In a submersible pump having a pump casing presenting a top with an opening therein and a electric motor in the casing for driving the pump, the improvement comprising:

• a handle adapted to be grasped by the hand, said handle having a barrel projecting therefrom;
• means for attaching said handle to the casing with said barrel extending through the opening and with the handle accessible for grasping to lift and carry the pump;
• electrical conductor means extending through said barrel to supply electrical power to the motor;
• a generally annular flange on said barrel projecting outwardly therefrom;
• a seal ring extending around the barrel and interposed between said flange and the top of the pump casing to effect a water tight seal when the handle is attached to the pump casing;
