Stenner S Fixed or S Variable Series Pumps

The S Series is an intelligent peristaltic metering pump designed to work seamlessly with process control systems using a 4–20 mA signal and three programmable output relays.

Engineered for tough industrial environments, the pump features a rugged, fully enclosed NEMA 4X rated housing that protects internal components from moisture, dust, and corrosive conditions. It is powered by a brushless DC motor with ball-bearing support, ensuring reliable performance and long operational life. The switch-mode power supply also improves overall energy efficiency.

To maintain system security, password protection restricts unauthorized changes to programmed settings. The system also supports automatic transfer from the primary pump to a backup S Series pump, helping maintain uninterrupted operation.
