E-Flow 12 24v 

Deltec's new flag ship series of true sine wave pumps driven by brushless motors. The included controller can set power consumption and performance via a wattage display.
The pump can either be installed inside or outside a sump. The new E-flow Pumps provide a high flow rate and pressure at low power consumption and are almost silent in operation.

E-Flow 12 - Silent running external and internal pump with a 11,400 lt/hr duty.


  • Deltec 24v 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 12) down to 20 watts.
  • If power is lost the pump will restart at its old power setting.
