CONNECTION OF SUCTION TUBE
IMPORTANT:
Risk of material damage. The suction tube
should be installed so that it does not
transfer mechanical stress to the pump.
Fit a suitable filter if the pumped water is
contaminated or turbid.
NOTE:
• It is recommended to install a non-return
valve to prevent return flow, which can
cause the water in the product and the
suction tube to empty when the product
is not running.
• Use a pre-filter to protect the product
from sand, clay and other particles.
• All the screw unions should be sealed with
jointing tape. Any leakage will allow air to
penetrate the system, which reduces the
pumping capacity.
• Use teflon tape for metal threads and
normal jointing tape for plastic threads.
• All parts of the suction tube should be
installed by qualified personnel.
• The inner diameter of the suction tube
should be at least 25 mm. The suction
tube should be made of material that
does not squeeze at underpressure and
which is resistant to bending.
• The pump’s suction tube should be as
short as possible – long suction tubes
reduce the capacity of the pump.
• The suction tube should run upwards all
the way to the pump, to avoid air
becoming stationary in the tube.
• Make sure that the inlet on the suction
tube is always under the surface of the
water.
