TC1200 Four-Piston Diaphragm Pump
TC Series four-piston diaphragm pump for sanitary and biopharmaceutical applications
Overview
The TC1200 Four-Piston Diaphragm Pump is designed for sanitary fluid transfer applications requiring stable flow, low pulsation, and low shear, with a hygienic design supporting effective cleaning. It is well suited for pilot-scale and small production process systems where process consistency, product purity, and hygienic operation are essential.
With a flow range of 0.2–20 L/min and a maximum operating pressure of 6 bar, the TC1200 provides stable and efficient pumping performance in sanitary process environments. 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.
The TC1200 can be configured either as an integrated TC-S smart pump system for laboratory and process development use, or as a pump head for integration into externally controlled process systems. This allows the same pump model to be used across standalone laboratory applications as well as OEM or system-level integration.
Key Technical Advantages
- Gentle, low-shear transfer suitable for sensitive biologics and aqueous solutions
- Very low pulsation characteristics supporting stable process flow conditions
- PTFE diaphragm providing excellent chemical resistance and hygienic performance
- Pump head capable of withstanding up to 10 bar instantaneous pressure shock
- Ball-driven transmission design supporting efficient torque transfer and reliable operation
- Linear speed-flow relationship enabling consistent flow performance
- Self-priming capability supporting flexible system integration
- Hygienic design suitable for CIP and SIP processes
Typical Applications
The TC1200 is suitable for pilot-scale and small production sanitary process applications, including:
- Biopharmaceutical fluid transfer
- Buffer preparation and media delivery systems
- Chromatography purification skids
- Tangential flow filtration (TFF) processes
- Pilot-scale and production process systems
- Sanitary process skids and integrated equipment

Speed-Flow Characteristics
The figure below shows the speed-flow characteristic curves of the TC1200 pump under 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 20–2100 rpm, and the maximum flow rate can exceed 20 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.
