TC018 Quaternary Diaphragm Pump
Smart TC Series four-piston diaphragm pump for sanitary and biopharmaceutical applications
Overview
The TC018 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 laboratory systems, analytical instruments, and other hygienic process environments where precise flow control, product purity, and cleanability are critical.
With a flow range of 0.005–0.3 L/min and a maximum operating pressure of 10 bar, the TC018 provides precise and consistent pumping performance in compact sanitary systems. Its wetted materials are selected for hygienic compatibility, and the pump structure is designed to support clean operation, simple maintenance, and reliable long-term use.

Speed-Flow Characteristics
The figure below shows the speed-flow characteristic curves of the TC018 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 20–2000 rpm, and the maximum flow rate can exceed 0.3 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.
