Stenner Chemical Pumps

Choosing the right Stenner pump for a swimming pool comes down to whether or not you are using a chemical controller.

If your pool uses a chemical controller such as CAT Controllers, Rola-Chem, Chemtrol, or BECSys, a Classic Series fixed-flow Stenner pump is the best choice. The controller decides when the pump runs, and the pump delivers a steady, consistent amount of chemical.

If you are not using a chemical controller, a Classic Series adjustable-flow Stenner pump gives you the ability to manually fine-tune chemical output. This makes it a good option for pools that rely on manual testing and adjustments.

In simple terms, choose a Classic Series fixed-flow pump when using automation and a Classic Series adjustable-flow pump when you are not. This helps ensure accurate chemical dosing and stable pool water.

Choosing between Santoprene and Versilon tubing depends on the type of chemical you plan to inject with your Stenner Pump Company pump. Different chemicals react differently with tubing materials, so selecting the correct tube is important for performance, longevity, and safety.

To make the right choice, Stenner recommends reviewing their official chemical resistance guide, which outlines tubing compatibility for a wide range of chemicals commonly used in pool, water treatment, and industrial applications.

In short, always match the tubing material to the chemical being injected to ensure proper operation and long tube life.

Each Stenner Pump Company pump includes an accessory bag with the essential components needed for installation. While contents may vary slightly by model, Classic Series fixed-flow and adjustable-flow Stenner pumps typically include the following items:

• Three connecting nuts in 1/4 inch or 3/8 inch sizes
• Three ferrules in 1/4 inch or 6 mm (European) sizes
• One duckbill check valve rated up to 100 psi (6.9 bar) or one injection fitting rated up to 25 psi (1.7 bar)
• One weighted suction line strainer in 1/4 inch, 3/8 inch, or 6 mm (European)
• One 20-foot roll of suction and discharge tubing in 1/4 inch or 3/8 inch, available in white or UV-resistant black, or 6 mm white (European)
• One additional replacement pump tube
• Two additional latches
• One mounting bracket
• One product manual

These included accessories help ensure a smooth and straightforward installation, whether the pump is being used for swimming pool chemical injection or other water treatment applications.

Tubing replacement depends on how the pump is being used, but a good rule of thumb is to check it regularly and plan on replacing it about once a year in most pool applications.

If you are running the pump continuously or using stronger chemicals like chlorine or acid, you may need to replace the tubing more often. Signs it's time for a replacement include cracking, stiffness, discoloration, or a drop in chemical output.

Staying ahead of tubing wear is important because fresh tubing helps keep your Stenner Pump Company pump running accurately and prevents unexpected downtime.

Choosing the right pump size comes down to your pool volume, your chemical demand, and whether you are dosing chlorine, acid, or both.

A smaller pool with light chemical demand will typically need a lower output pump, while larger commercial pools or pools with higher bather loads will require a higher output model. It also helps to consider how quickly your pool tends to lose chlorine or drift in pH, since that impacts how much chemical needs to be added daily.

If you are unsure, it's usually better to size slightly higher and fine-tune output settings or runtime, especially if you are using a controller or timer system. This helps ensure you can maintain stable water balance without running the pump constantly at maximum capacity.

While it never hurts to have a professional handle installation or service, Stenner Pump Company pumps are designed with the end user in mind. They are built to be straightforward to install, operate, and maintain without requiring specialized tools or advanced technical training.

Most basic maintenance and service tasks can be done by the user with the help of Stenner's Basic Service Manual, which walks through routine upkeep and common procedures. This makes it easier to stay on top of maintenance, reduce service costs, and keep your pump running reliably.

In short, professional service is optional, but not required for most installations or routine maintenance, especially if you follow the manufacturer's guidance.
