The History of Mission Pump and Its Types

The history of mission pump can be traced back to a liquid lifting machine that appeared as early as 1700s in a scientific paper written by a British engineer. However, true Mission pump was not developed until the late 18the century. Modern Mission pump consists of pressure side, downstream pipe flange, rotating direction indicator, pump casing, volume chamber, impeller, suction side, and upstream pipe flange. It is marked by low heat transfer from the electric motor because the pump chamber is in general isolated from the motor by an air gap, which creates a thermal barrier. What is more, the modern model is capable of separating the liquids completely so that they will not seep into the motor from the pump. In general, Mission pump is used to transport fluids such as water and petroleum through the conversion of energy forms. To be more specific, most Mission pumps feature rotational kinetic energy turning to the hydro dynamic energy of the fluid flow and the rotational energy often comes from the electric motor or engines. As a matter of fact, Mission pump is commonly used in such fields as water, sewage, petroleum and chemical pumping.

There are a variety of Mission pumps. First of all we have the vertical Mission pump in early 20th century. It features a unique shaft and bearing support that helps to reduce friction. However, if the load of the pump is too great, it will get damaged as a result. This type of Mission pump does not have any stuffing box to seal the shaft. On the other hand, it utilizes a throttle bushing and is widely used as one component of a washer.

In addition, we have froth Mission pump, which is specially designed for the mineral industry and the oil drilling industry. In the beginning the froth is generated to separate the rich minerals from the sand and clays. Over time it can also be used to separate solids from the oil drilling products. However, since froth Mission pump contains air, at times it might block conventional pumps. Fortunately, the pumping industry has figured out different ways to cope with this annoying problem. For instance, some engineers came up with the approach of using vertical Mission pump with a tank while some others developed the approach of building special pumps with a specially made impeller capable of breaking the air bubbles. In this way, the air will be discharged back to the tank and the possibility of leaks and friction loss will be largely reduced. Thus, the froth Mission pump is capable of providing complete separation of fluids from the pump drive. What is more, the noise of the froth Mission pump can be greatly cut thanks to these two approaches.
