Though these words may be used interchangeably, there is a difference. A pump is a motor designed to move fluids (whether gas or liquid). A compressor is a kind of pump that has a motor that forces air molecules closer together to pack more matter in a smaller volume. Gases are the only things that are compressable where pumps deal more with liquids (mainly water) although there are air pumps.

Pumps are used to move liquids of all kinds not just water. They can be driven by electric motors, steam turbines, wind power etc. Compressors move gasses.
We sometimes use what is called a tire pump to inflate bicycle tires but it is actually a hand powered compressor.

∙ 10y agoReciprocating and centrifugal pumps serve different purposes and operate with separate functions. Centrifugal pumps transport huge amounts of liquid at a time, but the level at which the centrifugal pump operates is reduced as pressure rises. Reciprocating pumps push liquid out through a check valve, but the amount of liquid that is released is limited. Due to the differences in how they operate, they are ideally suited for dissimilar functions.

What is the difference between a single acting reciprocating pump and a double acting reciprocating pump?
it runs without fluctuation i.r continuous flow......
What is the difference between centrifugal compressor and screw compressors?
A rotary compressor is like a car engine, with pistons, rods, sleeves, valves, etc. A screw compressor has two screw type rotating parts that squeeze the refrigerant as the screw threads get tighter and tighter. They have long life potential.
How does a windmill pump water from the ground?
As the reciprocating pump operates though the reciprocation of the follower,it guides the suction and the compression of water in the pipe.That's so when the rotary motion of the rotor blade is converted into the reciprocating motion, which deliver it to the reciprocating pump, the suction and discharge takes place.
Define the term negative slip in reciprocating pump?
When the actual flow (Qa) is greater than theoretical flow (Qt) in a reciprocating pump it is negetive slip.
What is difference between vacuum pump and centrifugal pump?
A compressor is a piece of equipment that compresses gas either to transfer to a specific location or for a certain process requirement. Compressor are manufactured depending on application and can be class into two basic types; positive-displacement and centrifugal. Integrally geared centrifugal compressors can operate at many times higher speeds than reciprocating compressors. The higher speeds ultimately result in smaller package sizes, requiring a smaller footprint as compared to a reciprocating compressor. The operating speed of a reciprocating compressor is very slow due to mechanical and dynamic limitations. Furthermore, the lower speed of reciprocating compressor lends itself to larger compressor size, heavier weight, and larger plot plan size. Whereas the centrifugal compressor with higher operating speeds results in smaller overall compressor package sizes such as smaller gearing, bearings, seals, lubrication system, and foundation. Smaller packages ultimately lend themselves to saving in lower overall installations as well as lower capital and spare parts costs. Higher reliability is fully attainable with centrifugal compressors. The rotating aerodynamic components (impellers) have no physical contact with the stationary parts (inlet shroud). On the contrary, the reciprocating compressor moving components such as the piston and valves are physically in contact with the cylinder and other stationary components during operation. The physical contact causes wear and tear of both moving and stationary components, which requires constant maintenance. However, a centrifugal compressor operates for many years with continuous service without overhaul maintenance, resulting in less power plant down time. This eliminates loss of product, provides more profit, lowers risk, and results in lower maintenance cost. Overhaul periods are more predictable by analyzing characteristic efficiency and vibration trends. A typical centrifugal compressor overhaul inspection period is more than 7 years as compared to less than 2 years for most reciprocating compressors. In addition to the economical advantages of implementing a centrifugal compressor over a reciprocating compressor, many technical advantages are also evident. The centrifugal compressor discharge pressure can be regulated to less than 0.5% per second. The well-regulated compressor discharge pressure provides very steady supply of fuel to the gas turbine. This is an advantage since it does not cause additional burden to the turbine controls. On the other hand, a reciprocating compressor at best can provide 2% or more of pulsating pressure. Unsteady supply of fuel may cause hardship on the turbine control system. A reciprocating compressor would require an impractically over-sized pulsation bottle to minimize supply pressure pulsation to the level as steady as a centrifugal compressor. Considering there is no physical contact between the centrifugal compressor aerodynamic components, the need for lubrication within the compression components is not required; thus it will not add oil or other contaminants to the process gas. However, a reciprocating compressor requires oil lubricant for the piston rings. This oil eventually ends up in the process gas or it has to be separated to protect the gas turbine. Due to physical contact between the piston rings and the cylinder, the wear of the rings and packing causes particle contamination of the fuel gas. Hence, this contamination could cause premature wear on the turbine blades and other turbine fuel gas passages

What is the difference in a pump and compressor?
they have different names A Pump is a mechanical device which transfers Liquid from a lower point to a higher point.Eg: Centrifugal pump,Rotary pump,Reciprocating pump. A Compressor is a high pressure mechanical device which basically compressors air/gas Well, a compressor compresses a gas and a pump moves a liquid. Compressors are often used in refrigeration applications where gas is transformed into a liquid and vice-versa, so the main task for the compressor is not to move the gas but to compress it.
What is difference betweenrotar of centrifugal pump and compressor?
pump is used to handle liquid and compressor is used to handle gases. other difference include blade shape etc..
What is the difference between pumps and compressor?
pump is used to move liquid from one point to another, while compressor is used to compress and move gases from point to point.
What is the difference between centrifugal compressor and screw compressors?
A rotary compressor is like a car engine, with pistons, rods, sleeves, valves, etc. A screw compressor has two screw type rotating parts that squeeze the refrigerant as the screw threads get tighter and tighter. They have long life potential.
Difference between compressor and pump rotor?
The only one difference in b/w compressor and pump rotor is impeller shroud width.Fluid is incompressible so impeller shroud width is not change and gas is compressible so impellers are tends to thin in width to the discharge side.
What are the parts of refrigeration compressor?
The parts of a hermetic (sealed) reciprocating compressor is as follows; motor, crankshaft, bearings, valves, and pressure relief valve and piston(s). there are other smaller parts that can be named but these are the main players. The hermetic scroll compressor is a little different than the reciprocating compressor because it uses an orbiting scroll and a stationary scroll to compress the refrigerant instead of pistons. This is why a scroll compressor cannot run "backwards". The scroll compressor also has an oil pick up tube which differs from a reciprocating compressor. Now a "semi-hermetic" compressor is build like a small engine. It has an oil pump, reed valve plate, unloaders, pistons, bearings, etc. A screw compressor is in a class all to itself.
If the outlet valve for both centrifugal and reciprocating pump is closed which pump is damage first and why?
The reciprocating pump is damaged first. The closed outlet has no bad affect to the centrifugal pump.
What are the advantages of a reciprocating pump?
we can pump water in high current
What is difference between fuel pump relay and compressor relay?
Pump relay is used to increase the pressure of incompressible fluids (i.e., density is constant for change in pressure) Compressor relay is used to compress the pressure of compressible fluids (i.e.,density varies with pressure)
Is receiprocating pump advantageous or centrifugal pupm?
A reciprocating pump is an advantageous pump. Centrifugal pumps convert energy into rotation to power themselves. A reciprocating pump uses a back and forth linear motion.
How does a windmill pump water?
As the reciprocating pump operates through the reciprocation of the follower, it guides the suction and the compression of the water in the pipe. That's so when the rotary motion of the rotor blade is converted into the reciprocating motion, which delivers it to the reciprocating pump, the suction and discharge takes place.
