Overview

The Normblock Multi is Speck's horizontal, single-stage commercial pool pump with a housing molded from high-performance plastic, so it runs in salt and high-chloride water without internal coatings. It turns at 1,750 rpm on a TEFC motor and uses a carbon/silicon-carbide mechanical seal with a coupling that lets the motor be changed without disturbing the seal. It fits aquatic centers, water parks, fountains, and saline pools that want a quieter, corrosion-proof alternative to bronze or cast-iron end-suction pumps.
