What are Immersible Pumps and the Corresponding Applications?

Posted on Mar 25, 2020

For liquid control engineering, immersible pump is a specific type of pumps that is used for a wide variety of commercial and industrial purposes in the market. Pump design is an art that involves hydrodynamics, mechanics of materials, advanced physics, and many other professional science fields. While in regard to liquid water transmission, pumps and valves are important units for workers in the working field. However, pumps are not like valves in many phases. Normally pumps are equipment that moves fluids-state substance such as liquids by its mechanical action.

Traditional view

Traditionally speaking, pumps can be categorized into three major kinds based on the method those pumps exploited to move the targeted substance. As mentioned above, the three categories are based on the methods that pumps used to transmit the targeted substance. For these three types are determined by the way they move the fluids, and there are direct lift, displacement, and gravity methods that people invented in the early stage of industrial development. That is to say, there are three kinds of pumps, one is direct lift pump, and the other is displacement pump, and the last one is the gravity pump. Pumps are typically operated by either typically reciprocating or rotary mechanism, and these all consume energy to perform mechanical work moving the targeted fluid substances.

Meanwhile, on the one side, mechanical pumps can also be submerged in the fluid in which they are pumping, or they can also be placed external to the fluid. The mechanism may be slightly different but the idea of liquid transition shall be the concern for the industrial users and customers.

Moreover, pumps can be categorized by their method of displacement into positive displacement pumps, impulse pumps, velocity pumps, gravity pumps, steam pumps and valve-less pumps. These further categorization help users to decide whether they shall choose what types of pump to deal with their utilization cases. Besides, there are two basic types of pumps, that is, positive displacement and centrifugal pumps. Generally speaking, pumps can operate through many power and energy sources, such as manpower’s’ manual operation, electricity, engines, or even wind power sources or other variations.

Sustainable liquid control technology

That is to day, those energy sources can be a wide variety of equipment which comes in any sizes, from microscopic for use in medical applications to large industrial pumps for waterworks, or ordinary size industrial pump for machine tool coolant transmission. Industrial pumps serve in a wide range of applications such as pumping water from conventional wells, aquarium filtering duty, pond filtering tasks, in the car industry for water-cooling and fuel injection, in the energy industry for pumping oil and natural gas or for operating cooling towers. With the environmental friendly energy sources and a sustainable management, pump and valve planning are to be made in a much more green oriented way that can help users towards a better energy consumption model. In the future, it is estimated that the power sources for industrial usages would be improved no matter it is for pumps or other industrial machinery items since the trend of green energy is now a consensus to the whole world. In sum, only with a sustainable power source supply, can industrial users and commercial activities be able to do in a longer term.
