The FPS-K single and dual unit is a powerful pumping station with one or two ZFS 71 macerator pumps 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 n aoption. Available in over 90 different configurations – optimally matched to your individual project.
