Stenner Pump Parts and What They Do

  • Pump tubes and tube assemblies. The squeeze tube is the part that wears out. Stenner numbers its tubes #2 to #5 by output range; keep spares.
  • Injection check valves and duckbills. The check valve at the return line keeps pool water out of the tubing. Replace the duckbill when it scales up or stops sealing.
  • Roller assemblies. The rollers squeeze the tube. Worn rollers cut the pump’s output.
  • Feed rate controls, gears and shafts. These set and drive the output on adjustable pumps.
  • Strainers, tubing, nuts and ferrules. Suction line strainers keep debris out; tubing, connecting nuts and ferrules make leak-free connections.

Finding the Right Stenner Part

Read the pump label. Classic Series pumps are numbered by series (45 or 85) and model. Parts marked Series 45/85 fit both.

Match the tube size. Tubing, nuts, ferrules and check valves come in 1/4-inch and 3/8-inch. Use the size your pump is set up for.

Use the diagram. Find the part by its number in the Stenner Classic Series parts diagram at the top of this page.

If the motor or housing has failed, a new pump often makes more sense. Shop Stenner pumps.

Frequently Asked Questions about Stenner pump parts

Which Stenner pump tube do I need?
Stenner numbers its pump tubes #2 to #5 by output range. Match the number on the tube in your pump, and the tubing size (1/4 inch or 3/8 inch) your pump is set up for.
Why is my Stenner pump running but not pumping?
The usual causes are a worn pump tube, a clogged or scaled injection check valve, a blocked suction line strainer, or air in the suction line. Check the tube first, then the check valve and strainer.
Do Series 45 and Series 85 Stenner parts interchange?
Many do. Parts marked Series 45/85, such as check valves, strainers and tube assemblies, fit both. Gears and some feed rate parts are specific to one series, so check the diagram.
