A fluid pump device comprised of high-strength permanent magnets forming chambers through which the liquid passes and inter-chamber opposing electrode plates with an applied DC potential provide the magnetic flux density and electric current for generating the Lorentz forces acting on the liquid. The fluid pump device may be combined with a desalination filtration device for provision of fresh water near the end of the distribution line without the need for a largescale treatment plant. Desalination/filtration occurs through use of nano-porous graphene and/or carbon nanotube media. ## Claims ### Claim 1 A system for transporting and desalinating a liquid, the system comprising: a saline liquid intake device in fluid communication with at least one fluid pump device, the fluid pump device comprising an inflow manifold and/or an outflow manifold, each manifold comprising a plurality of fins spaced to smooth the turbulence of a saline liquid flowing therethrough, and at least one chamber through which the saline liquid may flow, the fluid pump device capable of generating a non-impinging motive force to effect the movement and transport of the saline liquid through a piping system in fluid communication therewith;
