous media dispensing in upstream bioprocessing (e.g., feedstock transfer to bioreactors, harvest line dilution)
• Chemical dosing in water treatment plants (coagulant, pH adjuster, disinfectant delivery)
• High-volume solvent circulation in extraction and purification skids
• Automated cleaning-in-place (CIP) loop priming and recirculation
• Batch transfer of food-grade syrups, dairy emulsions, and non-Newtonian sauces in hygienic manufacturing
• Environmental monitoring systems requiring ruggedized, low-maintenance fluid handling in field-deployed analyzers

FAQ

What tubing sizes are validated for maximum 35 L/min flow?
The #92 tubing (ID: 9.5 mm) is rated for 3–35 L/min at 350 rpm when used with silicone or TPE formulations meeting Shore A 50–60 hardness specifications.
Can the JL350-2J operate in a cleanroom environment?
While the IP55 enclosure provides dust and splash resistance, it is not rated for ISO Class 5–8 environments; optional stainless-steel shrouds and HEPA-filtered cooling paths are available as custom-engineered variants.
Is firmware upgrade capability supported via RS485?
No—firmware is stored in write-protected flash memory; updates require authorized service technician intervention using diagnostic hardware.
Does the pump meet electromagnetic compatibility (EMC) standards for industrial zones?
Yes—compliant with EN 61000-6-2 (immunity) and EN 61000-6-4 (emissions) for industrial environments.
How is tube life monitored or predicted?
No built-in wear sensor exists; however, consistent flow deviation >±3% at fixed speed indicates tubing fatigue, and recommended replacement intervals range from 200–500 hours depending on fluid abrasivity and operating pressure.
