Macerator pump apparatus with an integral waste valve assembly and a quick disconnect discharge assembly

摘要

A macerator pump apparatus (MPA) includes a waste valve assembly (WVA), a macerator assembly, a pumping assembly, and a quick disconnect discharge assembly (QDDA). An inlet port of the WVA receives waste matter from a waste holding tank (WHT). A valve member positioned within the WVA directs flow of the waste matter to the macerator assembly and isolates the waste matter within the WHT by closing the valve member before the MPA is disassembled for maintenance. The macerator assembly macerates the waste matter and transfers the macerated waste matter to the pumping assembly and to a discharge port of the QDDA. A quick disconnect member detachably connects an outlet plumbing pipe to the discharge port via a quick disconnect valve (QDV) for discharging the macerated waste matter. The QDV isolates the macerated waste matter within the outlet plumbing pipe by closing the QDV before the MPA is disassembled for maintenance.
