Daily maintenance of the pump
−
Check the oil level in drive unit (1)
Note
If the oil in the pump drive has become whitish in colour, replace the oil. The whitish
colour may indicate the presence of excessive condensation water in the oil.
−
Check the dripping of the gland packing on the piston rod; this should not exceed one drop every five
seconds. It may be necessary to readjust the gland packing at greater lift heights.
−
Check that the dripping water can drain away from the gland packing. The channel must not be plugged
on the outside by dirt and sand that have splashed onto the enclosure.
−
Check whether the machine is still placed properly on the ground on which it stands, in accordance
with the instructions. This is important, because the situation can change as a result of a build-up of
sand/soil around the pump unit.
−
Check the vacuum above the filter in the stone catcher using the vacuum gauge (1) on the stone
catcher. If reading is indicate low vacuum, filter in stone catcher can be blocked. Open stone
catcher covers (2) and (3), clean filter (4).
