primary cannot. For dependable, high-performance, long lasting service nothing beats a modern Primo

Belt Drive systems

the most popular in the world! That same quality & performance is now available in the Brute III EXTREME

mare is over, no more leaky primary, no more draining the primary for inspection or maintenance. Carefully

read & follow these instructions for a quick, convenient installation. If you have questions call (562) 907-2600.
