The method used to move the air, and by the system pressure they must operate against fans, blowers and compressors are differentiated. Fans, blowers and compressors are differentiated by Fan and blower. The selection of fans and blowers depends on the volume flow rate, pressure, type of material handled, space limitations, and efficiency.

Blowers can achieve much higher pressures than fans and are used to produce negative pressures for industrial vacuum systems. The two major types of blowers are: centrifugal blower and positive displacement blower.

Centrifugal blowers look more like centrifugal pumps than fans. The impeller of a centrifugal blower is gear-driven which rotates at 15,000 rpm. In multi-stage blowers, air is accelerated as it passes through each impeller. In single-stage blower, air does not take many turns, and hence it is more efficient.

Centrifugal blowers usually operate against pressures of 0.35 to 0.70 kg/cm2, but they can also achieve higher pressures. In centrifugal blower airflow tends to drop drastically as system pressure increases, which can be a disadvantage in material conveying systems that depend on a steady air volume and hence used in applications that are not prone to clogging.

Positive-displacement blowers have rotors, which “trap” air and push it through housing. Positive-displacement blowers provide a constant volume of air even if the system pressure varies. They are especially suitable for applications prone to clogging, since they can produce enough pressure – typically up to 1.25 kg/cm 2 – to blow clogged materials free. They turn much slower than centrifugal blowers (e.g. 3,600 rpm), and are often belt driven to facilitate speed changes.

Industrial blowers can be specified by blower type, flow capacity, dimensions, maximum operating pressure, port design and electrical ratings. Some of the applications where centrifugal blowers are used, are for combustion air suppliers, drying and cooling systems and for dust control, air conveyor systems, fluid bed aerators etc.

Positive displacement blowers are used mostly for sewage aeration, in pneumatic conveying, gas boosting, filter flushing and all kinds of petrochemical industries.

Pumps are devices that move fluids by mechanical action, from one place to the other. Pumps are classified into two types: Dynamic and Positive Displacement.

Dynamic pumps are further classified as: Centrifugal pumps, Vertical centrifugal pumps, Horizontal centrifugal pumps, Submersible pumps and Fire hydrant systems

Positive Displacement is further classified as Diaphragm pumps, Gear pumps, Peristaltic Pumps, Lobe pumps and Piston Pumps.

Centrifugal pumps are the most used pump type in the world, due to simple working principle and relatively inexpensive manufacturing cost.

American Blower LLC provides services for any brand or manufacturer of pumps. Our services range from standard inspections and repairs to complete overhauls. A repair or overhaul of a pump generally consists of an inspection and repair/modification. Some of the key players operating in the global industrial blowers market are Gardner Denver Inc., Hoffman & Lamson, SPX and others. While in pumps Nash, Gardner Denver, Hoffman & Lamson, Sutorbilt, and Roots among others contribute to the major share in the market.

We rebuild all types of pumps and blowers to bring its operation back to OEM specifications. The technicians have been factory trained in the process of vacuum pump repair. After the repair or remanufacturing process is complete, each item is system tested to ensure proper operation, OEM specification verification, and extended operation under load and also with stocks of spares to support older or obsolete equipment which OEM no longer supports. We use only OEM parts for repairs to ensure the highest quality of work and extend the life of your equipment. You can repair, rebuild, or exchange your pump with our replace program.

Please contact us for all your requirements on blowers or pumps call us (713) 360 6995 or mail us at info@americanblowerllc.com. We are based in Houston, Texas and our skilled technicians will address all your queries.
