Wastewater pumps series 8000

Wastewater pumps series 8000
Flygt 8000 series, a complement to the Flygt range of waste and process water pumps
The 8000 series vortex pumps broaden the product range of waste and process water pumps up to 80 m head and 130 l/s in flow.
In a vortex pump, flow is produced not by the actual impeller but by a rapidly rotating vortex that is created by the impeller. This kind of pump offers two major advantages, and one disadvantage. Because the pumping action is produced by the vortex, solids in the liquid do not come into contact with the impeller itself, thereby minimizing wear. A second advantage is the open design of the volute: positioned high on the roof of the volute, the impeller takes up very little space which leaves a large area through which sizeable solids can freely pass. On the minus side is efficiency. Precisely because the volute is so open, the hydraulic losses are much greater in comparison with shrouded channel impellers.

The 8000 series includes:
- A full range of dry pumps
- A number of pumps in stainless steel (both dry and submersible) for handling corrosive media
- A range of wear resistant pumps, both dry and submersible, for continuous transportation of highly abrasive solids
- Finally a number of submersible pumps in cast iron, acting as "performance gap fillers" in the existing series of vortex pumps.

C & D 8000 series dry-installed vortex pumps
Why dry-installed pumps?
· Pumps have hardly any influence on solids entering the suction pipe ((Not sure what is meant here. How about: Pumps are virtually unaffected by solids entering the suction pipe))
· Easy installation
· Easy maintenance
· In larger sewage treatment plants, the cost of the infrastructure often justifies using dry-installed
pumps
• This can also be the case for pump station

D 8000 series corrosion-resistant vortex pumps 
• This range of corrosion resistant pumps is one of the most reliable and cost effective on the market.
• Available for submersible or dry installation
• Vortex technique with large throughlet handles large solids without risk for blockages

H 8000 series wear-resistant vortex pump
· Available for submersible or dry installation
• Besides very good solids handling properties, the vortex technique is by nature low in wear, resulting in minimum downtime and high long term performance
• Designed for continuous transportation of highly abrasive solid
