A circle with a triangular wedge, marking a pump and its flow direction.
Also known as: Pump symbol, Circle with a triangle
A circle with a wedge marks a centrifugal pump. The wedge points the way the fluid leaves, so the symbol carries direction as well as identity — which matters because a pump installed backwards does nothing.
Marks a centrifugal pump on a process or piping diagram, with the wedge indicating the direction of discharge.
Contexts: Technical drawing
Distinguishes pump types by the internal drawing: a wedge for centrifugal, a piston or gears for positive-displacement types.
Contexts: Technical drawing
A circle with a triangular wedge inscribed inside it, its apex at the circle's centre and its base at the discharge side, with pipe lines meeting the circle at inlet and outlet.
Pumps and valves are the two commonest elements of any process diagram.
