An Introduction to Fluid Dispensing Pump

We often see fluid dispensing pump or systems in our daily lives but we do not know that it is called as such because we think that it just one of those pieces of equipment. Little did we know that some liquid dispensing pumps can be found in gasoline stations to fill up our empty tanks while others can be found inside the laboratory.

Fluid dispensing systems are devices used to dispense volumes of liquids ranging from gasoline, diesel, petroleum, gels, paste as well as viscous fluids and gases. Dispensing may be a simple routine yet the process should be taken carefully and seriously. It is very important to know the different classes of chemicals namely: flammable liquids, toxics, corrosive acids-inorganic/organic, corrosive bases-inorganic/organic, flammable solids, oxidizers, water reactive, explosives, and general stock chemicals. Identification of these chemicals should be done prior to dispersal for the technicians to use the proper liquid dispersing system available. 

Dispensing these liquids can be hazardous because of the existence of combustible and flammable chemicals in the liquid media itself. Safety handling of these liquids is of great importance and one must use the appropriate dispensing machines cautiously. There are cases when the liquid causes a spark because it is able to conduct static electricity especially during pumping, pouring or shaking. As a risk preventive measure, manufacturers offer dispensing trials to check for the compatibility of the liquid to be dispensed and the machine. 

There are different fluid dispensing machines and equipment being offered in the market today. Several manufacturers have innovated the simplest yet efficient pumps. Fluid dispensing units are made up of two components. The first one is the embedded computer containing the “powerhouse” of the machine. This also contains the program to run the machine and its displays. The second component is the mechanical component, which physically plumps the liquid being pumped. One may see the nozzles as part of the mechanical and physical component of the system.  

 There are also different types of fluid dispensing equipment being used in the industry namely:

1. Barrel Dispensing System. This is used for dispensing of small amounts of liquid, which can be controlled and measured at 0.0001 cc per shot. The barrel syringe and the dispensing needle are the parts in contact with the liquid making the cleaning part easy after use. Makers of barrel dispensing system also invented nano-sized syringe for precision. 

2. Cartridge Dispensing System. This system is used for handling and dispensing liquids that require more volume than what the barrel dispensing system can hold. Some cartridge dispensing systems can be digitally controlled or through the use of pedals. It can also mix two different types of components evenly. 

3. Computer aided/Robotic Dispensing System. This is designed for multi functional purposes, such as dispensing and mixing of different volumes of liquid and the air. This is suitable for areas where there is limited amount of space available. These robotic systems combine complex programming scripts, let’s be one in thing. 

4. Tube Pump Dispensing System. This equipment is used for dispensing colloids such as gel, glue, and cyano-adhesives. The tubes are easy to clean after dispersal.
