3. Before Starting

Your irrigation pump is self-priming. Before starting for
the first time, the pump has to be filled through the
delivery union with the delivery liquid until it overflows.
Suction Piping
• Fit the water suction pipe so that it points upwards
towards the pump. Absolutely avoid fitting the suction
pipe higher than the pump (formation of air bubbles in
the suction pipe).
• The suction and delivery piping must be fitted so as
not to be able to apply any mechanical pressure on
the pump.
• The suction valve should be situated at least 30 cm.
below the bottom water level.
• Suction pipes that are not airtight suck in air obstructing
suction of the water.
Delivery Piping
During suction, the cut-off parts (sprayers, valves, etc.)
situated in the delivery piping have to be fully open so
that the air in the suction pipe can be freely expelled.

4. Maintenance Instructions

The irrigation pump is entirely maintenance-free.
Should the pump become blocked, first try rinsing. Should
it turn out that the blockage is due to the inefficiency or

time, for instance in the winter period, it is
recommended to rinse out the pump thoroughly with

set it up for use.
CAUTION!
In order to work, the pump must always be filled
with the delivery liquid until it overflows!
Caution: The pump must never run dry. The
manufacturer's warranty is null and void in the
event of damage to the pump caused by its running
dry.
Check that the pump is airtight, in fact not airtight
pipes draw in air preventing the pump from
working properly.
Remedy
• Check voltage.
• Dismantle the hydraulic section and
check whether the impeller rotates

• Put the suction valve into water
(min. 30 cm.)
• Pour water into the suction union.
• Check airtight of the suct. pipe.
• Clean the suction valve.
• Clean the suction rose.
• Check the suction lift.
• Check suction lift.
• Clean the suction rose.
• Set the suct. valve lower down.
• Clean the pump and replace the worn
parts.
