Lifting Station Type ABS Nirolift. Lifting Station Type ABS Sanisett.
1 General
1.1 Description
The wastewater lifting stations Nirolift and Sanisett consist of a synthetic collection tank which is waterproof in
accordancewithEN12050-2,togetherwithacoverplatewithodour-preventinglterandlockableoorinlet.
The Sanisett is supplied with a junction piece for the discharge line and a bracket for the level control.
The collection tank is supplied as standard with a number of closed-off inlet ports. The inlet ports DN 100
(Nirolift) and DN 100/150 (Sanisett) can be opened as required (see Figure 3).
The wastewater entering via the inlet ports is collected in the collection tank. When a preset liquid level is
reachedthenthesubmersiblepumpisstartedupeitherbymeansoftheoatswitchttedtothepumpitselfor
connected into the control panel, and is switched off again when the tank is emptied.
NOTE: In the case of twin units installed in accordance with EN 12056, one submersible
pump must be capable of pumping all the efuent. The second pump is only a
stand-by unit.
1.2 Application areas
Synthetic, prefabricated, corrosion-resistant sump for Sulzer submersible pumps, designed for the automatic
pumping of wastewater in accordance with EN 12056 from locations and areas below the backwash level.

This product is only suitable for removing clear and dirty water up to a water temperature of 40 °C or
up to a maximum of 60 °C during short-term operation.
If the system is fed water from units such as washing machines, then the maximum water temperature
could be exceeded if the device is not equipped with discharge cooling or if this is not switched on,
e.g. in order to save energy.
This may cause damage to the pump or the pumping system. In such case Sulzer will not accept any
guarantee or warranty claim.
If necessary, contact the manufacturer of the device or devices provided for connection (e.g. washing
machines) to obtain information on how to switch on discharge cooling.
Our systems are checked in accordance with EN 12050 LGA and conform to the current standards.
Also note that the maximum inlet temperature to the public sewer system is 35 °C and that you must
ensure that the water is cooled accordingly.
