Product Overview
The Watson-Marlow 056.9131.00A is a precision-engineered peristaltic pump head designed for accurate, low-shear fluid transfer in demanding industrial and process environments. As a positive displacement pump head, it operates by progressively compressing a flexible tube with rotating rollers, displacing fluid through the tubing without the fluid ever contacting internal pump components. This design eliminates cross-contamination, simplifies sterilization and maintenance, and provides excellent dosing repeatability. The 056.9131.00A is a direct-fit replacement head compatible with Watson-Marlow OEM drive units, making it a reliable choice for metering, dosing, and transfer duties in critical industrial processes.
