Summary:

This invention focuses on water pumping system used in irrigation system where sprinklers are employed. The pumping device uses BLDC (BrushLess DC) motor to drive the mechanical advantage systems.

There are mainly 5 types of mechanical advantage systems. Positive displacement machines

• This pumping technique has positive displacement systems like piston or plunger or any other similar devices and cylinder with 4 NRV's (Non returning valves) both for inlet and outlet of water at different positions on cylinder.

• Positive displacement system will have the movement with the screw rod attached to driven gear and the driving gear will be the BLDC motor.

• 2 NRV's, which are for outlet, will be located at one side of the cylinder top & bottom. For inlet, one NRV will be to the base of the cylinder and another at the top side opposite to the outlet NRV.
• The whole system will be submerged into the water.
• When the positive displacement system moves up, water will be pumped out of one outlet NRV which is placed at the top of the cylinder and simultaneously water will be sucked inside from the bottom inlet NRV through suction principle.
• When positive displacement system moves down water will be pumped out from bottom outlet NRV and water will be sucked inside through top inlet NRV.
• A special laser based system will always monitor the water level for the submerged pump and accordingly feedback is obtained.
• Large capacities of water can be lifted with minimal effort and mechanical power input is also low.
