* Circulating pump: A circulating pump is used to move a fluid through a closed loop. The symbol for a circulating pump is a circle with an arrow indicating the direction of the flow.
* Submersible pump: A submersible pump is used to move a fluid from a well or other submerged location. The symbol for a submersible pump is a circle with a downward-pointing arrow.
* Reciprocating pump: A reciprocating pump is used to move a fluid by means of a piston or diaphragm. The symbol for a reciprocating pump is a rectangle with two vertical lines representing the piston or diaphragm.
* Centrifugal pump: A centrifugal pump is used to move a fluid by means of a rotating impeller. The symbol for a centrifugal pump is a circle with a curved arrow indicating the direction of the flow.
Electrical Schematic Symbols for Heat Tracing
* Heat tracing cable: Heat tracing cable is used to maintain a specified temperature in a pipe or other object. The symbol for heat tracing cable is a line with alternating dashes and dots.
* Heat tracing controller: A heat tracing controller is used to control the temperature of a heat tracing cable. The symbol for a heat tracing controller is a rectangle with a downward-pointing arrow.
* Heat tracing termination kit: A heat tracing termination kit is used to connect heat tracing cable to a power source. The symbol for a heat tracing termination kit is a rectangle with two downward-pointing arrows.
