Kerosene - a mixture of liquid hydrocarbons obtained by distilling petroleum, and is commonly used as fuel or cleaning solution. Also spelled as kerosine.
Kerosene is sometimes used as a medium for secondary hydrostatic testing of pumps used in very low specific gravity service after the pumps are hydrotested with water to verify that the casings will not leak when handling low specific gravity liquids.

Key - a small piece of square or rectangular metal used to lock a rotating part - such as an impeller, coupling, or sleeve - with a shaft, and to transmit force to cause that part to rotate with the shaft without any slippage. Read more.
