Summary:
This invention describes the mechanical advantage systems used in underground fluid pumping system and it is driven by compressed air engine or effluent gases emitted by any device like diesel generator set, boiler etc. There are mainly 3 types of mechanical advantage systems.
Positive displacement system
• This pumping method will have 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 systems will have the movement with the screw rod attached to driven gear and the driving gear will be the compressed air engine.
• Two 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.
• Inlet NRV's will be connected to a pipe and this pipe will be immersed into the water for suction of water.
• When the positive displacement systems 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 the positive displacement systems moves down water will be pumped out from bottom outlet NRV and water will be sucked inside through top inlet NRV.
• Large capacities of water can be lifted with minimal effort and mechanical power input is also low.
Rack and Pinion system
• This pumping method has a positive displacement systems like piston and cylinder with 4 NRV's (Non returning valves) both for inlet and outlet of water at different positions on cylinder.
• Piston will have the movement with the rack & pinion attached to the driving gear of the compressed air engine.
• 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.
• Inlet NRV's will be connected to a pipe and this pipe will be immersed into the water for

suction of water.
• When the piston 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 piston moves down water will be pumped out from bottom outlet NRV and water will be sucked inside through top inlet NRV.
• Large capacities of water can be lifted with minimal effort and mechanical power input is also low.
Pulley system
• This pumping method has a positive displacement systems like piston and cylinder with 4 NRV's (Non returning valves) both for inlet and outlet of water at different positions on cylinder.
• Piston will have the movement with the rope pulley attached to the unidirectional pulley system. This unidirectional pulley system is driven by compressed air engine.
• Counter weight will be added to the piston for the downward movement.
• 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.
• Inlet NRV's will be connected to a pipe and this pipe will be immersed into the water for suction of water.
• When the piston 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.

4. Description
The field of invention relates to an underground fluid pumping device without consuming either electricity or any fuel. This invention uses the principles of nano technology and mechanics to pump fluid from a closed or bore well pump.
In pumping method, cylinders are cascaded with each other stage wise and vacuum is created among them. The length of cylinder never exceeds 32 ft, and hence multiples of 32 ft cylinders are connected. Vacuum is created using vacuum pump. Once vacuum is created, all the cascaded pipes, water continuously will be pumped until bottom flow is stopped.
More than 85% of the total cost incurred over the lifecycle of a pump is towards consumption of electricity. Hence this invention cuts down the electricity cost which leads to the massive economic benefits. Cylinder inner surface is sputtered with graphite nana material to minimise frictional resistance. This further increases the efficiency of the system.
Background of invention
Several pumping systems involving different pumping and extraction devices have been developed for transfer of fluids from a closed/ bore well. These pumping systems run on AC motor and requires electricity for operation and the electricity consumption increases as the depth of suction increases. In case of Centrifugal pumps, the efficiency tends to decline as flow rates rise after peak efficiency is reached. The pump efficiencies also tend to decline over time to wear. In case of plunger pumps, lot of energy is wasted when the fluid is accelerated in the piping system, hence decreases efficiency of any plunger pump system.
The present invention makes the design simple with nano materials and makes corrosion free. The efficiency remains high throughout the pump lifecycle as the nano material is very less prone to wear out. The pumping system requires a very little/no power because of mechanical advantage principle involved in it. Hence it eliminates the cost incurred in expensive maintenance, cable cost, panel boards and frequent motor burn outs making the system complete electricity independent.

6. Brief description of drawing:
• Inlet of the pump is connected to a pipe.
• The other end of connected pipe is dipped in closed well or bore well.
• This pipe is split into two parts.
• Each splited pipe is connected to an inlet NRV, which is connected to cylinder.
• There is a piston in cylinder which is connected to screw rod.
• This screw rod is displaced using internal threads of a gear which is driven by other gear connected to air compressed engine.
• When piston reciprocates, fluid inside cylinder come out through other set of NRVs which are connected to a pipe which serves as outlet.
