Whale Gulper MK2 12V Toilet Waste Diaphragm Pump

The Whale Gulper MK2 is a 12V waste pump intended for unmacerated toilet discharge. Its diaphragm-based design can move a mixture of air and waste without a separate filter. This is the bulk-packaged configuration rather than a retail-boxed accessory kit.

Whale's non-choke valve system is intended to reduce clogging in waste-water use. The pump can run dry without damage, which is useful during the final part of an emptying cycle. It still needs properly sized plumbing and a suitable discharge arrangement for the marine sanitation system. Because unmacerated waste is more demanding than ordinary shower water, the dedicated pump type matters.

The supplier specifies CE certification and cites ISO 8846 and IP45 among its compliance information. A three-year warranty is listed for the model. Before replacing an existing toilet pump, confirm the 12V power supply and the waste-handling role of the original equipment. Browse more macerator and waste pumps at CritPro.
