Pumps and Pumping Equipments are widely used for moving gases, liquids, or slurries. They do so with the help of mechanical or physical action.  Usually most of the pumps are used for moving volumes from lower places to higher ones. Pumps have become the prime movers in innumerable processes. Pumps encounter endless combinations of pressure, density, viscosity, temperature, volatility, corrosiveness and solvent action, of solids in suspension and gases in solution.

Pumps are a part of various residential, industrial and commercial applications. The most common example of use of pumps in our homes is the water pump that runs every morning to draw water from the ground. Apart from that there are numerous uses of pumps in different appliances like air coolers, refrigerators, washing machines, etc. The size and shape of these pumps may vary from each other but their function remain the same. One can see the application of these pumps in almost all major industries such as aviation, agriculture, chemical, automobile, packaging, printing, mining, paper etc.

Pump Efficiency
The efficiency of pumps is a very important aspect especially in case of industrial pumps. Pump efficiency is the ratio of the power imparted on the fluid by the pump to the power supplied to drive the pump. Efficiency is a function of the discharge and therefore operating head so its value is not fixed for a given pump. You must inquire about these performance data before selecting a pump. Pumps manufacturers provides such data. Pumps should be regularly tested in order to maintain their efficiencies as it tend to decline over time due to wear.

Pump Specifications
Before buying a pump, one should consider the various specifications of pumps and select that one which suits best. Pumps are usually rated by horsepower, flow rate, outlet pressure of head, inlet suction in suction feet of head.
