Sale price$949


The VSH-A600A is a variable speed 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.

Two configurations are available as it relates to the pump's response to the analog signal:

  • Standard Signal Response:  4mA = 0% Output | 20mA = 100% Output
  • Inverted Signal Response:   4mA = 100% Output | 20mA = 0% Output

Designed to operate with our Ultra Class Tubing, this unit is ideal for pumping high volumes and viscous or abrasive fluids. The unit ships installed with a 3/8" bore Ultra Norprene® drive tube. 

Features and Benefits

  • Wide flow range with a 20:1+ turndown ratio
  • Pump head can be set in four different tube positions (up, down, left, right)
  • Accepts continuous lengths of tubing for clean fluid paths
  • Lower ongoing operating costs (ANKO Ultra tubing rolls vs expensive, individual drive tubes)
  • Reversible motor for bi-directional operation
  • Brushless DC motor for long life and maintenance-free use
  • Separate power switch to maintain speed setting when powering unit on/off
  • Flexible internal power supply rating of 100-240VAC 50/60Hz 
  • Viscosity rating of 3000 centipoise
  • Chemical resistant polymer housing
  • Up to 25 psi working pressure
  • UL Listed
  • 3-Year Warranty
  • Made in USA

    INCLUDES:  Drive unit, A603 pump head, 3/8" bore Norprene® drive tube, and 6-ft. (1.8m) NEMA 5-15P power cord. Typically ships within 5 to 7 business days.

    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.
