Masterflex® L/S® Variable Speed Analog Console Pump Systems, Avantor®
Don’t lose control of your metering applications—digital display gives you precise control.
- Accurate and repeatable settings with 3-digit LED display of rpm
- Pump fluid in either direction with reversible motor—perfect for purging tubing
- Choose multichannel systems for synchronous flow from all channels
- 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.
