Masterflex L/S Pneumatic-Driven Variable-Speed Peristaltic Pump Model 07569-00

Overview

The Masterflex L/S Pneumatic-Driven Variable-Speed Peristaltic Pump Model 07569-00 is an industrial-grade, intrinsically safe fluid transfer solution engineered for laboratories, pilot plants, and process environments where electrical hazards, explosive atmospheres, or unreliable power infrastructure preclude the use of electrically driven pumps. Operating on clean, dry compressed air, this pump employs classic peristaltic displacement mechanics—where rotating rollers compress elastomeric tubing against a rigid housing—to deliver pulse-free, non-contaminating, and sealless fluid handling. Its 3/4 hp (250 W equivalent) air motor delivers robust torque across the full 60–600 rpm speed range, enabling precise volumetric control without contact between the drive mechanism and the fluid path. Designed in strict compliance with EU Machinery Directive 2006/42/EC, it carries EEx II 3 G c IIC T6 certification for safe operation in ATEX Zone 2 hazardous areas—making it suitable for solvent-based, flammable, or reactive chemical handling under GLP, GMP, or ISO 9001-aligned workflows.

Key Features

• Pneumatic drive eliminates spark risk and thermal load—ideal for Class I Division 2 / ATEX Zone 2 environments requiring intrinsic safety.
• IP44-rated steel enclosure with protective coating provides resistance to water splashes and mechanical impact in demanding lab or industrial settings.
• Integrated air regulation system includes a 5 µm particulate filter, 1/4″ NPT(F) regulator, automatic lubricator, 0–30 psi pressure gauge, and noise-dampening muffler—ensuring consistent airflow and extended motor life.
• ±10% speed repeatability supports reproducible dosing and continuous flow applications across diverse tubing sizes and viscosities.
• Modular L/S platform compatibility: accepts up to two interchangeable pump heads—including Easy-Load II, High-Performance, Cartridge, Multi-Channel, PTFE Tubing, and PTFE Diaphragm variants—enabling rapid reconfiguration for single- or multi-stream protocols.
• No electrical input required; operates solely on regulated compressed air (20–100 psi / 1.4–6.9 bar at 3–25 CFM), reducing installation complexity and eliminating grounding concerns beyond static dissipation protocols.

Sample Compatibility & Compliance

This pump accommodates a wide range of chemically resistant tubing materials—including silicone, Viton®, Tygon® B-44-4X, PharMed® BPT, and PTFE-lined options—supporting aqueous, organic, acidic, basic, and mildly abrasive solutions up to 3400 mL/min. Its design conforms to key international safety and performance standards: ATEX Directive 2014/34/EU (Category 3G, Equipment Group II, Gas Group IIC, Temperature Class T6); IEC 60079-0 and IEC 60079-15 for non-sparking equipment; and EN 60204-1 for control circuit safety. The IP44 rating meets IEC 60529 requirements for protection against solid objects >1 mm and water splashing from any direction. While not inherently FDA-compliant as a standalone unit, it supports USP Class VI-certified tubing assemblies when validated per user-defined SOPs and aligned with 21 CFR Part 11 data integrity expectations via external logging systems.

Software & Data Management

The Model 07569-00 is an analog-controlled device with no embedded firmware, touchscreen, or digital interface—ensuring long-term operational stability, immunity to electromagnetic interference, and simplified validation in regulated environments. Speed is adjusted manually via the integrated air pressure regulator, and flow rate is inferred from calibrated tubing inner diameter, rotational speed, and fluid rheology. For traceable operation, users may integrate third-party analog-to-digital signal converters (e.g., 4–20 mA or 0–10 V output modules) with SCADA, LabVIEW, or LIMS platforms to record speed setpoints, runtime, and cumulative volume. Audit trails, electronic signatures, and change control are maintained externally in accordance with ALCOA+ principles and FDA 21 CFR Part 11 Annex 11 requirements when paired with compliant software infrastructure.

Applications

• Safe transfer of flammable solvents (e.g., acetone, ethanol, hexane) in explosion-proof fume hoods or solvent recovery systems.
• Continuous feeding of catalysts or reagents into jacketed reactors where electrical isolation is mandated.
• High-purity pharmaceutical intermediate dosing using PTFE-lined tubing and sterile-filtered air supply.
• Environmental sample preparation—e.g., automated dilution or extraction workflows in EPA Method-compliant labs.
• Food & beverage R&D involving viscous or particulate-laden fluids (e.g., fruit pulps, dairy emulsions) where sanitary tubing changeover must be rapid and tool-free.
• Academic research in electrochemistry or battery material synthesis requiring inert-atmosphere glovebox integration via feedthrough-compatible air lines.

FAQ

Does this pump require electrical grounding?
No electrical power is consumed; however, proper static grounding of the pump frame and associated metal components is mandatory when operating in flammable environments to prevent electrostatic discharge.
What compressed air quality is required?
Air must be clean, dry, and oil-free per ISO 8573-1 Class 3.0.1 (maximum 5 µm particles, dew point ≤ −20 °C, oil content ≤ 0.01 mg/m³) to protect the air motor and ensure regulator longevity.
Can it be used with conductive or antistatic tubing?
Yes—tubing with surface resistivity < 10⁶ Ω/sq (e.g., Tygon® Antistat, Cole-Parmer Conductive Silicone) is compatible and recommended for static-sensitive applications.
Is calibration traceable to NIST standards?
The pump itself is not a measuring instrument; volumetric accuracy depends on tubing geometry, roller compression, and speed calibration. Users must perform in-house flow verification using gravimetric or timed-collection methods traceable to NIST-traceable mass or time standards.
What maintenance intervals are recommended?
Under typical lab use, inspect air filter monthly, replace lubricator oil every 6 months, and verify regulator seal integrity annually. No scheduled motor servicing is required due to the absence of brushes, windings, or bearings subject to electrical wear.
