Please send ppt and report of the topic "pistonless pump"

A pump without a piston is a type of pump designed to move fluids without moving parts other than three-chamber valves.

The pump contains a chamber having a valve inlet from the fluid to be pumped, a valve outlet - both at the bottom of the pump, and a pressure port at the top of the pump. A pressurant is used, such as pressurised steam or helium, to conduct the liquid through the pump. NASA has developed a low cost rocket fuel pump that has comparable performance to the turbo-pump at the lowest 80-90% cost. Perhaps the most difficult barrier to entry into the liquid rocket business is the turbo pump. A turbo pump design requires a great deal of engineering effort and is expensive to mfg. And test. Starting a turbo-charged rocket engine is a complex process, requiring a lot of valves and subsystems. In fact, Beal aerospace tried to avoid the issue altogether by building a huge pressure feed booster. His booster never flew, but the engineering behind it was good and, if they had a low-cost bomb at their disposal, they could be competing against Boeing. This pump saves up to 90% of the mass of tanks compared to a pressure feed system. This bomb has proven to be a boon to rockets. By this pump the rocket does not have to load the heavy load and can travel with very high speed.
Almost all hardware in this pump is made up of pressure vessels, so the weight is low. There are less than 10 moving parts and there are no lubrication problems that can cause problems with other pumps. Design and construction. This pump is st, forward and no precision parts are required. This device has advantage over std. Turbo-propellers in that weight. It is about the same, unit, engg. and test costs are less and the chance for catastrophic failure is less.This pump has the advantage over pressure fed designs in that wt. The whole rocket is much smaller and the rocket is much safer because the rocket fuel tanks do not need to be under high pressure. The pump could be started after being stored for an extended period with high reliability. Can be used to Replace turbo-pumps by rocket propeller. Or it can be used to replace high pressure tanks for deep space propulsion. It can also be used for satellite orbit changes and station maintenance.
