The Sanifos ZFS is a powerful pumping station with one or two Sanipump ZFS 71 macerator pumps for for underfloor installation (below ground) outside of buildings. These pumping stations dispose of grey water and blackwater from single-family homes, apartment blocks, public and commercial buildings and can be used as drainage pumping stations or for pressure drainage. They are buoyancy-proof up to a maximum groundwater level of 120 cm from the bottom edge of the shaft. The PE-LLD prefabricated shaft has a volume of 1,600, 2,100 or 3,100 litres and can be height-adjusted using an optional, adjustable top section. For these models, shaft covers are available in BEGU classes A, B or D. The pressure pipes and ZFS 71 macerator pump(s) with coupling system and removal chain are pre-assembled in the shaft. There are 5 macerator pumps of different performance classes available. The maximum discharge head is 39 m, the pumping capacity 17 m³/h. The pumping stations have a DN 100 side inlet and 2 further DN 100 connections for ventilation and cable entry. The waste water is discharged through a DN 50 pressure pipe outlet. The scope of delivery includes a non-return valve, pneumatic control ZPS1 or ZPS2, connection accessories and a connection cable. A float control is available as an option. Available in over 90 different configurations – optimally matched to your individual project.
