a vacuum pump converts the mechanical input energy of a rotating shaft into pneumatic energy by evacuating the air contained within a system. The internal pressure level thus becomes lower than that of the outside atmosphere. The amount of energy produced de- pends on the volume evacuated and the pressure difference produced.

mechanical vacuum pumps use the same pumping mechanism as air compressors, except that the unit is installed so that air is drawn from a closed volume and exhausted to the atmosphere. A major difference between a vacuum pump and other types of pumps is that the pressure driving the air into the pump is below atmospheric and becomes vanish- ingly small at higher vacuum levels. Other differences between air compressors and vacuum pumps are:

• the maximum pressure difference produced by pump action can never be higher than 29.92 in. Hg (14.7 psi), since this represents a perfect vacuum.
• the mass of air drawn into the pump on each suction stroke, and hence the absolute pressure change, decreases as the vacuum level increases.

technical specification:

available range 1.5hp to 15hp with air receiver and base mount model

Columbia Pet Compressor Series 2 reciprocating air compressors offer durability and reliability combined with energy savings. Standard PET reciprocating compressors feature two-stage compression. Columbia maximizes efficiency with two stages of compression, which significantly increases efficiency over single-stage designs. Combined with industrial grade components and double-acting cast iron cylinders, Columbia PETAIR compressors provide supreme durability that reduces maintenance requirements and lowers lifecycle costs.

Columbia borewell water lifting compressor pump for agriculture, factories, housing complexes, domestic and for many more applications with a simple method. Compressor pressure lift the water from 150 feets to maximum 950 feets . These pumps are suited for continuous operations with a low power consumption. Special type compressor also available (Double bed type)
