Blue-White A3F26-NH High-Pressure Peristaltic Pump

Overview

The Blue-White A3F26-NH High-Pressure Peristaltic Pump is an engineered solution for precise, pulse-free, and contamination-free fluid transfer in demanding laboratory, pilot-scale, and industrial process environments. Operating on the principle of peristalsis—where rollers compress a flexible tube against a curved housing to generate positive displacement—the A3F26-NH delivers exceptional pressure capability (up to 8.6 bar) while maintaining volumetric accuracy and long-term stability. Its design eliminates valves, seals, and wetted metal components, making it inherently suitable for shear-sensitive, abrasive, viscous (up to 12,000 cP), or chemically aggressive fluids. Unlike centrifugal or diaphragm pumps, this unit ensures zero backflow and minimal pulsation, critical for applications requiring consistent dosing, calibration standards delivery, or integration into closed-loop control systems.

Key Features

• High-pressure capability (8.6 bar) with stable flow across the full range (0.4–1097 mL/min), enabling use in pressurized reactor feed, inline filtration, and high-backpressure chromatography systems.
• Intelligent leak detection: Integrated pump head sensor triggers immediate shutdown upon tubing rupture or leakage, preventing sample loss, equipment damage, and safety hazards.
• Fine-grained speed control: Adjustable from 0.05% to 99% of maximum speed, with resolution of 0.001% below 1%, 0.01% between 1–10%, and 0.1% above 10%—supporting ultra-low-flow applications such as microfluidic priming or reagent metering.
• Speed accuracy of ±0.5% full scale and repeatability of ±0.5%, verified under ISO 5167-compliant flow calibration conditions, ensuring traceable performance for GLP and GMP workflows.
• IP66-rated enclosure allows direct washdown with water or mild detergents—ideal for cleanroom-adjacent labs, bioprocessing suites, and food-grade environments.
• Bidirectional operation with programmable direction reversal supports purge cycles, backflush protocols, and dual-path sampling configurations.
• Tubing life monitoring algorithm estimates remaining operational hours based on cumulative compression cycles and runtime, providing predictive maintenance alerts via front-panel display.
• Configurable analog interface (4–20 mA / 0–10 V) enables seamless integration with PLCs, SCADA systems, or LIMS platforms for centralized process supervision and audit-trail generation.

Sample Compatibility & Compliance

The A3F26-NH is compatible with FDA-compliant Norprene® tubing—a synthetic elastomer exhibiting broad chemical resistance (including strong acids, bases, oxidizers, and organic solvents), low gas permeability, and NSF/ANSI 51 certification for food contact. Its non-metallic fluid path eliminates ion leaching, making it suitable for ultrapure water systems, pharmaceutical buffer preparation, and analytical sample introduction. The pump meets UL 61010-1 (Safety Requirements for Electrical Equipment for Measurement, Control, and Laboratory Use) and conforms to CE marking directives for electromagnetic compatibility (EMC Directive 2014/30/EU) and low-voltage safety (LVD Directive 2014/35/EU). While not intrinsically rated for Class I Div 1 hazardous locations, its robust insulation and grounding design support use in non-explosive but corrosive or high-humidity environments typical of chemical synthesis labs and wastewater treatment pilot plants.

Software & Data Management

The A3F26-NH operates as a standalone instrument with local keypad and LED display for real-time speed, direction, and status monitoring. For networked deployment, optional RS-485 Modbus RTU communication (via add-on module) enables remote parameter setting, runtime logging, and event-triggered data capture—including leak events, speed deviations, and power interruptions. When integrated into validated environments, the pump’s analog output signals can be recorded by compliant data acquisition systems supporting 21 CFR Part 11 requirements, including electronic signatures, audit trails, and user access controls. Firmware updates are performed via secure USB interface with version rollback capability, ensuring continuity during regulatory inspections.

Applications

• Continuous feeding of catalysts or inhibitors into high-pressure polymerization reactors.
• Accurate delivery of calibration standards and QC samples to ICP-MS, HPLC, and IC systems.
• Controlled addition of pH adjusters or coagulants in membrane filtration pilot studies.
• Low-shear transfer of cell culture media, vaccines, or protein solutions in biomanufacturing R&D.
• Automated cleaning-in-place (CIP) and sterilization-in-place (SIP) fluid circulation in modular skids.
• Environmental testing: extraction and dosing of contaminated soil leachates or industrial effluents for toxicity assays.

FAQ

What tubing sizes are compatible with the A3F26-NH pump head?
The A3F26-NH is configured for standard Norprene® tubing with inner diameters of 0.031″ to 0.250″ (0.8–6.4 mm), optimized for the specified flow range and pressure rating. Custom tubing calibrations may be performed using Blue-White’s FlowCal software.
Does the pump support external start/stop and speed modulation?
Yes—via isolated 4–20 mA or 0–10 V analog inputs, allowing dynamic speed adjustment synchronized with upstream/downstream process variables such as pressure, pH, or conductivity.
Is the pump suitable for sterile applications?
While the pump itself is not autoclavable, Norprene® tubing is gamma-irradiation compatible (up to 50 kGy), and the IP66 enclosure permits aseptic wipe-down. For Grade A environments, it is deployed outside the isolator with sterile tubing routed through a pass-through port.
How is calibration traceability maintained?
Each unit ships with a factory calibration certificate referencing NIST-traceable flow standards. End users may perform periodic verification using gravimetric or timed-volume methods per ASTM D3236 or ISO 5167 Annex C guidelines.
Can multiple A3F26-NH units be synchronized?
Yes—using Modbus RTU daisy-chaining or master-slave configuration over RS-485, enabling coordinated multi-pump operations such as gradient elution or parallel reactor feeding.
