Process and Instrumentation Symbols - Equipments

Pumps and tanks come in a variety of designs and shapes.

Pumpsis a mechanical device using suction or pressure to raise or move liquids, compress gases, or force air into inflatable objects such as tires. The symbols for pumps may closely resemble those for compressors.

Centrifugal pumpis rotodynamic pump that use a revolving impeller to add to the force and pressure of fluids.

Gear pumpprovide continuous, non-pulsing flow making it ideal in chemical installations.

Sump pumpis widely used to remove accumulated water from a sump pit or other location.

Vacuum pump is used to improve the efficiency of steam heating systems in many ways. The most important consideration is the rapid and efficient removal.

Screw pumpis the Archimedes screw pump that is still used in irrigation and agricultural applications.

Tank

is used to store process fluids of various types, under different process conditions.

Onion tankis an open top collapsible bladder designed for use as a mobile storage solution when recovering contaminants.

Compressoris a mechanical device that takes in a medium and compresses it to a smaller volume. A mechanical or electrical drive is typically connected to a pump that is used to compress the medium.

Axial compressoris widely used in gas turbines, such as jet engines, high speed ship engines, and small scale power stations.

Reciprocation compressoris typically used where high compression ratios are required per stage without high flow rates, and the process fluid is relatively dry
