Design Multistage, self-priming pump in close-coupled design with axial fluid inlet and
vertical fluid outlet.
The hydraulic system runs in common bearings and is connected to the motor via a
shaft.
Sealing The pump is sealed by a standardised mechanical seal. A thrower protects the
bearing and the motor in the event of leakage.

Function of The fluid enters the pump via the suction nozzle (1) and is accelerated outward by
Multi Eco the rotating impellers (5). In the flow passage of the diffusers (6) and the pump
casing the kinetic energy of the fluid is converted into pressure energy. The fluid is
pumped to the discharge nozzle (2), where it leaves the pump. At the rear side of the
impeller, the shaft (3) enters the casing via the discharge cover (7). The shaft passage
is sealed by a shaft seal (4). The shaft runs in rolling element bearings.

Phase No. 1:
When the consumer installation is closed, the pump is stopped. The green "Power"
indicator lamp of Controlmatic E.2 is lit.
Phase No. 2:
When the consumer installation is opened, the water pressure in the system
decreases. The pump is started up.
Phase No. 3:
The pump is running, the yellow "On" indicator lamp is lit.
Phase No. 4:
When the consumer installation has been closed and the flow rate is zero, the pump
is stopped after 10 seconds. The pump is protected from dry running by simultaneous
pressure and flow monitoring. If there is a lack of water, Controlmatic E.2 stops the
pump and the red indicator lamp is lit.

3 Pressure gauge
Function of When the system pressure drops, the pump (1) is automatically started via the
Multi Eco-Top pressure switch (3). When the required pressure has been reached, the pump is
stopped automatically.
The membrane-type accumulator (2) serves to limit the frequency of pump starts by
providing smaller amounts of water from the volume stored.
