What is mission pump ? In general, Mission pump is widely used in a variety of industrial, domestic and vehicular pumping applications such as oil drilling pumps, multi-stage deep well pumps, mixing pumps, hydrocarbon pumps, transfer pumps, etc. For instance, Mission pump can be applied in processing low viscosity fluids without complications that contain some kinds of hard solids. Mission pump can be single staged or be stacked together in a flow arrangement in order to deliver high output pressures during the processing.

As a matter of fact, Mission pump is relatively simple in concept and construction. What is more, marked by the capability of delivering high flow performance at moderate pressures, Mission pump main parts are available in all materials--including all metals, plastics, and ceramics. The transfer of energy from the mechanical rotation of the Mission pump impeller is often referred to a fictitious force by engineers and scientists in a rotating reference frame. And the outlet pressure is a typical reflection of this fictitious force that tracks the path of the fluids to move inside the Mission pump.

Most Mission pumps are powered by electric motors. A majority of such kinds of motors operate at the speed of 1800 to 4000 rpm. A Mission pump converts mechanical energy from a motor to energy of a moving fluid. As a matter of fact, while a portion of the Mission pump energy goes into kinetic energy of the fluid motion, the rest turns into potential energy that is represented by fluid pressure or by lifting the fluid against gravity to a higher altitude. Among all the Mission pump main parts, the bladed impeller might be the most important component. In most cases, the bladed impeller is firmly attached to the Mission pump shaft, which is often an extension of the motor shaft.

In addition, the impeller is generally located inside a round recess in the Mission pump and a smooth outlet channel would leave the round recess tangentially. However, it should be pointed out that Mission pump is in general not self-priming. In other words, most Mission pumps must be full of liquid before they can start pumping. This is particularly true when the height of the Mission pump is above the liquid level being drawn to the pump. On the other hand, the tank receiving fluids such as water and petroleum from the Mission pump can be higher than the pump. For instance, every twenty feet of petroleum height is equivalent to about 20 psi. Thus, if a Mission pump has an output pressure of 60 psi, the receiving tank can be located about 50 feet above the pump at most.
