- Ball bearings: Check the shaft for noisy or heavy opera-
tion (turn the shaft by hand). Replace defective ball bear-
ings. 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 (avail-
able on request). Used oil is to be disposed accordingly.

We grant for the described product in the warranty receipt a
warranty of declared duration in the warranty receipt. The war-
ranty 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
production defects. Costs for removal and installation of the
complained product at the installation place, costs for the ride of
the mechanicians to the location and from the installation place
as well as costs for transport are not components of our war-
ranty. Complains caused by installation faults or operating faults,
unsuitable operation conditions, deficient care or improper efforts
of repair are out of the question of warranty as well as normal
wear. Hereby arised costs, especially 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
warranty, causes an extinguishing of the warranty. A warranty
repair achieved by us does not extend the warranty period. Re-
placed spare parts give no reasons for a new warranty period.
Extensive claims are excluderd, especially such as diminution,
change or compensation 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 manufac-
turer (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.
