Product Overview

Self-priming macerator pump for waste holding tanks, fish boxes and livewells.

The ideal solution for emptying marine holding tanks when not in a discharge restricted area; this macerator, due to its self-priming design, is also a great choice for emptying livewells and fish boxes which are somtimes located below the waterline. The pump includes run-dry protection with a self-priming flexible impeller and stainless steel wear plate. Self-priming to 4' when wet and grinds waste to 1/8" or smaller. The fail-safe design detects the absence of fluid then shuts off pump before impeller is damaged. Sensor provides adequate run-dry period to allow initial priming of the pump. The inlet port has a 1 1/2" hose barb combined with 1 1/2" male thread to screw directly onto a tank flange. Use 1"–1 1/2" hose adapter (Model 3274123) for 1 1/2" sanitation hose. Flow rate to 10 GPM.
