Stenner M128 Peristaltic Pump - 1:128 Medicator - M128 Series
The M128 peristaltic pump delivers reliable injection at a 1:128 proportion for livestock water treatment.
The M128 series was specifically designed to inject solutions at a 1:128 ratio to treat livestock water with sanitizers, disinfectants, nutrients and medications. Also referred to as a medicator, the pump will automatically meter solution proportional to the water flow at a rate of one ounce of solution to 128 ounces of process water. For convenient and quick installations or turnkey operations, the M128 System is equipped with the pump and corresponding dry contact 3/4" or 1" Water Meter mounted on a heavy duty panel.
What sets the M128 apart from other medicators is the simple service which is periodic replacement of the pump tube and one piece check valve at the injection point. Read about Stenner’s QuickPro® pump head and effortless tube replacement.
The M128 series is available as two models, the M05 or M07. The primary differences are the output capability and pressure rating. Most livestock operations have a pressure reducer in place to drop pressures to a manageable level at the drinker lines. Injecting after the pressure reducer is an option, if higher outputs are needed.
- M07: 3.5 oz/min up to 100 psi (105 ml/min up to 6.9 bar)
- M05: 8.4 oz/min up to 25 psi (249.7 ml/min up to 1.7 bar)
