3.4 Design and operating mode
The pumping station is equipped with several horizontal and vertical inlet openings for 40/50/100/110/125 mm external diameter piping
The motor-pump assembly conveys the pumped fluid in the discharge pipe with an external diameter of 50 mm (DN 40) in maceration
version or external diameter of 63 mm (DN 50) in vortex.
The ventilation duct (external diameter 75 mm) allows the tank to always remain at atmospheric pressure (2 ventilation holes are avai-
lable on the SANIFOS
®
250 and SANIFOS
®
500 and 1 ventilation hole on the SANIFOS
®
110 pumping station).
3.4.1 SANIFOS
®
110 and SANIFOS
®
250
Operating mode:
Effluents enter the pumping station
through the horizontal and vertical
inlet openings.
They accumulate in a gas-tight,
smell-proof and watertight plastic
tank.
As soon as a certain fill level is
detected by the float switch, the
pump starts up automatically.
Effluents are automatically raised up
to flow into the drain pipe.
As soon as the effluent level reaches
a minimum effluent level in the tank, detected by the float switch, the pump switches off automatically.
3.4.2 SANIFOS
®
500
Operating mode:
Effluents enter the pumping station through the horizontal and vertical inlet openings.
They accumulate in a gas-tight, smell-proof and watertight plastic tank.
When the effluent enters the tank, the low float rises and then the high float rises to
reach the pump's activation level.
The pump starts up and the effluents are lifted automatically to flow into the drain pipe.
As soon as the effluent level reaches a minimum effluent level in the tank, detected by
the low float switch, the pump switches off automatically.
SANIFOS
®
500 contains 2 pumps that operate alternately. In case of malfunction, the
alarm is triggered by the alarm float and the 2 motors operate simultaneously.
If one of the 2 pumps is defective, the other one takes over.
