Referring to the first embodiment shown in Figures 1 to 8 in which the primed pressure can be gas or liquid. The first stage can include a first flexible bladder that can be partly or fully inflated and deflated. 5 Fluid communication between the first stage and the second stage bladder is achieved though connection means. In the preferred embodiments, the invention provides a pump for use in a desalination system. In accordance with the invention there is provided a pump apparatus for use in a multi-stage pump system for use in a desalination system that includes multiple stages wherein the first stage includes a combination of a plurality of bellows, cylinders and pistons connected to a buoyancy system that moves up and down according to wave motion of the water that draws air from the atmosphere to provide a compressed air source for priming subsequent stages. • Air supply is primed by a plurality of bellows, cylinders and pistons that draw air from the atmosphere.
This fluid transmission pipeline includes a plurality of non return valves to prevent back flow of the liquid that is being pumped. The valves control whether the gas flows to the piston and cylinder or to the flexible bladder is stages two and three. With reference to Figure 2, as the air pressure builds up, the FB continues to inflate until the buoyant force exceeds the force generated by the air pressure in the Larger Lower Cylinder 21 (LLC) previously holding the larger lower piston 22, (LLP) down at the bottom of its stroke. The flexible bladders are formed from a buoyant material. The valve that regulates flow through the return air line from the FB is closed at this stage, as is the main exhaust valve from the FB. The bladder is in fluid communication with the cylinder in the form of flexible tubes.

Depending on the volume of water needed, multiple pumps are sometimes needed, which increase the power overhead costs with each pump that is used. The pump apparatus for use in a multi-stage pump system can include multiple stages wherein one stage that receives gas from an outside source includes a cylinder including a reciprocating piston attached to and in fluid communication with a flexible bladder that is inflated by the low pressure gas and deflates when the gas is forced toward the cylinder such that an complete stroke of the piston includes air flowing from the outside source into the flexible bladder, inflating it and increasing the buoyancy of the bladder, drawing it and the piston up, once the bladder has risen to the apex, the bladder will deflate, forcing air into the cylinder augmented by air from previous stages and push the piston down this complete stroke creates a pumping force to draw water into the cylinder through an inlet port and then expel it through an outlet port outputting to use or further stages.
At least one piston is attached to a float that moves up and down according to wave motion of the ocean. 5 The pumping system includes a third stage that that is in fluid communication with both the first stage and second stage, wherein the third stage drives a second reciprocating member through a stroke. The present invention in one aspect provides a apparatus for use in a multi-stage pump system for use in desalination systems that includes: a first stage for priming the system; a second stage that is in fluid communication with the first stage and is primed by the low pressure air from the first stage wherein the second stage drives a first reciprocating member through a stroke to create an increased pressure; and wherein the second stage having an inlet point for drawing fluid from a fluid source when the first reciprocating member undergoes a stroke, the fluid then passes through a passage to and expelled to an outlet point at higher pressure when the first reciprocating member proceeds through a complete stroke.
Finally in Figure 8, The BPA continues well on its downward stroke.
The second and third stages (and any subsequent stages) also include an emergency release valve, 34. This valve can be activated when the flexible bladder, 23, requires swift deflation in emergency or in preparation for down time. The need for clean drinkable water has increased over the last century. Finally in Figure 8, The BPA continues well on its downward stroke. Figure 18 shows the stroke of the pump apparatus for use in a multi-stage pump system of Figure 9 at dead set bottom with the downward stroke complete with the bladder completely deflated ready to repeat cycle. The stroke is shown at top dead centre in Figure 6 as the cylinder piston is preparing to resume in a downwards direction.

This seal can be achieved with a combination of piston cups and “O” rings, 27, which prevents liquid from filling the cylinder, 21 , between the extreme ends of the piston, and also prevent air from escaping. • Flexible tubes provide fluid communication between stage one with stages two and three such that the air taken from the atmosphere can be sent to the two other stages. In the last fifty years the desalination of sea or brackish water has improved such that it is becoming an affordable option for nations that are in need of fresh water.
