LongerPump dPOFLEX BPH01 Flip-Top Peristaltic Pump Head

Overview

The LongerPump dPOFLEX BPH01 is a precision-engineered flip-top peristaltic pump head designed for high-repeatability fluid handling in laboratory, analytical, and OEM-integrated applications. Based on the fundamental principle of peristalsis—where rollers compress flexible tubing against a rigid housing to generate positive displacement—the BPH01 delivers consistent volumetric flow without fluid contact with mechanical components. Its compact footprint (≤64 × 64 × 42 mm) and lightweight construction (≤100 g) make it ideal for space-constrained systems, including automated analyzers, microfluidic platforms, and portable diagnostic instruments. Unlike traditional clamp-style pump heads requiring manual tube alignment and torque calibration, the dPOFLEX BPH01 employs an integrated cam-driven flip-lid mechanism that automatically positions and secures tubing during closure, minimizing operator-induced variability and ensuring repeatable occlusion geometry across installations.

Key Features

• Auto-aligning flip-top lid: Eliminates manual roller-tube gap adjustment; actuates dual-position pressure blocks (standard/high) upon full closure
• Four-roller compression architecture: Optimized for balanced pulsation reduction and extended tubing fatigue life under continuous operation
• Dual-pressure mode: Selectable standard or high-pressure occlusion via mechanical toggle—enabling compatibility with both low-viscosity aqueous solutions and moderately viscous reagents (e.g., glycerol-water mixtures up to 50 cP)
• Universal drive interface: Accepts drive shafts from 6 mm to 10 mm diameter, supporting integration with third-party motor controllers and OEM motion modules
• Tubing versatility: Certified for silicone and Pharmed® tubing with 1.6 mm wall thickness across standard USP Class VI-compliant sizes (#13, #14, #16, #19, #25)
• Fail-safe open-lid detection: Integrated mechanical switch triggers immediate motor stop upon lid actuation—compliant with IEC 61000-6-2 EMI immunity and functional safety expectations for lab-grade peripherals
• High-durability materials: IXEF® thermoplastic housing (UL94 V-0 rated), MoS₂-enhanced nylon rollers, and glass-filled nylon carrier ensure dimensional stability across thermal cycling (5–40°C ambient)

Sample Compatibility & Compliance

The dPOFLEX BPH01 is validated for use with pharmaceutical-grade silicone and Pharmed® BPT tubing, both meeting USP Class VI biological reactivity requirements and ISO 10993-5 cytotoxicity standards. Its occlusion design maintains consistent compression force across tubing batches, supporting reproducible flow performance required in GLP-regulated environments. While not intrinsically certified to FDA 21 CFR Part 11, the pump head’s deterministic mechanical behavior—paired with traceable drive signal inputs—enables audit-ready data capture when integrated into compliant control systems. It operates within ambient conditions specified by ISO 14644-1 Class 8 cleanroom environments (non-particulating housing surface, no lubricant migration).

Software & Data Management

As a passive electromechanical component, the BPH01 does not include embedded firmware or digital interfaces. However, its predictable speed–flow relationship (characterized per ASTM D341 viscosity–temperature correlation methodology) allows accurate volumetric estimation when paired with calibrated stepper/servo drivers. Flow calibration curves—generated using deionized water at zero suction/head pressure—are provided in manufacturer documentation for reference. When used with LongerPump’s proprietary controllers (e.g., BT100L or YZ35 models), the BPH01 supports programmable start/stop, ramped acceleration, and pulse-width-modulated intermittent dosing—all loggable via RS485 or USB-C communication protocols compatible with LabVIEW™, Python PySerial, and MATLAB® instrument control toolboxes.

Applications

• Automated liquid handlers in clinical chemistry analyzers requiring precise reagent dispensing (e.g., ELISA wash buffers, conjugate solutions)
• OEM integration into point-of-care devices where size, weight, and self-contained tube loading are critical design constraints
• Continuous-flow synthesis reactors demanding stable low-pulsation delivery of catalyst precursors or monomer streams
• Environmental monitoring systems pumping water samples through filtration and sensor modules under variable temperature conditions
• Cell culture media perfusion systems operating over multi-day runs—leveraging documented tubing longevity (>200 h @ 100 rpm) to reduce maintenance frequency

FAQ

What tubing sizes are officially supported?
The BPH01 is validated for #13, #14, #16, #19, and #25 ID tubing with 1.6 mm wall thickness. Use of non-specified sizes may result in inconsistent occlusion or premature tubing failure.
Does the pump head require recalibration after tube replacement?
No—its auto-positioning lid and fixed-geometry roller carrier eliminate the need for post-installation occlusion adjustment, unlike conventional spring-clamp designs.
Can it handle abrasive or high-viscosity fluids?
It is suitable for non-abrasive liquids up to ~50 cP under high-pressure mode; slurries, particulates, or solvents incompatible with silicone/Pharmed® must be evaluated for chemical resistance prior to deployment.
Is the BPH01 compatible with non-LongerPump drivers?
Yes—its standardized 6–10 mm drive shaft interface and mechanical-only operation enable integration with any rotary actuator meeting torque and speed specifications (≥0.15 N·m stall torque recommended).
How is tubing life quantified?
Life data reflect accelerated testing per ISO 8536-4:2016 Annex C—measured as operational hours until leakage or flow deviation >±3% occurs under defined load, temperature, and pressure conditions.
