Masterflex I/P High-Flow Peristaltic Pump Head (Model 77600-62)

Overview

The Masterflex® I/P High-Flow Peristaltic Pump Head (Model 77600-62) is an engineered component designed for integration into precision fluid handling systems in regulated laboratory, pilot-scale, and industrial process environments. As a key element of the Masterflex I/P series, this pump head operates on the principle of peristalsis—using rotating rollers to compress flexible tubing progressively, thereby generating positive displacement flow without internal valves or seals. Its C-frame architecture, combined with fully stainless steel (316 SS) construction of the rotor, bearings, hub, and shaft, ensures mechanical robustness, corrosion resistance, and long-term dimensional stability under continuous operation. The design supports high-torque transmission and accommodates larger-diameter tubing (e.g., Masterflex Norprene® L/S® 26, 73, and 82 series), enabling sustained flow rates up to 22 L/min depending on tubing selection and drive speed—making it suitable for applications requiring reliable, pulse-free, low-shear transfer of sensitive or abrasive fluids.

Key Features

• Stainless steel (316 SS) rotor, hub, shaft, and precision-ground roller assembly for extended service life and resistance to chemical degradation
• C-frame structural design optimized for rigidity, minimizing deflection during high-speed or high-pressure operation
• ATEX Zone 2 certification (EEx II 3G c II C T6) — compliant with EN 60079-0 and EN 60079-32-1 for use in potentially explosive atmospheres
• Interchangeable compatibility with Masterflex I/P-compatible drives (e.g., 77200-series, 77400-series) via standardized mounting interface
• Tool-free tubing loading capability when paired with appropriate I/P drive units; supports rapid maintenance cycles without recalibration
• Optimized roller geometry and dwell angle to reduce tubing fatigue and extend operational lifespan of elastomeric tubing

Sample Compatibility & Compliance

The 77600-62 pump head is validated for use with a broad range of FDA-compliant, USP Class VI-certified tubing materials—including Norprene® L/S®, PharMed® BPT, and Viton®—enabling safe handling of aqueous, organic, and mildly aggressive reagents. It meets ISO 9001 manufacturing standards and conforms to relevant sections of ASTM D1248 (for polymeric tubing evaluation) and IEC 61000-6-3 (EMC emissions). When integrated into full-system configurations, the pump head supports GLP and GMP workflows through traceable installation records and documented maintenance intervals. While the pump head itself does not carry CE marking independently, its ATEX certification and material declarations facilitate compliance with EU Machinery Directive 2006/42/EC when installed within certified host systems.

Software & Data Management

As a mechanical pump head, the 77600-62 does not incorporate embedded electronics or firmware. However, when mounted on digitally controlled Masterflex I/P drives (e.g., models with RS-232, USB, or analog 0–10 V inputs), it participates in closed-loop flow control architectures. Compatible software platforms—including Cole-Parmer’s PumpCom™ and third-party SCADA/HMI systems—enable remote parameterization of speed, direction, and run duration. Audit trails, event logging, and user-access controls may be implemented at the drive or supervisory system level in accordance with FDA 21 CFR Part 11 requirements, provided the host controller includes electronic signature functionality and secure data storage.

Applications

• Continuous feed in bioreactor perfusion systems and chromatography buffer delivery
• High-volume media transfer in cell culture and fermentation laboratories
• Chemical dosing in water treatment pilot plants and environmental monitoring stations
• Reagent dispensing in automated clinical analyzers and ELISA wash stations
• Recirculation loops in thermal stability testing rigs and HVAC commissioning setups
• Low-shear pumping of shear-sensitive suspensions (e.g., microcarriers, liposomes, polymer emulsions)

FAQ

Is the 77600-62 pump head compatible with non-Masterflex tubing?
Yes, provided the tubing’s outer diameter, wall thickness, and durometer fall within the mechanical envelope defined by the roller spacing and compression profile—however, performance validation (flow accuracy, pulsation, tubing life) must be conducted empirically.
Does this pump head require periodic recalibration?
No—peristaltic pump heads are displacement-based mechanical components with no internal sensors; calibration is performed at the drive motor level (e.g., RPM-to-flow mapping using gravimetric or volumetric verification).
Can the 77600-62 be used in sterile processing environments?
It may be deployed in cleanroom-adjacent applications if housed in an IP54-rated enclosure and paired with autoclavable or gamma-sterilizable tubing; however, the pump head itself is not designed for direct sterilization.
What is the maximum recommended operating speed for continuous duty?
When used with L/S 26 or L/S 73 tubing and driven by a 77400-series I/P drive, the manufacturer recommends ≤ 350 rpm for extended service life; higher speeds increase tubing wear and heat generation.
Are replacement rollers or bearings available as spare parts?
Yes—Cole-Parmer supplies genuine OEM replacement kits (e.g., P/N 07019-62-RK) including pre-greased 316 SS bearings, hardened roller assemblies, and alignment spacers to maintain original torque transmission characteristics.
