6. 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.
