The Johnson TA3P10-19 macerator pump is specifically designed to dispose of toilet waste using a rotary cutter system and a self-priming flexible impeller pump. The pump is suitable for use with manual toilet pumps and toilets without a macerator fitted.

The Johnson macerator waste pump should be installed directly on the toilet bowl discharge outlet or as close as possible to the holding tank so it can be effectively and entirely emptied overboard.

With a phenol plastic body and a thermoplastic polyester housing, the macerator pump is suitable for use within the marine environment. The waste pump also features a stainless steel shaft as well as a nitrile impeller.
