Masterflex I/P Fixed-Speed Peristaltic Pump (No Display)

Overview

The Masterflex I/P Fixed-Speed Peristaltic Pump (Model 07588-65) is an industrial-grade, single-channel peristaltic pumping system engineered for reliable, contamination-free fluid transfer in laboratory, pilot-scale, and light industrial applications. Based on the proven roller-compression principle of peristalsis, the pump operates by sequentially compressing flexible tubing against a rigid housing using rotating rollers—eliminating direct contact between the drive mechanism and the fluid path. This design ensures complete fluid isolation, making it ideal for sterile, shear-sensitive, or highly reactive media. Designed and manufactured in the United States under strict quality control protocols, the I/P series complies with ISO 9001:2000 and carries cULus and CE markings, affirming its suitability for use in regulated environments across North America and the EU. Its fixed-speed architecture delivers consistent rotational output without digital feedback or speed adjustment, prioritizing mechanical robustness, long-term repeatability, and low-maintenance operation.

Key Features

• IP55-rated enclosure for protection against dust ingress and low-pressure water jets—enabling safe operation in wet or washdown-prone lab environments.
• Direct-drive, brushless AC motor with thermal overload protection and stable torque delivery across voltage fluctuations (190–260 V AC, 50 Hz).
• Interchangeable pump head configurations: supports dual-, triple-, and quad-head setups via standardized mounting interfaces—enabling parallel processing, multi-stream blending, or flow amplification via Y-branch manifolds.
• Easy-Load® pump heads (e.g., 77601-10) allow rapid, tool-free tubing loading and alignment—reducing setup time and minimizing operator-induced tension errors.
• Thick-wall tubing compatibility (#70, #88, #89) enables effective handling of viscous fluids (up to ~50,000 cP) while maintaining predictable flow profiles and extended tube life.
• No display or electronic controls—minimizes electromagnetic interference (EMI) risks and eliminates firmware-related failure modes, enhancing operational stability in electromagnetically sensitive instrumentation suites.

Sample Compatibility & Compliance

The I/P pump is inherently compatible with a broad spectrum of chemically resistant, USP Class VI–certified, and FDA-compliant tubing materials—including platinum-cured silicone (biopharmaceutical grade), C-Flex®, Tygon® LFL (long-life fluoropolymer), Pharmapure®, Norprene® A-60-F (food-grade), and Chem-Durance® (high-concentration acid/base resistant). Tubing selection directly governs chemical compatibility, pressure tolerance, and particulate generation—users must consult material safety data sheets (MSDS) and compatibility charts prior to deployment. The system meets requirements for GLP-aligned workflows where audit trails are not mandated; however, when integrated into GMP or FDA 21 CFR Part 11–governed processes, external data logging (e.g., via PLC or SCADA) is required to satisfy electronic record integrity standards. All configurations comply with IEC 61000-6-2 (immunity) and IEC 61000-6-4 (emissions) for laboratory electromagnetic environments.

Software & Data Management

This model operates as a stand-alone, analog-controlled device with no embedded microprocessor, touchscreen interface, or onboard memory. Consequently, it does not support USB, RS-232, or Ethernet connectivity, nor does it generate digital logs, timestamps, or calibration histories. For traceable operation in regulated settings, integration with external programmable logic controllers (PLCs), data acquisition systems (DAQ), or laboratory information management systems (LIMS) is recommended. Flow rate verification must be performed manually using calibrated volumetric flasks or certified flow meters—consistent with ASTM D3417 and ISO 8504-2 gravimetric validation practices. Documentation packages—including Declaration of Conformity, electrical schematics, and mechanical drawings—are available upon request for IQ/OQ protocol development.

Applications

• Continuous reagent dosing in analytical chemistry workflows (e.g., ICP-OES sample introduction, titration burette filling).
• Media perfusion in cell culture bioreactors and hollow-fiber systems requiring pulseless, low-shear delivery.
• Recirculation loops for inline filtration, pH adjustment, or temperature equilibration in closed-loop process tanks.
• High-purity solvent transfer in HPLC mobile phase preparation and column cleaning protocols.
• Food & beverage R&D—viscous ingredient metering (e.g., syrups, emulsions, dairy concentrates) under sanitary conditions.
• Environmental testing labs—acid digestion effluent transfer and leachate sampling where metal-free fluid paths are critical.

FAQ

Does this pump support variable speed control?
No. The Masterflex I/P series is strictly fixed-speed. Speed variants (e.g., 83 rpm, 100 rpm, 150 rpm) are hardware-defined and require model-specific motor assemblies—not software-adjustable.
Can I use standard silicone tubing with this pump?
Yes—but only with appropriate wall thickness and durometer. Standard thin-wall silicone is not rated for continuous high-pressure or high-cycle operation; Masterflex recommends platinum-cured or reinforced biopharmaceutical grades (e.g., BioPharma Platinum) for >1,000-hour service life.
Is the pump suitable for sterile applications?
It is fluid-path sterile capable when paired with gamma-irradiated, pre-sterilized tubing (e.g., Tygon® S-50-HL or Pharmapure®) and operated within validated SOPs—but the pump housing itself is not autoclavable or SIP-compatible.
What maintenance is required?
Annual inspection of roller wear, spring tension, and bearing play is advised. Tubing replacement intervals depend on flow rate, pressure, and chemical exposure—typically every 100–500 hours for standard silicone, up to 2,000+ hours for Tygon® LFL or C-Flex® under moderate conditions.
Can multiple pump heads be synchronized?
Yes—mechanically coupled multi-head configurations (e.g., 07588-87, 07588-97) ensure identical rotational phase and speed across all channels, enabling precise proportional blending without electronic synchronization circuitry.
