This easy operating guidance provides reference to pump safe application and operating, pump maintenance and installation instructions and pump start-up, operation and stopping procedures. The centrifugal pump needs to be operated only by qualified personnel who have read the whole guide carefully before operating with a centrifugal pump.

Unpacking, moving and lifting instructions

When unpacking the centrifugal pump, you need to stick to some instructions. First of all, you need to check for visible damage on the crate that occurs often during the transportation. Then, carefully remove the packaging material and check the centrifugal pump for some visible markings such as scratches, dents or damages that might occur during the transport. In case of damage, you should report it to the transport company right away.

After the unpacking of the centrifugal pump, you need to know how to move and transport it properly. In fact, it is simple – the pump must always be transported and moved in horizontal position. Just keep in mind the following characteristics: centre of gravity, total weight, lifting points locations and maximum outside dimensions.

For a safe lifting, position ropes or belts on the pump properly and lifting eyebolts with correct movements, to prevent any material damages or personal injuries. Lifting eyebolts fitted on single components of the assembly should not be used to lift the total assembly.

Storage instructions
