The Stenner Advantage

Pumps Built With A Strong Work Ethic Since 1957

The Stenner Pump Company is committed to manufacturing reliable peristaltic metering pumps for dependable performance. The dependability is built into the pumps.


Stenner pumps are self-priming and deliver consistent output reproducibility


No loss of prime from off-gassing solutions. Self-priming up to 25 feet

  • Solution does not contact moving parts
  • 3-point roller assembly to help prevent backflow, siphoning, overdosing and loss of prime
  • Can run dry without damage and self-prime when the tank is re-filled
  • Degassing valve not required
  • Foot valve or check valve not needed in the pump head

One of the apprehensions of a peristaltic metering pump is replacing the tube which is a part of regular maintenance. Stenner has the answer with two tube replacement methods, both without tools and both patented.

QuickPro® Pump Head and Quick Release Pump Head

Only available from Stenner, the QuickPro® Pump Head. The pump head cover is used to collapse the roller assembly to remove the tube and to expand and lock the roller assembly after the tube has been installed.

The Econ pumps are equipped with the patented quick release pump head. Unlatch the cover, slide it off, and remove the tube. Place the new tube, slide the cover on and latch the cover and you are done.


Stenner pump tubes are manufactured as a single piece construction. During the manufacturing process, the tube fitting is bonded to the tube material making it a stronger connection because the fitting is not attached to the tube material in a separate operation. Tube lubrication in not required

What is a peristaltic pump?

A peristaltic pump is a self-priming pump that achieves pumping action by moving a system of rollers against a flexible tube. The pumped fluids (e.g., chemical feeds) are never exposed to the air or to the mechanical moving parts. The roller design prevents siphoning by providing a constant seal on the pumping tube.*
