Pressurization Group (VERTICAL TURBINE PUMPS)

Complies with the standards: UNI EN 12845/15 – UNI 11292 – UNI 10779

Pressurization group for fire-fighting service with vertical axis pumps pre-assembled on a single or modular base and with immersed pump body, shaft line and surface control group compliant with EN 12845. The pumping groups installed inside the technical spaces , are made in compliance with the UNI EN 12845 regulation and are complete with every accessory capable of making the entire system intervene automatically if water supply is requested. In standard setups the groups can be made up of one or more electric or diesel pumps (main pumps) and a pilot compensation electric pump.
