Description
The VSP-A300A is a variable-speed, peristaltic metering pump that can be controlled locally, or remotely through an incoming 4-20mA analog input signal. Utilization of the analog feature allows for direct proportioning of dosed fluids according to the level of input signal. The pump's maximum output to the signal can also be scaled from 20% to 100% by the potentiometer's percentage setting.
Available in two analog signal response configurations:
-
Standard: 4mA = 0% Output | 20mA = 100% Output
- Inverted: 4mA = 100% Output | 20mA = 0% Output
Each unit 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 distinct ranges of output.

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. |
