For long and trouble-free operation of the pump, following
points should be checked regularly:
- Nominal current (A): Check with amp-meter.
- Pump parts and impeller: Check for possible wear.
Replace defective parts.
- Ball bearings: Check the shaft for noisy or heavy operation
(turn the shaft by hand). Replace defective ball bearings. A
general overhaul of the pump is usally required in case of
defective ball bearings or poor motor function. This work
must be carried out by an authorized
service workshop.
- Cable entry: Make sure that the cable entry is watertight
and that the cables are not bent sharply and/or pinched.
Additionally at pump types with oil chamber:
- Oil level and oil condition in oil chamber:
Put the pump in horizontal position, so that the screw of the
oil chamber is above (at larger pumps: one of both screws).
Remove the screw and infer a small quantity of oil. The oil
becomes greyish white like milk if it contains water. This may
be the result of defective shaft seal. In this case leave the
condition of the shaft seals by a HOMA Service to examine.
The oil should be replaced after 3000 operating hours.
Oil type: Shell Tellus C22, degradable HOMA-Atox (available
on request). Used oil is to be disposed accordingly.

We grant for the described product in the warranty receipt a war-
ranty of declared duration in the warranty receipt. The warranty
starts with the first start up, latest with the day of sale. A warranty
claim can be raised only by presentation of the fill in warranty receipt
together with the purchase receipt.
Our warranty extends only the removal of material defects or produc-
tion defects. Costs for removal and installation of the complained
product at the installation place, costs for the ride of the mechani-
cians to the location and from the installation place as well as costs
for transport are not components of our warranty. Complains caused
by installation faults or operating faults, unsuitable operation condi-
tions, deficient care or improper efforts of repair are out of the ques-
tion of warranty as well as normal wear. Hereby arised costs, espe-
cially costs for checking and transport are bearing by the sender or
operator of the pump. This is also valid for an asserted warranty
claim if a check results that the unit works faultless and is free of
defects. All products have a high quality standard. Each product is
defeated by a streng technical end control before delivery. If the unit
still gives an occasion for a legitimated complain, you have the claim
of an appropriated correction free of charge. Warranty repairs only
must lead from the manufacturer or an authorized agency. Trials of
repair by the customer or non-authorized persons during the war-
ranty, causes an extinguishing of the warranty. A warranty repair
achieved by us does not extend the warranty period. Replaced spare
parts give no reasons for a new warranty period. Extensive claims
are excluderd, especially such as diminution, change or compensa-
tion also for any kind of follow up damages.
To guarantee a quick transaction of a warranty claim, please return
the product together with the warranty receipt, purchase receipt and
declaration of defect carriage paid to the manufacturer (for the
adress see warranty receipt).
Claims caused by damages of transport could be only accepted, if
the damage is established or confirmed by delivery in the presence
of the forwarder, parcel service, train or post.
