Description
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. The pump's maximum output to the signal is scalable from 20% to 100%, as determined by the potentiometer setting.
Available in one analog signal response configuration:
- Standard: 4mA = 0% Output | 20mA = 100% Output
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.

Notes to Flow Chart: *Unavailable for Premium Class Tubing Flow rates are for guidance purposes only and are based upon pumping ambient temperature (22°C/72°F) water at zero pressure and zero lift. Rates may increase/decrease based upon numerous factors including: motor variances, tubing characteristics, fluid viscosity, lift height, pressure and number of rollers. Anko reserves the right to make changes at any time without prior notice. The information provided is not intended for a specific application purpose. |
