We have sold Stenner Pumps for years and I have always felt that their pumps were ment to be used  for residential use only.  They just did not make the mark when it came to demanding applications such as Water and Wastewater Treatment Plants.  Bet you didn't see that one coming!


I'm pleased to see the new S Series Peristaltic Stenner Pump.  It is Smart Technology, Simple Programing and Solid Construction,  for Demanding Applications.


The S Series Interfaces with process control systems utilizing a 4-20mA output signal and three relay outputs.  It is rated NEMA 4X, NSF 61 & 372, IP65 (Indoor/Outdoor). You can select from multiple performance indicators and operational modes with intuitive programming and easy navigation.  You can Fine-tune the pump to fit the application; monitor the pump for peace of mind. You can prevent unauthorized access to programmed settings withthe password protection.


In short, the S Series Stenner pump is an "Exciting" pump to use for a good number of applications relating to W/WW Treatment Plants.
