2.2 Control and monitoring
The pumps can be controlled via the Grundfos controllers LC,
LCD 107, LC, LCD 108, LC, LCD 110 and DC, DCD.
Pumps with a sensor are supplied together with an IO 111 or
IO 113 which can receive signals from the following transmitters:
• water-in-oil-sensor (WIO sensor) in the pump
• moisture sensor in the motor
• temperature sensor in the stator windings
• winding resistance sensor in the motor.
For further information, see installation and operating instructions
for the specific sensor.

2.3 Applications
SE1 and SEV pumps are designed for pumping these liquids:
• large quantities of drainage and surface water
• domestic wastewater with discharge from toilets
• wastewater with a high content of fibres
(SuperVortex impeller)
7
• industrial wastewater
• wastewater with gaseous sludge
8
• municipal and commercial sewage and wastewater.
SE1 and SEV pumps are ideal for installation in locations such
as:
• public buildings
• blocks of flats
• industry
• garages
9
• multi-storey car parks

Stainless steel versions
Stainless steel versions are further more suitable for the following
applications:
• industrial process water containing chemicals
• aggressive or corrosive drain water and effluent
• abrasive particles in wastewater
• wastewater contaminated with seawater.
The compact design makes the pumps suitable for both
temporary and permanent installation.
