The Gulper Grouper MK3 boasts 90° port orientation for direct replacement of existing macerator pumps in compact areas. Unlike macerator pumps, non-choke Gulper valve technology means no filters, and no clogged impellers with associated motor burn out. Pump is equally dependable for bait box evacuation or for pumping toilet waste. Equipped with 360° head rotation, makes lining up hose connections a cinch. Easy to clean and maintain.
