EMUPORT-PEHD underground pumping
stations with pumps installed in dry sump and solids separation system
The pumps do not come into contact with the solids in the sewage itself during the pumping process. This results in the following advantages:
– low maintenance and operating costs for moving parts of the pumps
– pump compartment remains dry, clean and odor-free
– hygienic conditions for maintenance and assembly work
– can be equipped as double pumping station; the plant remains fully functional, even when a pump is being serviced

– WILO submersible sewage pumps with suitable impeller
– no corrosion problems, no consequences in case of formation of sulfur
– Application of pumps with ball passage < 80 mm, therefore little power requirement with higher efficiency
– Less wear
– WILO Sewage Pumps with protection type IP 68 (submersible)

Reliable Sewage Transport
Wherever municipal and industrial sewage is produced, it must be collected and transported to the sewage treatment plant.
PEHD-EMUPORT underground pumping stations with PEHD pit (alternatively with concrete pit) are most suitable for this problem. They operate reliably and moreover offer highest possible protection against corrosion.

Functioning
With this system, the incoming sewage enters the distribution reservoir and then flows into the respectively open solids separation reservoir. Here, the solids are held back by separating flaps. The solids are »filtered out». Only the »thin» sewage can now continue through the pump into the large joint collection reservoir. When the collection reservoir is being filled, the water level in the solids separation reservoir also rises. The shut-off ball automatically closes the inlet.
The pumping process now begins in accordance with the level. The pump operates in the reverse direction and opens the separating flaps with the volume flow of the »thin« sewage. The sewage flows through the solids separation reservoir and transports the solids »filtered out« of the sewage to the outgoing discharge pipeline. The entire solids separation system is flushed out and cleaned.
The pumping process is also ended in accordance with the level. The shut-off ball falls down and clears the way for a new filling process. The sewage is routed to the other solids separation reservoir during this pumping process.

The low operating costs result from the use of pumps with small ball passage, as they require less motor power.
