Structural Features
1

Float
The float sustains a submersible pump
by buoyancy at an appropriate position.
Made of fiber reinforced plastic (FRP),
the float is filled with polystyrene foam
which prevents the loss of buoyancy in
case the float is broken.

Intake Check Ball
A check ball incorporated in the intake
closes the suction mouth by buoyancy
when the pump stops operating thus
preventing the inflow of floating sludge.
During operation, the ball is sucked in by
the pump’s suction power to take in
supernatant liquid.

Anti-sludge Sensor
When the amount of light transmitted
from an emitter via glass fibers is
reduced by a certain density of sludge
existing in the liquid, the sensor identifies the light amount and sends corresponding signals to the control panel to
stop or operate the pump not to suck up
sludge.

6

Sensor Cleaner
The sensor cleaner spouts a jet of clean
water from its nozzle to wash the light
emitter and receiver at fixed intervals.
The pressurized water can be treated
water coming from a submersible pump
installed in the spray pump tank.

Recommendation;
• The washing shall be performed for 5
minutes every 1.5 hours during the
aeration process.
• The amount of washing water shall be
regulated with a valve over a range of
10 to 20 L/min and the pressure, 0.5 to
1 kg/cm2.

Each component, such as dual inside
mechanical seal, motor protector, and
anti-wicking cable entry, represents
Tsurumi’s outstanding expertise.
