4. INSTALLATION:

4.1. PUMP INSTALLATION IN THE RESTING
POSITION (TANKS):
- The pump can be rested on the flat botton surface of
a tank, but when sand or particles of sediment are
present it's advisable to mount the pump on a surface
raised from the bottom level so that abrasive matter is
not lifted.
4.2. PUMP INSTALLATION IN THE
SUSPENDED POSITION (WELL):
- The pump can be held in a suspended position by the
metal delivery pipe.
- Tighten the threaded pipe joints firmly to avoid
loosening during operation.
- Position the pump at a distance of at least 0.5m from
the bottom of a well so that sand is not lifted (fig. 1).
- When a plastic or flexible delivery pipe is used, a nylon
safety rope or chain should be utilized for lowering,
securing and raising the pump.
- Attach the power supply cable to the delivery pipe and
to the safety rope with cable clamps at intervals of
about 3 m.
- The power cable should not be taut. It must allow a
certain degree of slackness between the clamps to
avoid the risk of strain caused by expansion of the pipe
during operation.
- Protect the electric power cable from contact with the
well wall to prevent damage.
WARNING: It is advisable to install a gate valve at the
pump output to avoid deposition and a check valve
easily reachable to allow easy pump removal in
cleaning and maintenance operations.
- Single phase pumps are supplied with a float switch
that watches the water level avoiding drops below the
suction strainer.
- For three-phase pumps we recommend the
installation of a control box with a water level protector
and its electrodes.
