KSB Leakage Sensor
1984.8/02-EN
5.3.1 Installing a KSB Leakage Sensor that has been supplied but not fitted
ü The operating manual for the pump (set) is available.
ü Assembly tools are available.
ü All safety instructions have been observed and carried out.
ü The pump (set) has been taken out of service and secured against unintentional
re-start.
ü The pump (set) has cooled down to room temperature.
1. Position sensor housing 105 on a level surface next to the pump, e.g. on the
baseplate of the pump.
ð Select a sensor housing position that keeps the line leading from the pump
to the sensor as short as possible.
ð Select a sensor housing position that keeps the distance to any hot pump
components and system components as large as possible.
ð If the leakage inlet 8E is positioned on the same side as the leakage drain 8B,
the upper half of the sensor housing can be taken off, rotated by 180° and
mounted in this position. (ðSection7.3.2,Page25)
2. Mark the position of the drilled holes at the two lower recesses of sensor
housing 105 on the pump baseplate.
3. Carefully place aside sensor housing 105. Drill holes (M5) into the pump
baseplate.
4. Position the sensor housing again. Fasten it to the pump baseplate with
hexagon socket head cap screws 914.2.
5. Verify the levelling of sensor housing 105 with measuring instrument 690
(bullseye level). If necessary, undo hexagon socket head cap screws 914.2 and
level the sensor housing with suitable shims. Re-tighten hexagon socket head
cap screws 914.2.
6. Use the supplied compression fittings and L-pipe to connect the leakage drain
hole of the pump (set) with leakage inlet 8E of the sensor housing.
ð If necessary, shorten the leakage line (pipe) accordingly.
7. Use the supplied compression fittings and L-pipe to connect the leakage drain
hole 8B of the sensor housing to the site-supplied leakage collector.
ð Fit the leakage line with a continuously falling slope towards the site-
supplied leakage collector.
5.3.2 Installing a pre-mounted KSB Leakage Sensor
ü The operating manual for the pump (set) is available.
ü Assembly tools are available.
ü All safety instructions have been observed and carried out.
ü The pump (set) has been taken out of service and secured against unintentional
re-start.
ü The pump (set) has cooled down to room temperature.
1. After the pump set has been installed, verify the levelling of sensor housing 105
with measuring instrument 690 (bullseye level). If necessary, loosen hexagon
socket head cap screws 914.2 and level the sensor housing with suitable shims.
Re-tighten hexagon socket head cap screws 914.2.
2. Use the supplied compression fittings and L-pipe to connect the leakage drain
hole 8B of the sensor housing to the site-supplied leakage collector.
ð Fit the leakage line with a continuously falling slope towards the site-
supplied leakage collector.
