How SIMPSON Pressure Pumps Compare to Other Brands

Within SIMPSON's range, the AAA 90036 stands as a top pick for its balance of power and ease, though higher-end models might add ceramic plungers for even greater longevity: choose based on your runtime demands.

Backed by SIMPSON's engineering, these pumps integrate perfectly with Pressure Pumps from leading setups, minimizing leaks and maximizing output.

Installation and Maintenance Tips

Installing a SIMPSON pump like the AAA 90036 is straightforward: align the 3/4" shaft, secure hardware, and attach the siphon tube. Prime the system before startup to avoid dry running.
