Servicing; Guarantee Regulations; Recognising And Repairing Of Mistakes - Profi-pumpe BRUNNEN-STAR 370-5 Operating Instructions Manual

THE MANUFACTURER EXPLAINS:
l To take over no responsibility in the case of accidents or damages on the basis of careless-
ness or disregard to the instructions in this book.
l To reject every responsibility for the damages which originate from the improper use of the pump.

8. SERVICING

Under normal pumping conditions the pump requires no servicing. From an operating
period (with clear water) of approx. 2000 hours the mechanical components should be
checked: impeller wheels, chambers, sealing rings etc. on wear and if necessary be
changed. After 3000 pumping hours the oil in the chamber should also be changed, if
necessary (only with oil-dipped engine types!). Please, only fill it up to 80% and check
the sealing rings always for density.
With abrasive materials like sand the servicing duration can become shorter.
The following controls should be carried out regularly:
l Intactness of the electric cable
l That the connection hoses are not bent or broken
l Cleanness of the pump medium
Moreover, the pump should be emptied with risk of frost, be washed out with clear water
and stored dry.
