Stenner has almost a hundred different pumps, but don’t let that scare you. We can help you narrow your search down in just a few quick, easy steps.
Stenner Classic Series Pumps – These are the pumps Stenner has been making for decades. They are available as follows:
Stenner ECon Series Pumps – These new pumps are economy priced for residential and light commercial applications especially if the water pressure is under 80 psi.
Stenner SVP Series Pumps – This is a variable speed pump that activates in a 4-20mA mode from an input signal. If that doesn’t sound familiar to you, you probably don’t need this pump.
Stenner M128 Proportional Pumps – Specifically designed for the agricultural and livestock industry for use with sanitizers, disinfectants, nutrients and medications. Oft-times it is called a “medicator.”
Stennicator Proportional Pumps – Engineered specifically for medicating in the poultry industry, it is also designed to keep the birds hydrated and healthy.
Note: If you are a homeowner or involved with a Stenner Pump in a residence, the odds are, you will need a Stenner Classic High-pressure model.
The quick answer is that if you are using it for a water treatment system that has a pressure control switch and the pressure is over 25 PSI, then you need a high pressure pump – plain and simple! However, if you are pumping a chemical into a system where there is less than 25 PSI back pressure, such as a pool recirculation system or cooling tower or atmospheric tank, then a low pressure system will suffice.
If you aren’t sure, then opt for the adjustable model. You will use the fixed output model if you are circulating or running water at the same rate all the time. If not, you will have need of adjustments.
If you are injecting just one chemical, then you will use a 45 or 85 Classic Series Stenner Pump which has a single head, but if you are injecting two chemicals, then it might be wise to use a 100 or 170 Series Stenner Pump which has a dual head.
