VSL A300A | Variable-Speed | Scalable 4-20mA | Brushless DC | Models to 1100 mL/min (400 GPD)

The VSL-A300A is a variable-speed, peristaltic metering pump that can be controlled manually, or by an incoming 4-20mA analog input signal. The analog function permits direct proportioning of dosed fluids according to the level of input signal (4mA = 0% output; 20mA = 100% output). The pump's maximum output to the signal is scalable from 20% to 100%, as determined by the potentiometer setting.   The pump ships configured to utilize our long-lasting, Premium Class Tubing formulas and includes drive tubes (bore sizes: 1/4", 3/16" & 1/8") of Premium Norprene®, providing the flexibility of three unique flow rates.  Features and Benefits Wide flow range with a 20:1+ turndown rate Smooth and accurate control with +/-2.0% speed regulation Reversible motor for bi-directional operation Separate power switch to maintain speed setting when powering unit on/off Brushless DC motor for a long, maintenance-free life Medical-Grade, 100-240VAC 50/60Hz internal power supply  Up to 25 psi working
