LongerPump YZ35-13 Industrial Quick-Install Peristaltic Pump Head

Overview

The LongerPump YZ35-13 is an industrial-grade, quick-install peristaltic pump head engineered for continuous-duty fluid transfer in demanding manufacturing, chemical dosing, bioprocessing, and water treatment applications. It operates on the fundamental principle of peristalsis—where rotating rollers sequentially compress flexible tubing against a rigid housing to generate positive displacement flow without fluid contact with moving mechanical parts. This design ensures contamination-free operation, eliminates the need for valves or seals, and provides precise, pulse-dampened volumetric delivery. The YZ35-13 is purpose-built for integration into OEM systems and automated production lines, supporting both standalone and multi-head configurations via mechanical daisy-chaining. Its robust architecture enables reliable performance under extended operational cycles, with thermal stability up to 120 °C (dependent on tubing selection) and resistance to chemical exposure when paired with compatible elastomeric tubing.

Key Features

• Two standardized tube retention methods: continuous-length tubing clamping and pre-terminated tubing connector clamping—enabling rapid adaptation to diverse fluid path architectures.
• Tool-free, one-step tube loading mechanism with self-aligning roller geometry and micro-adjustable occlusion gap control for optimized tube compression and service life extension.
• Three-roller configuration with hardened stainless-steel rollers mounted on precision-ground shafts, delivering uniform compression force and minimizing tube fatigue.
• PSU (polyphenylsulfone) housing offering high tensile strength, dimensional stability across temperature fluctuations (–40 °C to +180 °C short-term), and inherent flame retardancy (UL94 V-0 rated).
• Modular mounting interface compliant with ISO 2160 and DIN 32300 standards, facilitating direct coupling to NEMA 23/34 stepper or servo motor drives.
• Weight-optimized structural design (1.65 kg) without compromise to rigidity—reducing vibration transmission and enabling compact system integration.

Sample Compatibility & Compliance

The YZ35-13 accommodates industry-standard peristaltic tubing sizes #73 and #82 (inner diameters ~3.2 mm and ~6.4 mm respectively), compatible with Pharmed BPT, Norprene®, Tygon® LFL, and silicone formulations meeting USP Class VI and FDA 21 CFR 177.2600 requirements. Tube compatibility has been validated per ASTM D2240 (Shore A hardness) and ISO 8536-4 (infusion equipment). The pump head itself carries CE marking for machinery safety (2006/42/EC) and conforms to RoHS 2011/65/EU and REACH (EC 1907/2006) material restrictions. While not certified as intrinsically safe, it may be deployed in Zone 2/Class I, Div 2 environments when installed with appropriate motor enclosures and grounding protocols.

Software & Data Management

As a mechanical pump head, the YZ35-13 does not incorporate embedded electronics or firmware. It functions as a passive fluid-handling component within larger control ecosystems. When integrated with LongerPump’s LTS series controllers or third-party PLCs (e.g., Siemens S7, Allen-Bradley CompactLogix), flow rate is regulated via analog 0–10 V or 4–20 mA input, or digital pulse commands (RS-485 Modbus RTU). Full audit trail capability—including occlusion history, runtime logging, and maintenance alerts—is achievable only at the system level through compliant SCADA or MES platforms adhering to FDA 21 CFR Part 11 and Annex 11 requirements. Documentation packages include IQ/OQ templates aligned with GMP Annex 15 guidelines for qualification in pharmaceutical and food-grade installations.

Applications

• Continuous additive dosing in polymer extrusion and coating lines
• Recirculation and filtration feed in semiconductor wet benches
• Media supply in single-use bioreactors and perfusion culture systems
• Chlorine dioxide and sodium hypochlorite metering in municipal water disinfection skids
• High-flow solvent transfer in HPLC preparative systems and column cleaning protocols
• OEM integration into analytical instruments requiring pulsation-free, low-shear liquid handling

FAQ

What tubing sizes are officially supported by the YZ35-13?
The YZ35-13 is calibrated and tested for #73 and #82 tubing per the ISO 8536-4 standard; alternative sizes require occlusion recalibration and are not covered under warranty.
Can multiple YZ35-13 pump heads be synchronized on a single drive shaft?
Yes—the pump head features ISO-standard timing belt pulley mounts and axial alignment dowel pins enabling mechanically coupled, phase-synchronized operation of up to four units.
Is the PSU housing resistant to ozone or chlorine-based oxidants?
PSU exhibits excellent resistance to aqueous chlorine solutions below 5 ppm and ambient ozone; prolonged exposure to gaseous ozone >0.1 ppm or free chlorine >10 ppm is not recommended without protective shielding.
Does LongerPump provide validation documentation for pharmaceutical use?
Yes—OQ/IQ protocol templates, material traceability certificates (EN 10204 3.1), and tubing compatibility matrices are available upon request for regulated environments.
What is the maximum allowable inlet pressure when using the YZ35-13?
The pump head is designed for atmospheric or slight positive inlet pressure (≤0.2 bar); backpressure exceeding 1.5 bar requires downstream pressure regulation to prevent tubing slippage or premature fatigue.
