Classic Series Single Head Adjustable Pumps

The Single Head Adjustable Output pump is one of the varieties in the Classic Series of Stenner brand.

The Model 45 operates at 26 RPM, while the Model 85 runs at 44 RPM. The actual output depends on several factors, including the motor gear speed, the selected feed rate setting, and the size of the pump tube. An external dial ring on the feed rate control allows for easy manual adjustment. This dial is marked from L to 10, enabling users to set the pump output anywhere from 5% to 100%, providing a 20:1 turndown ratio with fine 2.5% adjustment increments for precise control.
