Best suited for precise chemical infusion/metering and high-purity, high-pressure transmission applications ■ A Masterflex L/S driver is configured as a chemically inert diaphragm pump - PTFE can resist the most corrosive chemical corrosion ■ The unique geometric design of U minimizes fluid agitation and dead volume, thereby improving metering accuracy - reproducibility maintained at ± 2% ■ Irritable pump - loaded or unloaded ■ Intermittent pressure: can maintain the pressure of continuous fluid at 6.9 bar
Masterflex®L/S®PTFE diaphragm pump head

The most suitable for precise chemical infusion/metering and high-purity, high-pressure transmission applications
Prepare a Masterflex L/S driver as a chemically inert diaphragm pump - PTFE can resist the most corrosive chemicals
The unique geometric design of U minimizes fluid agitation and dead volume, thereby improving measurement accuracy with reproducibility maintained at ± 2%
■ Irritable pump - loaded or unloaded
Intermittent pressure: can maintain the pressure of continuous fluid at 6.9 bar
Attention: For L/S drivers that can accommodate 2 or more pump heads, it is recommended to operate within a speed range of 40~400 rpm.
