Gear pump is the ideal machine for the transferring of liquids in industrial operations. They operate with a pair of gears - a driver and an idler Gear - where the fluid is drawn into the suction created by the vacuum The idler pressed tightly against the driver, is driven by the gear reducedotor to prevent slippage and loss of pressure. As the gears spin, they ensnare fluid between the gear teeth and pump casing and push it from the suction end to the discharge end. This never-ending process is what enables gear pumps to effectively pump fluid from one point to another.
Since they are able to operate with a variety of fluid viscosities, gear pumps offer a number of applications. They are also popular for their high efficiency and modest cost in comparison to other pump designs. Yet, gear pumps can be prone to abrasion, particularly when utilized with abrasive liquids. They are also very slow to self-prime enough to be used without pre-priming.
There are a number of things you will want to consider when selecting a gear pump for your application. among other things, will be flow rate and pressure characteristics needed by your pump application, viscosity and temperature of the fluid being pumped, the materials of construction and any other special considerations or limitations of your application. Considering these factors carefully will help you to choose the right gear pump and guarantee best performance.
Like any piece of equipment, taking proper care of your gear pump can be the difference between getting the most out of it and dealing with expensive maintenance costs. Here are some important pieces of maintenance, the first being to make sure you are checking, and replacing where needed, gears, bearings and seals that have worn over time that could lead to leaks and lost efficiency. The pump temperature and pressure during use should be also checked and fixed promptly. Also, the pump must be kept clean and free of debris to avoid clogs that can damage the internal mechanisms.
In the end, the right gear pump for the job will be a function of the needs and constraints of the particular application. If you require a pump that is capable of pumping a very wide range of fluids of varying viscosities and temperatures, then a gear pump might be the right pump for your application. But if you need the pump to have self-priming and you're dealing with abrasive fluids, you might want to look at other pumps.
