What are the two types of pumps in compressors?

Answer: The two different types of pumps in compressors are:

1) Centrifugal Pumps

2) Reciprocating Pumps

Explanation:

Compressor is defined as a mechanical device which increases the gas pressure by reducing its volume. The main action of a pump is to transport liquids and pressurize and it coverts rotational energy. As, centrifugal pumps are the most common pumps used for transfer of fluids and it works on simple mechanism.

Reciprocating Pumps is used for low volumes of flow at a high pressure. It is the positive displacement pump. As, it works on the principle of pushing of liquid which executes a reciprocating motion in a closed cylinder.

Centrifugal Pumps and Positive Displacement Pumps

Explanation:

The two of pumps listed above is based on the mode of operation. The centrifugal pumps works by increasing the velocity of the liquid through the machine while the displacement pumps works by alternating, filling a cavity and then displace some amount of liquid.
