Masterflex® L/S® PTFE-Diaphragm Pump System, Avantor®

Ideal for chemical feed/metering and applications requiring high-purity, high-pressure or both.

• Flow range 80 to 800 ml/min—flow rate depends on drive rpm and tubing size
• PTFE wetted parts help maintain fluid purity
• Pump through filters or into pressurized system
• Check valve on inlet side of pump holds prime for up to two hours when pump is off
• Unique geometry minimizes fluid churning and dead volume for high metering accuracy without reagent contamination
• Accurate and repeatable settings with 3-digit LED display of rpm
• Maximize processes in a minimal footprint by stacking splash-resistant, IP33-rated drives
• Two ways to control speed, direction, and start/stop—use either the membrane keypad or remote-control capabilities

These L/S® precision variable-speed console drives offer precise ±0.25% speed control for accurate flow regulation. The large LED display and LED indicators confirm motor rpm and motor direction at a glance. The complete pump systems include all you need to start pumping.
