9. Warranty
The present device was manufactured and inspected according to the latest methods. The
seller warrants for faultless material and workmanship in accordance with the legal
regulations of the country in which the device was purchased. The warranty period begins
with the day of the purchase and is subject to the provisions below:
Within the period of warranty, all defects which are to be attributable to defective materials or
manufacturing will be eliminated free of charge. Any complaints are to be reported
immediately upon their detection.
The warranty claim becomes void in the case of interventions undertaken by the purchaser
or by third parties. Damage resulting from improper handling or operation, incorrect setting-
up or storage, inappropriate connection or installation or Acts of God or other external
influences are excluded from warranty.
Parts being subject to wear and tear, such as the pump wheel (impeller) and mechanical
shaft seals are excluded from warranty.
All parts were manufactured using maximum care and high-quality materials and are
designed for a long lifecycle. It should be understood, however, that the wear and tear
depends on the kind of use, the intensity of use and the internals of maintenance. Complying
with the installation and maintenance information contained in the present operating
instructions will therefore considerably contribute to a long lifecycle of these wearing parts.
In case of complaints, we reserve the option of repairing or replacing the defective parts or
replace the entire device. Replaced parts will pass into our property.
Claims for liquidated damages are excluded unless they are caused by wilful acts or
negligence on the side of the manufacturer.
The warranty does not provide for any claims beyond those referred to above. The warranty
claim has to be evidenced by the purchaser in the form of the submission of the sales
receipt. The present warranty commitment is valid in the country in which the device was
purchased.
