Stenner's S128 Medicator Pump

The S128 adjusts to the system flow rate for even distribution of product into the water line.

The S128 is designed to automatically inject solution into the water line proportional to the system water flow at a ratio of 1 ounce of solution to 128 ounces of process water. Activated by a dry contacting pulse water meter, the pump automatically adjusts to the water flow.



As the pump registers dry contacts, it delivers the precise ratio. The pump has three speeds to automatically adjust the injection rate when the water system flow rate increases or decreases. This flow response design allows the pump to evenly and proportionally inject solutions especially at low system flow rates. The S128 and the low flow VPD water meter are ideal for early stage poultry flocks and swine nurseries when water flow is minimal. The pump's relays allow use of an existing water meter and controller.



Injecting undiluted chemicals directly into the water line eliminates water restriction and the daily mixing of stock solutions. In addition, the pump is unaffected by poor water quality.
