Masterflex peristaltic pumps provide reliable solutions for demanding fluid handling applications.

These new Masterflex B/T tubing sizes 87 and 91 are optimized to provide better performance in higher-pressure applications. Each tubing size is manufactured to extremely close tolerances that match our B/T pump heads.

Thermo Scientific Masterflex B/T: Air Powered, Fixed Speed and Pump Head Adapter Systems

Thermo Scientific Masterflex B/T Series: Analog or Digital Variable-Speed Systems

Deliver flow rates from 0.12 to 17 LPM (0.03 to 4.5 GPM). No electric power required?use where electricity is unsafe or impractical

Deliver flow rates from 0.12 to 17 LPM (0.03 to 4.5 GPM). Modular design lets you place system components where they are most convenient. Digital readout displays exact flow rate, dispense volume, copy number, or drive RPM.

Economical and simple to operate



Reversible, maintenance-free brushless motor with precise PWM control via a digital signal processor (DSP). Digital display of flow rate, dispense volume/cumulative amount per dispense, copy, and motor RPM.

Convenient three- and four-channel fixed-speed pumps come complete with pump heads, tubing, and drive. Use multiple channels to increase your flow rate, or pump different fluids simultaneously from a single drive.

Deliver flow rates from 0.12 to 17 LPM (0.3 to 4.1 GPM). Attach your own motor to meet local electrical codes, hazardous-duty requirements, washdown necessity, and your unique needs.

Brushless motor handles challenging applications with minimal maintenance. Compact drive is light enough to carry with one hand, but powerful enough to drive two pump heads.

Deliver flow rates from 0.12 to 17 LPM (0.03 to 4.5 GPM) with Masterflex® I/P® pump heads. Convenient modular style; mount washdown controller and motor in separate locations

Interface these brushless digital drives to a computer for automated lab and process applications.

Ideal for very low-flow applications. Deliver flow rates from 0.06 to 348 mL/min (0.001 to 5.5 GPH)

Masterflex P/S process peristaltic pump Digital readout. IP66 and NEMA 4X rated for washdown. Sealed, 316 stainless steel housing. Maintenance-free brushless motor with PWM speed control.

Deliver flow rates from 0.06 to 3400 mL/min (up to 54 GPH) with Masterflex® P/S® pump heads. Motor and controller in one convenient package.

Transfer, dispense, and meter in lab, process and washdown environments.



Thermo Scientific Masterflex P/S Standard Digital Pump Systems combine digital control with peristaltic pump technology to provide high-accuracy, maintenance and worry free performance to your chemical feed applications.

Deliver flow rates from 3.6 to 3400 mL/min (up to 54 GPH). Ideal for hazardous-duty locations.

Wide flow ranges; durable, powerful motors; and easy-to-read digital displays

Deliver flow rates from 0.6 to 2500 mL/min (up to 40 GPH). Ideal for areas that require special electrical precautions.

Designed for accurate metering and low maintenance operations. Feature a IP56-rated wall-mount controller and full-featured remote control capabilities.

For wet or hostile environments. Deliver flow rates from 0.36 to 3400 mL/min (up to 54 GPH).
