Description
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. 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
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.

Notes to Flow Chart: 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. |
