Centrifugal pump FZ series

waterwith electric motorsubmersible

Application Type FZ impeller single-stage pumps are used to pump clean and dirty water, municipal and industrial waste, as well as other liquids, depending on corrosion resistance of materials of which the pump is made. They constitute a highly-unified family of submersible and dry-installed pumps. There are different versions of these pumps, depending on the characteristics of pumped liquids and the type and size of pumped impurities. In particular, they are applied in the pumping of sewage, including sewage with solid and long-fibre content, as well as liquids containing air and gases. They will work very well in pumping of raw sewage containing active sediment, and putrid sewage. The FZA type pump is equipped with a multi-vane one-side open impeller for pumping water, liquid manure solutions, faeces, contaminated liquids, gassing liquids without abrasive precipitations having a diameter larger than 6 mm, and fibrous impurities. There are no internal motor safety devices in the FZA pumps. The drive motor in the FZA pump is "wet" – it is filled with white mineral oil according to the PN-60/M-96105 standard. The pump is only available as FZA.1. The FZB type pumps are equipped with a closed channel impeller. The pump is used for pumping contaminated liquids with solid and sewage content (e.g. water with sand) and without fibrous substances. The characteristics of these systems: high efficiency of the hydraulic system; less “free” passage as compared to Vortex systems. The pumps of this type are used in sewage pumping stations with seperation of solids manufactured by Hydro-Vacuum SA, but they can also be used for pumping other liquds than preliminarily cleaned sewage.
