Features
Deltec E-Flow Pumps are almost silent in operation due to the all new DC brushless motor.
All Deltec E-Flow Pumps are protected by an over load protection circuit and if the impeller becomes blocked the pump is switched off automatically.
All models include a control panel that allows the pump to be adjusted for power output . By using the up and down buttons on the control panel power output in watts can be adjusted electronically in 13 stages (E-Flow 10) down to 20 watts.
If power is lost the pump will restart at its old power setting.
