Galvanic corrosion occurs when a corrosive electrolyte and two metallic materials are in contact. This corrosion increases on the least noble material (the anode) and decreases on the noblest (the cathode).
The simple gear pump consists of two spur gears meshing together and revolving in opposite directions within a casing. Any liquid that fills the space between the gear teeth and the case must follow along with the teeth as gear turn.
Gas extinguishing systems
Gas extinguish systems have gas stored in self contained bottles, and when activated the gas reduces the oxygen levels to below the percentage needed for combustion or create a chemical reaction to break the “fire triangle” (heat, fuel, oxygen).
GENIbus is an open data communication protocol developed and maintained by Grundfos. It is used to connect Grundfos pumps to pump controllers or via gateways to monitoring and supervisory computers in Building Management Systems and SCADA systems.
