You probably already know that a Stenner Feed Rate Control (Stenner DM5040D) is the key component for the double head adjustable pumps under the Series 100 & 170 releases.

This component is a mechanical control that controls the output on the Classic Series pumps where the higher the setting the more the pump will produce and the lower setting the more restriction is made, which works more efficiently when the pump is mounted vertically for longevity of the feed rate control.

Despite such signature features offered, the Stenner Feed Rate Controls are still subject to a definite lifespan. We can address this concern by creating this category as the reference site for all the genuine replacements you need in case your controls no longer function as intended or the shaft that comes with them is broken.

The first component we have in this list is the : Fc5KOOD Stenner Brass Index Spider D". This is a vital component that helps in letting your control have at least 10 different settings and be able to be mounted vertically.
