As the most powerful pump from Lotus's Trident range, the 10500 dirty water pump boasts impressive specifications that make it an ideal choice for drainage or supplying waterfalls and filter systems. 

At the base of the unit is a double-filtration intake which not only can take solids up to 8mm in diameter, it features an anti-clog mechanism where the double rotation impeller will reverse the direction of the water flow if a blockage is detected, thereby unblocking itself. This filtration cage is easy to take off when maintenance is required with easy push clips allowing for release. 

This unique water intake system makes this pump ideal for drainage of dirty water, however, this pump can also double down as a filter pump or waterfall pump with its ability to operate 24/7. Simply attach a hose to the top of the fully submerged pump and attach the other end to a waterfall feature that feeds into the body of water holding the pump, or to a filtration system that filters the same body of water. The pump itself comes with a stepped hosetail that can connect to a 25, 32 or 38mm hose.
