Definition: Immission (from Latin immittere = “to send in”) is used in environmental law as a term for any impact on the environment and includes the impact of dirt, but also noise, radiation and other influences. In the industrial environment, this exposure to disruptive factors has an impact on humans and the environment. For all immissions, therefore, limit values and guide values are applied to ensure that there are no harmful effects on humans, soil, air and water, animals and plants. Examples of potentially harmful immissions are

• air pollution,
• noise,
• vibrations,
• radiation and
• chemicals.

Immission-relevant properties of pumps are mainly operating noise and leakage. For example, noise protection must be taken into account when operating pumping systems; if pumps convey toxic media, it must be ensured that leakages are reduced to a minimum and that escaping fluids cannot get out into the environment in an uncontrolled manner.
