Pumps
Restore powerful, reliable flushing with a genuine Dometic MasterFlush 7640 macerator pump and motor assembly. As a true pedal-operated macerating toilet, the 7640 relies on its integrated dual-stage impeller/macerator pump to grind waste and pump it up to 40 feet to your holding tank — a worn or failing pump is a common cause of weak flushing, grinding noises, or a toilet that fills but won't fully clear. Shop the genuine replacement macerator pump and motor assembly built specifically for the discontinued Dometic MasterFlush 7640 toilet, so you can keep your motorhome or fifth wheel's original macerating system running reliably.
