Masterflex L/S Pneumatic Peristaltic Pump Model 07569-00

Overview

The Masterflex® L/S Pneumatic Peristaltic Pump Model 07569-00 is an industrial-grade, air-driven peristaltic pump engineered for safe, precise, and maintenance-efficient fluid transfer in hazardous or electrically restricted environments. Designed to operate without electrical power, it eliminates spark risks during handling of flammable solvents, aggressive chemicals, inks, pharmaceutical intermediates, and other Class I/II/III hazardous substances. Its operation relies on positive displacement via occlusion—where a rotating roller train compresses elastomeric tubing against a rigid housing, generating repeatable volumetric flow proportional to rotational speed and tubing geometry. This principle ensures inherent fluid isolation, zero contamination risk, and no need for valves, seals, or dynamic gaskets—making it ideal for sterile, high-purity, or corrosion-sensitive applications across R&D labs, pilot plants, and regulated manufacturing settings.

Key Features

• Air-powered 0.75 hp (250 W) variable-speed reversible motor with low thermal output—operating at one-third the heat generation of comparable electric drives.
• Rugged powder-coated steel frame rated IP44 for protection against water splashes and particulate ingress in laboratory and light industrial environments.
• Wide speed range of 60–600 rpm with ±10% speed accuracy, enabling fine-tuned control over low-flow precision dosing (down to 3.6 mL/min) and high-throughput transfer (up to 3400 mL/min with 36# tubing and high-pressure pump heads).
• Integrated pneumatic accessories: 5 µm inline air filter, pressure regulator with 1/4″ NPT(F) port, automatic lubricator, 0–30 psi analog pressure gauge, and noise-dampening muffler—ensuring clean, stable, and quiet actuation.
• Modular compatibility with up to two pump heads simultaneously; supports Y-branch manifold configuration for doubled flow capacity without flow imbalance.
• ATEX-certified for Zone 2 (EEx II 3Gc IIC T6) operation—validated for use in potentially explosive atmospheres containing gases, vapors, or mists where ignition sources must be rigorously controlled.

Sample Compatibility & Compliance

The 07569-00 accommodates a broad spectrum of tubing materials—including silicone (standard, platinum-cured, biopharmaceutical grades), fluoropolymer (Viton®, C-Flex®, Chem-Durance®), thermoplastic elastomers (Pharmed®, Norprene®, Tygon® series), and ultra-pure formulations (Tygon 2475, Pharmapure®). Tubing selection directly governs chemical resistance, pressure tolerance, particle shedding, and regulatory compliance. The system supports tubing IDs from 0.8 mm to 9.6 mm (e.g., #13 to #36), enabling adaptation to viscosity ranges from aqueous buffers to viscous polymer solutions. Regulatory alignment includes adherence to ISO 9001:2000 quality management systems, CE marking per EU Machinery Directive 2006/42/EC, and full traceability documentation supporting GLP/GMP audit requirements. While not inherently FDA 21 CFR Part 11 compliant, its analog speed control and mechanical design facilitate integration into validated workflows when paired with external electronic logging systems.

Software & Data Management

As a purely pneumatic, analog-controlled instrument, the 07569-00 does not incorporate embedded firmware, digital interfaces, or onboard data storage. Its operational parameters—speed, air pressure, and flow—are set manually via mechanical regulators and calibrated dials. This architecture ensures electromagnetic immunity, long-term reliability under continuous duty cycles, and freedom from software obsolescence. For laboratories requiring electronic monitoring or audit trails, the pump is compatible with third-party flow meters (e.g., Coriolis or ultrasonic sensors), programmable logic controllers (PLCs), or SCADA systems via analog 4–20 mA or 0–10 V signal conditioning modules. All accessories—including Easy-Load II and ATEX-rated pump heads—ship with full dimensional drawings, material certifications (USP Class VI, FDA 21 CFR 177.2600, EC 1935/2004), and RoHS/REACH declarations.

Applications

This pump serves critical roles in environments where electrical safety, fluid purity, or chemical compatibility are non-negotiable. Typical deployments include: solvent delivery in explosion-proof fume hoods; metered reagent addition in automated synthesis reactors; sterile media transfer in bioprocessing skids; ink circulation in precision printing R&D; acid/base dosing in wastewater neutralization loops; and peristaltic sampling in continuous emission monitoring systems (CEMS). Its dual-head capability supports parallel feed lines for multi-component blending or redundant backup configurations. In pharmaceutical manufacturing, it is frequently specified for buffer preparation, chromatography mobile phase delivery, and fill-finish auxiliary pumping—provided tubing and pump head selections meet relevant USP , , and extractables/leachables criteria.

FAQ

What tubing sizes are supported by the Model 07569-00?
It accepts standard Masterflex L/S tubing sizes #13 through #36, corresponding to inner diameters from 0.8 mm to 9.6 mm. Flow performance varies with wall thickness, material durometer, and pump head type—reference the official Masterflex tubing selection guide for pressure and life-cycle specifications.
Can this pump be used in a Class 1 Division 1 environment?
No. It is certified for ATEX Zone 2 (equivalent to NEC Class I, Division 2), meaning it is suitable only where hazardous concentrations are expected only under abnormal conditions—not continuous or frequent presence of ignitable mixtures.
Is the drive unit compatible with both single- and dual-head configurations?
Yes. The chassis and motor assembly support mounting of one or two L/S pump heads, with independent roller trains. When using identical heads and tubing, total flow scales linearly using a Y-connector—no recalibration is required.
What maintenance intervals are recommended for the pneumatic motor?
With proper air filtration (5 µm) and regular lubrication via the integrated oiler, the motor requires no scheduled overhaul for ≥10,000 hours of operation. Annual inspection of O-rings, regulator diaphragms, and muffler elements is advised.
Does Cole-Parmer provide validation documentation for GMP use?
Yes—upon request, Cole-Parmer supplies IQ/OQ protocol templates, material traceability reports, and ATEX certificate copies. Final validation remains the responsibility of the end user’s qualified personnel per their internal SOPs.
