Questions About Our Resources
What is the electrical symbol for ground?
Connection to the actual ground or other “grounding” structure. Used to provide electrical shock protection and for zero potential reference.
What is the symbol for voltage?
Check out our electrical symbol guides for transformers and selectors.
What is the symbol for voltmeter?
Very high resistance device used to measure electrical voltage. Must be connected in parallel.
What are the electrical symbols?
Our industrial electrical symbols guide helps you correctly identify components and prevent potential hazards during pump installation.
What is the symbol of switch?
"NO (Normally Open): The “normal” state for a switch is its non-actuated position. Depending on its construction, a switch’s normal state can produce an open circuit or a short circuit. When open until actuated, a switch is a normally open (NO) switch; when activated, a NO switch closes the circuit.
NC (Normally Closed): Essentially the “opposite” of an NO switch. A switch that creates a short circuit when not actuated. Normally closed (NC) switches create a short circuit when actuated."
What is the symbol for a meter?
Check out our electrical symbol guides for transformers and selectors.
What is the symbol for amperage?
Zero resistance device used to measure electrical current. Must be connected serially.
Where can I find a guide to aodd pump operation?
With straightforward AODD pump designs, Wilden makes industrial pump maintenance easy. If your pump is experiencing difficulties with functionality or pumping processes, Pumping Solutions recommends these actionable steps to repair your pump and resume operations.
What is surge suppressor?
Surge suppressors help smooth product flow and reduce the "hammer" effect that AODD pumps are known for. By reducing this effect, you can greatly increase the life of your pump.
What is the symbol of transformer?
Check out our electrical symbol guides for transformers and selectors.
What is air filter regulator?
Pumping Solutions offers a full line of Filter Regulators for your Air Operated Pump needs. Sizes ranging from 1/4" to 3/4". Some units even come equipped with an inline lubricator. Don't leave your pump unprotected!
Which of these is the symbol used for an spdt switch?
A switch utilizing three terminals: one common pin, two pins vying for connection to the common (only one can be connected at a time). Ideal for selecting between two power sources or swapping inputs. Can be made into an SPST switch by simply leaving one of the throw pins unconnected.
What is the symbol of circuit breaker?
Automatically operated electrical switch that protects electrical circuits from damage caused by short circuits or overloads.
What represents a closed switch in a circuit?
NC (Normally Closed): Essentially the “opposite” of an NO switch. A switch that creates a short circuit when not actuated. Normally closed (NC) switches create a short circuit when actuated.
Which of these symbols represents a fuse in an electrical diagram?
Sacrificial overcurrent protection device. This symbol represents low power/low voltage fuses.
