The MD550 delivers 650 GPH (2,460 LPH) at 40W with up to 2.4 metres (8 feet) of head pressure — a capable unit for medium water features. A fresh impeller assembly brings back quiet, efficient operation when noise or flow loss signals wear.\u003c\/p\u003e\n\u003ch3\u003eWhen to Replace\u003c\/h3\u003e\n\u003cp\u003eMag-drive pumps like the MD550 can run for years without service, but the ceramic shaft and impeller bearing cup gradually wear. The first sign is usually increased noise — a grinding or rattling sound during operation. Flow drop-off follows as the impeller wobbles. Replacing the complete assembly at the first sign of noise prevents further damage to the bearing cup moulded into the pump housing, which is not a field-replaceable part.\u003c\/p\u003e\n\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003eCompatible Pump\u003c\/th\u003e\n\u003ctd\u003eTidalWave MD550 Mag-Drive Water Feature Pump\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eRated Flow (parent pump)\u003c\/th\u003e\n\u003ctd\u003e650 GPH (2,460 LPH)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eMax Head (parent pump)\u003c\/th\u003e\n\u003ctd\u003e2.4 m (8 ft)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003ePower Draw (parent pump)\u003c\/th\u003e\n\u003ctd\u003e40W\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eWarranty\u003c\/th\u003e\n\u003ctd\u003e5-year (parent pump) — OEM part\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003ch3\u003eHow to Replace\u003c\/h3\u003e\n\u003cp\u003eUnplug the MD550 and remove from the water.
