Questions about this item

How often should the impeller on the MQB-4500 be cleaned or replaced?

The impeller is the only moving part inside the pump. Inspect it every three months and clean off any algae or debris; replace the impeller assembly if the blades show wear or the magnet has cracked.

What limits continuous running of the 100 W motor on the MQB-4500?

The motor is rated for 100 W at 220-240 V 50 Hz. Thermal protection will trip first if the pump runs dry or the outlet is restricted, so keep it fully submerged and the flow path clear.
