Chemyx High-Pressure Syringes – Maximum Pressures

Chemyx Stainless Steel Syringes can be used with the Fusion 4000-X and Fusion 6000-X models. The table below shows the maximum pressure for each Stainless-Steel Syringe compatible with the following Chemyx syringe pumps. These values are theoretical calculations based on the formula found in the following article – “How To Calculate Syringe Pump Pressure“.

Syringe SizeI.D. Inner Diameter (mm)Fusion 4000-X Approximate Max Pressure (psi)*Fusion 6000 Approximate Max Pressure (psi)*
200mL44 –250
300mL54 –150

*Note – Proper syringe O-rings need to be utilized if there is a leakage to achieve maximum pressures. Lubricating guide rods, lead screw, and proper maintenance is required to reach maximum pressures. Buna-N has a durometer rating of medium-hard. For higher pressure syringe pump applications, a hard/very hard O-Ring (PTFE) needs to be utilized.

This is measured data

*Warning do not use any of the Chemyx Syringe Pumps for high-pressure gas applications.
