Masterflex I/P Pneumatic Peristaltic Pump Model 77980-00

Overview

The Masterflex I/P Pneumatic Peristaltic Pump Model 77980-00 is an intrinsically safe, air-driven peristaltic pumping system engineered for precise, contamination-free fluid transfer in high-risk industrial and laboratory environments. Unlike electrically actuated pumps, this model eliminates ignition sources by operating exclusively on compressed air—making it suitable for use in hazardous locations where flammable vapors, combustible dusts, or explosive atmospheres are present. Its design conforms to the fundamental principles of peristaltic displacement: a rotating roller assembly compresses flexible tubing against a curved housing, generating positive displacement without internal valves, seals, or wetted metal components. This architecture ensures zero cross-contamination, full chemical compatibility with selected elastomers, and maintenance of sterile or ultra-pure process integrity. The pump is certified to ATEX Zone 2 (EEx II 3Gc IIC T6) and NEC Class 1, Division 2 standards—enabling deployment in pharmaceutical cleanrooms, chemical synthesis labs, paint & ink formulation facilities, and solvent-handling production lines where electrical spark hazards must be rigorously controlled.

Key Features

• Intrinsically safe pneumatic drive eliminates electrical hazards—ideal for Class I, Division 2 and ATEX Zone 2 classified areas.
• IP34-rated enclosure provides protection against vertically falling water and solid objects ≥2.5 mm—suitable for semi-industrial lab and pilot-plant settings.
• Adjustable air supply (1.4–6.9 bar) enables fine-tuned speed control across 100–650 rpm, delivering repeatable flow rates with ±10% accuracy under stable pressure conditions.
• Modular Easy-Load ATEX-certified pump head (77601-10) allows rapid, tool-free tubing installation and replacement—reducing downtime and operator exposure during maintenance.
• Integrated air conditioning package includes a 5 µm particulate filter, automatic oil-lubricator, analog 0–30 psi pressure gauge, and acoustic silencer—ensuring consistent pneumatic performance and extended actuator life.
• Dual-head configuration support enables parallel processing (e.g., simultaneous reagent addition or multi-stream blending) or flow doubling via Y-connector—without requiring separate controllers or power supplies.

Sample Compatibility & Compliance

The 77980-00 accommodates a broad spectrum of chemically aggressive, viscous, or shear-sensitive fluids—including organic solvents (acetone, THF, DMF), aqueous acids/bases, UV-curable inks, polymer emulsions, and biopharmaceutical buffers—provided compatible tubing is selected. Recommended tubing materials include Masterflex Platinum-Cured Silicone (USP Class VI, ISO 10993 compliant), Saint-Gobain SPX50 silicone, and C-Flex® thermoplastic elastomer—all validated for low extractables and high flex-life. Tubing sizes (ID 6.4–16.0 mm) are matched to application-specific flow requirements and pressure drop constraints. Regulatory alignment includes CE marking, compliance with ISO 9001:2000 quality management systems, and adherence to IEC 60079-0/-15 for non-incendive equipment. While not FDA 21 CFR Part 11–validated out-of-the-box, audit-ready operation is achievable when integrated into validated processes with documented calibration, preventive maintenance logs, and change control procedures.

Software & Data Management

As a purely pneumatic, analog-controlled device, the 77980-00 does not incorporate digital firmware, embedded software, or data logging capabilities. Flow rate is mechanically regulated via air pressure and manual speed adjustment—supporting robust, deterministic operation in environments where electromagnetic interference (EMI), cybersecurity risk, or software validation overhead must be avoided. For traceability, users may pair the pump with external flow meters (e.g., Coriolis or thermal mass flow sensors) and record operational parameters (inlet pressure, RPM estimate, tubing ID, runtime) in paper-based or electronic batch records aligned with GLP or GMP documentation practices. Calibration verification is performed using gravimetric or volumetric methods per ASTM D3427 or ISO 5667-14 guidelines.

Applications

• Transfer of flammable solvents (e.g., ethanol, hexane) in explosion-proof coating or adhesive manufacturing lines.
• Accurate metering of corrosive reagents (e.g., concentrated HCl, NaOH) in continuous-flow chemistry reactors.
• Dispensing UV-curable inks in printed electronics fabrication where static discharge must be eliminated.
• Feeding shear-thinning polymer solutions into extrusion or electrospinning systems without degradation.
• Controlled delivery of cell culture media or buffer solutions in cGMP-compliant bioprocessing skids with hazardous area zoning.

FAQ

Can the 77980-00 be used in Zone 1 hazardous areas?

No—this model is certified only for Zone 2 (gas) and Division 2 environments. Zone 1 requires higher protection levels (e.g., flameproof enclosures or increased safety), which this pneumatic design does not provide.
Is tubing replacement validated per USP /?

Tubing material certifications (e.g., platinum-cured silicone) are supplied by manufacturers; end-user validation of extractables and leachables per USP chapters remains the responsibility of the process owner.
What maintenance intervals are recommended for the air filtration system?

The 5 µm filter element should be inspected weekly and replaced every 3–6 months depending on ambient air quality; lubricator oil level must be checked before each shift.
Does dual-head operation affect flow accuracy?

When identical tubing and identical air supply conditions are maintained across both heads, flow deviation remains within ±10% of setpoint—consistent with single-head performance specifications.
Can this pump handle abrasive slurries?

Not recommended—peristaltic action relies on elastic deformation of smooth-walled tubing; suspended solids >50 µm or high-abrasion particles accelerate tubing fatigue and reduce service life.
