Description:
The S420 variable speed metering pump injects solution in direct proportion to an incoming 4-20mA analog signal. To achieve the desired flow rate output, the operator scales the pump's response to the signal from 25% to 100% of the maximum flow rate output. The chart on the right illustrates the correlation between the signal received and the pump flow rate output based on the scale setting. When operating in manual mode, the adjustment range is 5% to 100%.
The ability to accept a 4-20mA signal makes the pump well suited for use with water treatment controls including pH and ORP monitors to maintain proper water chemistry and to treat effluent discharge water. Installations can include industrial and municipal waste water treatment facilities and well or surface water treatment for municipalities who supply potable water to residential communities or commercial sites.

Features:
• Totally enclosed housing, NEMA 4X
• Brushless DC motor with ball bearing support
• Three dedicated output relays
• LED pump status indicators
• Remote start or stop
