How to design safe, reliable fire pump power service

Mar 24, 2016 · The fire pump plays a critical role in providing for a safe environment, and how it is powered is an important consideration of the design. A reliable source, backup power supply, protected feeders, and properly sized overcurrent protection are the keys to a successful installation.

Why prefabricated pumping stations are the right choice

A PS.G pumping station is made of corrosion-free glass-fibre reinforced polyester, exceeding the lifetime of a traditional concrete pumping station by far. With a diameter of 1200 to 3000mm it can provide a much larger amount of space than the PS.R and therefore it is also prepared for bigger pumps, highlighting one of the main differences
