TC2500 Quaternary Diaphragm Pump
Smart TC Series four-piston diaphragm pump for sanitary and biopharmaceutical applications
Overview
The TC2500 Smart Quaternary Diaphragm Pump is designed for sanitary fluid transfer applications that require stable flow, low pulsation, low shear, and easy cleaning. It is well suited for production-scale biopharmaceutical process systems where reliable fluid transfer, product integrity, and hygienic design are critical.
With a flow range of 0.4–40 L/min and a maximum operating pressure of 6 bar, the TC2500 provides stable and efficient pumping performance for sanitary production processes. Its wetted materials are selected for hygienic compatibility, and the pump structure is designed to support clean operation, simple maintenance, and dependable long-term operation.

Speed-Flow Characteristics
The figure below shows the speed-flow characteristic curves of the TC2500 pump head at different operating pressures, using purified water at room temperature as the test medium.
The relationship between speed and flow is essentially linear, demonstrating stable and predictable flow performance across the operating range. The adjustable speed range is 10–1000 rpm, and the maximum flow rate can exceed 40 L/min under appropriate operating conditions.
The linear relationship between speed and flow enables stable, predictable, and controllable fluid transfer performance across a wide operating range.
