Direct replacement for old or damaged pumps: Built with precision workmanship to serve as a reliable replacement in compatible systems, helping restore performance without extensive modification. Quiet, durable wheel frame: The wheel frame uses ball bearings for quiet operation and long service life. Includes a card slot for deviation correction and to help prevent pump damage. flow peristaltic pump: Delivers a flow rate of 500 ml/min, suitable for a variety of fluid transportation tasks. Corrosionresistant hardware: Stainless steel screws resist rust and corrosion, ensuring durability and stability of the pump assembly. Practical use scenarios: Replacing a failed pump in a laboratory fluid transfer setup to resume routine experiments with minimal downtime. Upgrading maintenancecritical systems where quiet operation and long service life are valued in continuoususe environments. Supporting smallscale liquid handling in production or processing tasks that require a steady 500 ml/min flow rate. Key attributes at a glance: function as a pump replacement, compatibility with standard peristaltic configurations, 500 ml/min flow capability, stainless steel fasteners, corrosion resistance, and a ballbearing wheel frame for smooth, quiet performance.
