Cole-Parmer Masterflex L/S Model 7554-90 Variable-Speed Pump Drive for Bioprocessing
Product Description
The Cole-Parmer Masterflex L/S Model 7554-90 Pump Drive is a variable-speed pump controller designed for precise fluid flow management in biotechnology, molecular diagnostics, and bioprocessing workflows. It features a 1/20-horsepower unidirectional (counterclockwise) motor with soft start functionality and back EMF for accurate ±5% speed control, essential for consistent peristaltic pumping applications.
Key technical specifications include:
- Separate single-turn speed control with an on/off switch and green power indicator, enabling maintenance of speed settings during power cycling.
- Robust, stackable painted steel housing, rated IP22 for protection against vertically falling water, suitable for laboratory and clinical environments.
- Compatible with standard power supplies: UL and cUL listed for 115 VAC (with U.S. plug) and CE marked for 230 VAC models featuring IEC 320/CEE22 sockets, supporting global research settings.
- Includes a 6-foot (1.8-meter) line cord tailored to regional electrical standards, ensuring convenient installation.
This pump drive is widely adopted in biomedical engineering, synthetic biology, and live-cell imaging laboratories where precise flow rate control is critical. Its versatile flow range and reliable speed modulation make it a popular choice in molecular cloning workflows and biopharmaceutical production pipelines, supporting demanding bioprocessing and gene editing applications.
