Spec Sheet Manual

Injecting straight into the water line sets the Stennicator apart from traditional medicators and water driven proportioners.

The Stennicator is adaptable to all existing houses with pulsing dry contact water meters, no additional equipment is required. Click here to watch a fun, animated video to see how.
Typical medicators use water to mix stock solutions needed for injection and are adversely affected by poor water quality such as grit, hardness or iron. Poor water quality does not affect the performance of the Stennicator; the pump injects straight into the water line eliminating garden hose bypasses that restrict flow. In addition, the pump is more than just a medicator, it is compatible with a wide range of livestock solutions and can inject strong acids and disinfectants without harm to the pumps’s moving parts. The chemicals are contained in the peristaltic pump tube and suction and discharge lines. All Stenner peristaltic metering pumps are self-priming and do not lose prime from gaseous solutions.
