LongerPump T-S109 & WX10-14 ODM Peristaltic Pump Module

Overview

The LongerPump T-S109 & WX10-14 is an OEM/ODM-integrated peristaltic pump module engineered for precise, low-flow fluid handling in analytical instrumentation, medical devices, environmental monitoring systems, and laboratory automation platforms. Based on the classic roller-type peristaltic principle—where rotating rollers compress elastomeric tubing to generate positive displacement—the unit delivers pulse-free, contamination-free flow without valving or seals. Its compact footprint (107 × 60 × 80 mm) and modular architecture enable seamless integration into space-constrained instrument enclosures. Designed for continuous duty in ambient lab or industrial control environments (0–40 °C, <80% RH), the pump operates exclusively via external step pulse and direction signals, eliminating onboard control logic to maximize system-level design flexibility.

Key Features

• Integrated WX10-14 pump head with optimized roller geometry for uniform tube compression and extended tubing life
• High-torque 2-phase hybrid stepper motor (1.8° step angle, 9 V rated, 0.6 A phase current) ensuring stable low-speed operation down to single-step resolution
• Flow range calibrated up to 24 mL/min using standard silicone or PharMed® BPT tubing (ID ≤3.17 mm, wall thickness 0.8–1.0 mm)
• Standard 4-wire unipolar interface (Red=A, Green=Common, Yellow=B, Blue=Common) compatible with common motion controllers and microcontroller GPIOs
• Baseplate-mount configuration with pre-drilled holes; optional panel-mount adaptation available upon OEM specification
• No internal electronics or firmware—fully deterministic behavior under host-controlled step/direction timing

Sample Compatibility & Compliance

The T-S109 & WX10-14 transports fluids solely through mechanical occlusion of certified peristaltic tubing, making it inherently compatible with aqueous solutions, buffers, reagents, cell culture media, and mild organic solvents—provided tubing material compatibility is verified per ISO 10993 or USP Class VI standards. It supports tubing materials including platinum-cured silicone, Viton®, and thermoplastic elastomers (TPE), each selected per chemical resistance and biocompatibility requirements. While the pump itself carries no CE, UL, or IEC 61000 certification as a component-level device, its electrical parameters (9 V DC, <5 W total power draw) align with functional safety boundaries for Class II embedded subsystems. When integrated into final equipment, compliance with IEC 61010-1 (safety) and IEC 61326-1 (EMC) remains the responsibility of the end-system manufacturer.

Software & Data Management

As a dumb actuator module, the T-S109 & WX10-14 does not include embedded firmware, USB, or serial interfaces. Flow rate and direction are controlled entirely by externally generated step pulses (frequency determines speed; polarity or dedicated DIR line sets direction). Integration with host systems—such as LabVIEW, Python-based control frameworks (e.g., PySerial + GPIO libraries), or PLC ladder logic—is achieved via TTL-compatible digital I/O. For audit-trail applications requiring traceability (e.g., GLP-compliant analyzers), full control logging—including step count, cumulative volume estimates, and motor enable/disable timestamps—must be implemented at the host controller level. No proprietary drivers or SDKs are required or provided.

Applications

• Reagent delivery in benchtop spectrophotometers and colorimeters
• Sample aspiration and diluent metering in automated titrators and ion-selective electrode systems
• Continuous infusion in portable blood glucose monitors and point-of-care diagnostic cartridges
• Calibration fluid circulation in online water quality sensors (pH, conductivity, turbidity)
• Low-shear media transfer in bioreactor control modules and microfluidic platform priming circuits
• OEM integration into environmental air samplers, where pulsation-free flow ensures accurate particulate collection efficiency

FAQ

Is the T-S109 & WX10-14 suitable for sterile or pharmaceutical-grade fluid handling?

Yes—when paired with USP Class VI-certified tubing and installed in ISO 5/Class 100 cleanroom-validated enclosures, it meets baseline requirements for non-contact fluid transfer in QC labs. Final validation remains the responsibility of the equipment integrator.
Can flow rate be precisely calibrated for volumetric accuracy?

Yes—flow is linearly proportional to motor speed within the specified 0–60 rpm range. Calibration against gravimetric or timed-collection methods yields typical repeatability of ±2% CV over 24-hour continuous operation, assuming constant tubing elasticity and temperature.
Does LongerPump provide custom firmware or closed-loop speed feedback?

No—this is a fixed-function stepper-driven module. Encoders or Hall-effect feedback must be added externally by the system designer if closed-loop velocity control is required.
What tubing brands and part numbers are validated for use with this pump head?

LongerPump validates performance with Norprene® LFT-25, Masterflex® 96410-xx, and Pharmapure® 201 series tubing. Full compatibility matrices—including pressure drop vs. flow curves—are available under NDA for qualified OEM partners.
