Hydrophore (pressurisation tank) is a pumping system with cylindirical tank which raises the low-pressured-water to the required height by pressurizing with air and operates automatically. Hydrophore systems are used to fulfil the water requirement of multi-floored buildings when the water supply network of the province is inadequate. The hydrophore and water tank are used individually as well as they are fixed jointly in some facilities. Pressurization process is performed by tank, pump and auxiliary fixtures on them.
