VSL L400A | Variable-Speed | Scalable 4-20mA | Brushless DC | Models to 3000 mL/min (1100 GPD)

The VSL-L400A is a precision, 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.   VSL-L400 Series pumps can be ordered to utilize Performance Class Tubing (VSL-L401 Models) or Premium Class Tubing (VSL-L402 Models), giving them the ability to perform in a wide range of applications. The pump ships with samples of 1/4", 3/16” & 1/8” bore Norprene® tubing according to the model type selected. Features and Benefits Rapid loading pump head with automatic tube retention Wide flow range with a 20:1+ turndown rate Smooth and accurate control with +/-2.0% speed regulation Convertible to alternate tubing class usage with change of Roller Assembly (sold separately) Reversible motor
